Heat Mitigation in Composite Decking: What Is It, and Will It Make My Deck Less Hot?

Highlights from this Article:

• All composite decking gets hot in direct sun. Heat mitigation technology reduces how hot, but does not eliminate the issue.
• Color is the single biggest factor in how hot a deck board gets. Lighter colors stay significantly cooler than darker ones, regardless of the product line.
• Heat mitigation matters most when you want a darker color and your deck sits in full or near-full sun.
• Trex’s SunComfortable technology is now available across the Transcend Lineage, Select, and Enhance lines. TimberTech’s Advanced PVC offers comparable performance across its Vintage, Landmark, and Harvest collections.
• Shade structures are a complementary strategy worth considering alongside material and color selection.

Worried about your toddler’s toes, or your pet’s paws? Wondering whether heat mitigation in composite decking will eliminate the problem of a hot deck entirely? We want to clear this up, because it’s a feature that’s genuinely useful in the right circumstances and genuinely oversold in others.

Ann Arbor Decks is a certified TrexPro Platinum contractor, and our team has gone through Trex University, the company’s training program for professional installers. Heat mitigation came up as a significant topic, and what we took away from that training lines up with what we see in the field: the technology is real and it works, but color is still the dominant variable in how hot your deck gets.

The Basic Physics

Dark surfaces absorb more solar energy than light ones. This applies to everything from car roofs to T-shirts to deck boards. A dark composite board sitting in full afternoon sun is going to get hotter than a light one from the same product line, regardless of what heat mitigation technology is built into the shell. That’s not a flaw in the technology; it’s physics, and no composite manufacturer has figured out how to fully engineer around it.

What heat mitigation technology does is reduce heat absorption within a given color range by engineering the board’s shell to reflect more solar energy rather than absorbing it. Trex calls their version SunComfortable technology. TimberTech Advanced PVC boards achieve a similar result through their capped polymer construction. Both approaches make a meaningful difference when comparing boards of similar colors, but they don’t close the gap between a light board and a dark board of the same product.

The practical upshot, which Trex’s own training materials make clear: if you want a cooler deck, choose a lighter color first. Heat mitigation technology is an additional benefit on top of that choice, not a substitute for it.

When Heat Mitigation Actually Matters

For a lot of Michigan decks, heat mitigation is less critical than the manufacturers’ marketing might suggest. A deck that faces north, gets significant tree shade, or is only in direct sun for a few hours a day is unlikely to reach the temperatures that make barefoot comfort a real concern, regardless of color.

Where heat mitigation becomes genuinely important is the combination of two factors: a deck in full or near-full sun, and a desire for a darker color. If your deck faces south or west and gets unobstructed afternoon sun, and you’re drawn to the richer, darker board colors that are currently popular, heat mitigation technology is a real consideration worth paying for. In that scenario, choosing a product line with SunComfortable or Advanced PVC technology in a medium-to-dark color will perform meaningfully better underfoot than a standard composite board of the same color.

If you’re choosing a lighter color regardless, the benefit of heat mitigation narrows considerably. You’ll still get a cooler board than a darker color from a premium line, but the color choice itself is doing most of the work.

Trex: SunComfortable Technology Across Three Lines

Trex introduced their SunComfortable heat-mitigating technology in the Transcend Lineage collection in 2022, their premium offering with on-trend, understated colors and a 50-year warranty. Since then, they’ve expanded it. As of 2025, SunComfortable technology is available in select colors across Trex Select and Trex Enhance as well, making it accessible at lower price points than when it launched.

A few things worth knowing about the Trex lines:

• Trex Transcend Lineage: The line where SunComfortable technology is most fully implemented. Designed specifically with heat it mind, it’s a great choice for homeowners with small children or pets. Backed by a 50-year warranty. This is the line to specify when heat mitigation is a primary concern.
• Trex Transcend: Trex’s best-selling line with a wide range of colors and a 50-year warranty. Does not carry the same heat-mitigating technology as Lineage, but remains a strong performer. Color choice matters here more than in the Lineage line.
• Trex Select: Mid-tier option with a 35-year warranty. Select now includes SunComfortable technology in several of its color offerings as of 2026.
• Trex Enhance: Trex’s entry-level composite line with a 25-year warranty. Two heat-mitigating colors (Honey Grove and Tide Pool) were added to the Enhance line in 2024, making this the first time heat mitigation technology has been available at Enhance’s price point.

Trex is clear in their materials that even Transcend Lineage boards will get hot on a hot day. Trex cites reductions of up to 35 degrees Fahrenheit in their laboratory testing, though it’s worth knowing what that comparison actually involves: their test compares Lava Rock (a dark color, without SunComfortable) to Salt Flat (a light color, with SunComfortable). That means the 35-degree figure reflects both the technology and a significant color difference working together, not the technology alone. Barefoot caution on a hot summer afternoon is still warranted, particularly for young children.

TimberTech: Advanced PVC

TimberTech takes a different material approach. Their heat-performing products are Advanced PVC boards rather than wood-composite, which gives them a different set of performance characteristics. TimberTech’s Advanced PVC collections report surface temperatures up to 30 degrees cooler than many competitive composite products, and that performance extends across their Vintage, Landmark, and Harvest collections.

TimberTech’s own guidance echoes what Trex University teaches: even within the Advanced PVC line, lighter colors will outperform darker ones on heat. The material science helps, but color still drives most of the outcome. TimberTech Advanced PVC also comes with a 50-year fade and stain warranty and a lifetime limited product warranty, making it a great long-term investment.

One practical note on PVC vs. composite: PVC boards can heat up faster than composite in the first few minutes of sun exposure. Given time, though, standard composite boards typically get hotter overall. If you’re evaluating samples, TimberTech recommends letting the samples sit in full sun for at least two hours before comparing temperatures for an accurate read.

Don’t Overlook Shade

Whatever material and color you choose, shade structures are an effective and often underutilized tool for heat management. A pergola with a retractable canopy, a sail shade, or even a well-positioned umbrella can dramatically reduce the surface temperature of any deck board in direct sun. We install Trex Pergola systems, which include motorized and manual retractable canopy options, and they’re a popular addition for homeowners who want the flexibility to open up the deck on mild days and block the sun when it’s intense.

If heat is a significant concern for your project, the conversation about shade is worth having alongside the conversation about materials and color. In many cases, a combination of a mid-range board in a lighter color, strategic use of outdoor carpet, plus a shade structure gets you further than an expensive heat-mitigating product line alone.

Frequently Asked Questions

Does heat mitigation technology mean my deck won’t get hot? No, and any manufacturer that implies otherwise is overselling it. All deck surfaces get hot in direct sun. Heat mitigation technology reduces how hot compared to standard composite boards of a similar color, and it does so meaningfully. But on a hot July afternoon with the sun bearing down, you’ll still want footwear, especially for young children.

Is color really more important than the product line when it comes to heat? Yes, according to both the manufacturers and what we’ve learned through Trex University. A lighter color from a standard line will typically outperform a darker color from a premium heat-mitigating line. The ideal combination is a lighter color and a product with heat mitigation technology built in.

My deck is mostly shaded. Do I need to worry about heat mitigation? Probably not as a primary concern. If your deck is under a tree canopy or on a north-facing exposure that doesn’t get significant direct sun, heat is unlikely to be a limiting factor in your material or color selection. Focus on the colors and materials you prefer.

Does my deck’s orientation affect how hot it gets? Significantly. South- and west-facing decks get the most direct sun, particularly in the afternoon when temperatures are highest. If your deck faces south or west and is unobstructed, heat mitigation is worth paying attention to. North- and east-facing decks get considerably less intense sun exposure.

Can you help me figure out whether heat mitigation matters for my specific deck? Yes. During our free on-site consultations, we look at your deck’s orientation, sun exposure, and the color palette you’re drawn to, and we give you an honest read on whether a heat-mitigating product line is worth the investment for your situation. Sometimes it is. Sometimes color selection alone gets you where you need to be.

Cable Railing for Michigan Decks: Here’s What to Think About

Highlights from this Article:

• Cable railing preserves views and gives a deck a clean, modern look at a lower cost than glass.
• Horizontal cable runs are the most common, but vertical cable is worth considering for households with young children.
• Stainless steel cable is durable and low-maintenance, but cables can loosen over time and may need periodic retensioning.
• Post spacing can be closer with cable railing than with standard balusters, and some designs require small ‘intermediate pickets’ to lend extra support the cables.
• Ann Arbor Decks installs various aluminum and composite brands, including Key-Link Cable Rail, Westbury VertiCable, Trex Cable Railing, and DecKorators cable systems.
• Ann Arbor Decks also installs custom wood-and-cable railing, like pine, cedar or Ipe railings with horizontal cables.

Skip down to the quick comparison table or the FAQs.

Cable railing has become one of the most popular railing upgrades we install — and it’s easy to see why. The thin horizontal (or vertical) stainless steel runs largely disappear from view, keeping your sightlines open without the cost and maintenance demands of a full glass panel system. For decks that face a wooded backyard, a garden, or any view worth preserving, cable railing is often the most practical choice. Plus, it gives a modern and very attractive look.

Horizontal cables work well as infills for natural cedar railings and rail posts. This is a great choice for homeowners looking for the upscale cabin, outdoorsy look. To achieve a modern and sleek style, homeowners choose

Horizontal vs. Vertical Cable

Most cables run horizontally. This is the look most people picture when they think of cable railing, and it works really well in the majority of situations.

Vertical cable runs the cables up and down between a bottom and top rail, similar in concept to traditional balusters but using cable instead. The visual effect is subtly different (slightly more structured than horizontal) and it addresses one concern that comes up with horizontal systems: climbability. Horizontal cables can act as a ladder for determined young children. If that’s a consideration in your household, vertical cable is worth discussing.

Ann Arbor Decks installs both orientations. The right choice depends on your household, your aesthetic preference, and sometimes the specific configuration of your deck.

Code Requirements

Cable railing must meet Michigan Residential Code requirements for railing systems. The key spacing requirement is that openings between cables cannot allow a 4-inch sphere to pass through, the same standard that applies to baluster spacing. This determines both the number of cable runs required and, for horizontal systems, the spacing between them. Your installer’s drawings need to reflect code-compliant spacing, which is something we verify on every project before the permit application goes in.

Post Spacing

This is the detail that most often surprises homeowners. Cable railing exerts significant lateral tension on the posts that anchor it, particularly the corner and end posts, which bear the full load of the cable runs. To handle that tension properly, posts in a cable railing system are typically spaced more closely together than in a standard baluster system. Aluminum corner and terminal posts are also often larger and more heavily anchored than intermediate posts.

What this means practically: a cable railing system requires more posts than you might expect, which affects the visual rhythm of the railing and adds some cost relative to a standard baluster system. It’s not a drawback so much as a design reality that we plan for.

Maintenance: Lower Than You’d Think, But Not Zero

Stainless steel cable is genuinely low-maintenance. It doesn’t rust, rot, or require painting, and it holds up well through Michigan’s freeze-thaw cycles. Occasional cleaning with mild soap and water is typically all it needs to stay looking sharp.

The one maintenance item to be aware of: cables can loosen over time, particularly in the first year or two after installation as the system settles. Periodic re-tensioning (tightening the cable at the tensioner fittings, which keeps the system looking taut and performing correctly). This is a straightforward task that most homeowners can handle themselves once shown how.

Brands We Install

We’re selective about the cable railing systems we install because the quality of the hardware (particularly the tensioners, fittings, and post systems) matters significantly for long-term performance. The brands we work with regularly:

• Westbury VertiCable: Westbury makes a particularly clean vertical cable system, and their horizontal offerings are equally solid. Good choice for homeowners who want a refined, architectural look.
• Trex Signature X Series Cable Railing: Integrates well with Trex composite decking for a cohesive material story from deck surface to railing. A natural fit if you’re already building with Trex.
• Key-Link Cable Rail: A well-regarded system with a strong reputation for hardware quality and a wide range of post finish options. Key-Link offers both vertical and horizontal cable options.
• ViewRail Cable Railing: A sleek, modern-looking system with a variety of configurations, including over-the-post cocktail rails, LED rail lighting, and very fine thin rod rail systems that look like cables, without the need to re-tension.
• DecKorators Cable Railing: A reliable, traditional system with good design flexibility. Worth considering depending on the specific configuration of your project.

Each of these systems has its own post profiles, finish options, and hardware details. During the design phase, we’ll recommend the system that best fits your deck’s configuration, aesthetic, and budget.

Custom Wood Posts and Top Rails: Cedar and Ipe

One option worth knowing about: we also build custom cable railing systems with cedar or Ipe posts and top rails. If you’re building a cedar or Ipe deck surface and want the railing to match, or if you simply want the warmth and character of natural wood framing your cable runs, this is something we do and do well. Ipe in particular pairs beautifully with stainless steel cable — the rich, dark hardwood and the clean metal lines complement each other in a way that aluminum post systems simply can’t replicate. Cedar offers a similar warmth at a more accessible price point.

Cable vs. Other Railing Options at a Glance

	Cable Railing	Glass Railing	Standard Balusters
Sightlines	Very open	Most open	Partially obstructed
Cost	Mid-to-upper range	Upper range	Most accessible
Maintenance	Low (occasional retensioning)	Low (regular cleaning)	Low to moderate
Airflow	Excellent	Blocked	Good
Child safety	Consider vertical orientation	Not climbable	Not climbable
Post spacing	Closer than standard	Varies by system	Standard

Frequently Asked Questions

Is cable railing safe? Yes, when properly installed to code. The 4-inch maximum opening requirement is the same standard applied to all railing systems and is designed to prevent children from getting through or stuck. The posts and hardware must be correctly specified and anchored for the cable tension loads involved. Professional installation matters here. Improperly anchored terminal posts are a safety issue.

How does cable railing compare in cost to glass? Cable railing is generally less expensive than glass railing, particularly frameless glass systems. It’s more expensive than standard aluminum or composite balusters. As we noted in our glass railing post, the cost varies by system and configuration. The best way to compare is to request quotes for both and see what the difference looks like for your specific deck.

Will the cables block my view? Much less than you might expect. Horizontal stainless steel cables are thin and largely recede from view, especially when you’re seated. The effect is noticeably more open than traditional balusters. That said, the top rail and posts are still visible. Cable railing isn’t as visually unobstructed as a frameless glass system, but it comes close at a lower price point.

Can cable railing be added to an existing deck? Often yes, provided the deck’s existing framing is sound and the posts can be properly anchored for cable tension loads. We assess this during our on-site consultation. In some cases, the existing post anchoring needs to be upgraded before a cable system can be installed correctly.

Does cable railing require a permit? Railing replacement or installation on an elevated deck sometimes requires a building permit in Washtenaw County townships and municipalities. Ann Arbor Decks handles the permitting process for every railing project we install.

Glass Railing for Michigan Decks: Here’s What to Think About

Highlights from this Article:

• Glass railing offers unobstructed views and a clean, modern aesthetic, but it comes with real maintenance, airflow, and hardware considerations that matter in Michigan’s climate.
• Tempered glass is the standard safety choice for outdoor deck railings, but laminated glass (a much more expensive option), is sometimes recommended.
• Glass panels block airflow, which can make a deck feel warmer in summer. Mixing glass panels with other railing infill types (like balusters or cables) is a popular solution.
• Hardware, not glass, is typically the first thing to show wear in Michigan’s freeze-thaw climate. Quality matters here.
• Cost varies significantly depending on the system you choose. Fully frameless installations are the most expensive; aluminum-framed systems are more accessible.

Skip down to the cost overview or the FAQs.

There’s a reason glass railing has become one of the most requested upgrades in deck design. When it’s done well, it makes a deck feel larger, lighter, and more connected to the yard beyond it. If you have a view worth preserving (a wooded backyard, a garden, a waterfront), glass railing lets you keep it front and center.

Before you commit, there are practical questions worth thinking through, especially here in Michigan, where the climate puts outdoor materials through their paces year-round. This post walks through the most important ones.

Safety: What Makes Glass Railing Structurally Sound

The first question many homeowners ask is simply: is glass railing safe? The answer is yes, when it’s properly specified and installed. Here’s what that means in practice.

Tempered Glass

Tempered glass is the standard safety specification for deck railing. It’s been heat-treated to be significantly stronger than ordinary glass, and crucially, when it does break from a severe impact, it shatters into small, relatively harmless fragments rather than large dangerous shards. Building codes in Michigan, as in most states, require tempered glass for railing applications.

Laminated Glass

Laminated glass takes safety a step further. It consists of two glass layers bonded together with an interlayer (typically a plastic film) that holds the glass together if it breaks. Rather than shattering, a broken laminated panel tends to crack and hold its shape, which is particularly relevant for elevated decks, where a failed panel could be a falling hazard. Some installations use a tempered-laminated combination that delivers the strength benefits of both.

The Three Main Glass Railing Systems

At Ann Arbor Decks, we install three primary types of glass railing systems, each with a different aesthetic and price point.

Aluminum-Framed Glass Panels

Aluminum-framed systems enclose each glass panel in an aluminum frame which is hung between a top and bottom rail. They’re the most economical glass railing option and are very durable. Aluminum handles Michigan’s freeze-thaw cycles well and requires minimal maintenance. Framed glass is a great way to enjoy the view while still keeping that aluminum top rail to hold or lean on. The traditional posts also allow you to install lighted rail post caps. In our experience, this is the most popular choice for Ann Arbor area homeowners with elevated decks.

Trex Signature Glass — a framed glass rail system.

Semi-Frameless (Post-Mounted) Glass Panels

Semi-frameless systems use posts (typically aluminum or stainless steel) spaced at intervals, with glass panels fitted between them. You get most of the visual openness of a frameless system at a more accessible price point. The posts provide additional structural support and give the installation some flexibility in terms of panel sizing.

Fully Frameless Glass Panels

Frameless systems use thick glass panels (typically 1/2 inch or more) anchored at the base with a metal shoe and on the sides with small clips. The result is the cleanest, most unobstructed look available, almost invisible from certain angles. Frameless systems are also the most expensive option and require precise installation to perform correctly. They work beautifully on elevated decks with views worth showcasing.

Michigan Climate Considerations

Michigan’s climate and glass railing: what to consider.

Airflow and Heat Retention in Summer

This is one of the most practical considerations that often surprises homeowners. Glass panels are solid barriers that block wind almost as effectively as a solid wall. On a warm Michigan summer afternoon, a deck fully enclosed with glass railing can feel noticeably hotter than one with open balusters or cable railing, because there’s no airflow coming through at railing height.

One approach we frequently discuss with customers: mixing glass panels with other railing types. For example, using glass on the sides of a deck where you want to block a neighbor’s sightline or a prevailing wind, while using cable or aluminum balusters on the sections that face your yard and view. This gives you the visual openness of glass where it matters most, without sacrificing cross-ventilation across the whole deck.

Pollen and Hard Water Buildup

Michigan springs are generous with pollen, and if your area has hard water (common throughout Washtenaw County), sprinkler overspray or rain splash can leave mineral deposits on glass panels. Plan for regular cleaning as part of your deck maintenance routine. Most glass panels can be cleaned with a standard glass cleaner and a soft cloth; avoid abrasive pads that can scratch the surface. Anti-spotting treatments and hydrophobic coatings (like Rain-X) are available for glass panels and are worth considering if low-maintenance is a priority for you.

Cost: What to Expect

Glass railing costs vary significantly depending on which system you choose. As a general orientation:

• Aluminum-framed glass is the most budget-friendly glass option and is competitive with mid-range traditional railing systems.
• Semi-frameless post-mounted glass sits in the mid-to-upper range, noticeably more than standard aluminum balusters, but delivering a premium aesthetic in return.
• Fully frameless glass is the most expensive option, reflecting both the thicker glass specification and the precision installation it requires.

The best way to understand what glass railing will cost for your specific deck is an on-site consultation. We’ll walk through the options with you and provide a clear, itemized quote so you can compare systems side by side.

Is Glass Railing Right for Your Deck?

At Ann Arbor Decks, we don’t steer customers away from glass railing. It’s a genuinely excellent product when it fits the situation. What we do is make sure you’re going in with a clear picture of what it involves, so the choice you make is one you’ll be happy with for years.

Glass railing tends to shine brightest when the deck has a view worth framing, when the homeowner is committed to occasional cleaning and maintenance, and when the system is specified with quality hardware suited to Michigan’s climate. When airflow is a concern, a mixed railing approach often delivers the best of both worlds.

Frequently Asked Questions

Is glass railing safe for homes with children or pets? Yes, when properly installed. Tempered glass is engineered to withstand significant impact, and the panels are anchored to meet building code load requirements. As with any railing system, installation quality matters. Panels need to be correctly secured and the system needs to meet local code for height and structural performance.

How do I clean glass railing panels? Standard glass cleaner and a soft microfiber cloth handle most cleaning needs. For hard water deposits or pollen buildup, a diluted white vinegar solution works well. Avoid abrasive scrubbers or steel wool, which can scratch the glass surface. Hydrophobic coatings (Think Rain-X) applied at installation can significantly reduce how often cleaning is needed.

Will glass railing make my deck feel hotter in summer? It can, particularly on decks that are fully enclosed with glass on all sides. Glass panels block airflow at railing height, which can make the deck feel much warmer on still summer days. Mixing glass panels with open railing sections on some sides of the deck is a practical way to preserve views while maintaining cross-ventilation.

How does glass railing hold up to Michigan winters? The glass itself is very durable in cold weather. Both tempered and laminated glass handle freeze-thaw cycles without issues. The hardware deserves more attention. Stainless steel and marine-grade aluminum components hold up significantly better than lower-grade hardware over years of Michigan winters. Ask about hardware specification when comparing systems.

Does glass railing require a building permit? Possibly. Railing replacement or installation sometimes requires a permit in local townships and municipalities. If a permit is required, Ann Arbor Decks will handle the permitting process for our installations, so you don’t need to navigate that yourself.

Can glass railing be added to an existing deck? Often yes, provided the deck’s existing framing and rim joists are in sound condition and can support the anchoring requirements of the glass system. We assess this during our on-site consultation. In some cases, minor framing reinforcement and some deck board replacement are needed before glass railing can be installed.

While most deck builds are not too complicated, the process isn’t just about framing and decking. There’s design work, HOA approval, zoning and permitting, material lead times, inspections, and sequencing to coordinate. Done well, most of that happens in the background and you experience it as a smooth, well-managed project.

This post walks through the process we follow at Ann Arbor Decks for every new build, so you know what to expect before you pick up the phone.

Step 1: Initial Consultation

Every project starts with a free on-site consultation, typically 45 minutes. We come to your home, walk the space with you, and talk through what you’re envisioning (size, materials, railing style, any special features like built-in lighting, a pergola, or an outdoor kitchen area).

We’re also looking at the site itself during this visit: grade, existing landscaping, how the deck will attach to the house, access for equipment and materials, and anything else that affects how the project gets designed and built. A deck that looks simple on paper sometimes has site conditions that require additional planning. We’d rather find those things at the consultation than mid-build.

After the consultation, we put together a written quote with clear, itemized pricing. No vague estimates. You’ll see what you’re paying for.

Step 2: Design and Drawings

Once you decide to move forward, we produce design drawings for your deck in-house. These aren’t rough sketches: they’re the detailed drawings that go to the municipality with your permit application, showing dimensions, framing layout, footing locations and sizes, ledger attachment detail, and railing specifications.

We’ll review your deck design with you first, so you have the opportunity to make adjustments while changes are still easy. This is also when we finalize material selections if you haven’t already.

Step 3: Material Selection

If you haven’t settled on materials by the end of the consultation, the design phase is when we nail that down. The main decisions are decking surface (composite or wood, and which product line), railing system, and any special features. We can walk you through samples and help you think through what suits your home, your yard, and your maintenance preferences.

Material lead times vary. Most standard composite products are readily available, but custom colors, specialty railing systems, or pergola kits may have longer lead times that affect the project schedule. We factor this in when we give you your build timeline.

Step 4: HOA Approval (If Applicable)

If your neighborhood has a homeowners association, their approval typically needs to come before you can apply for a municipal building permit. HOA review processes vary considerably. Some associations turn around approvals in a week or two; others meet only quarterly and require submissions well in advance of their meeting dates.

If you have an HOA, let us know at the consultation. We can provide the drawings and documentation their review board typically requires, but the submission and approval process runs through you as the homeowner. We’ve found it’s worth understanding your HOA’s timeline early, as it can be the longest single variable in the pre-construction phase.

Step 5: Permit Application

Ann Arbor Decks handles the building permit application for every project. You don’t need to visit municipal offices or navigate the application yourself. We take care of it.

If you need Ann Arbor historical permissions, that is something you would need to obtain first. We can assist you in any way possible.

Washtenaw County encompasses many Townships and municipalities, and permitting timelines vary more than most homeowners expect. The City of Ann Arbor, Saline, Dexter, Chelsea, Pittsfield Township, Ypsilanti, and the surrounding townships each have their own building departments with their own review processes and workloads. Some turn permits around in a week or two; others can take considerably longer, particularly during the busy spring and summer building season.

A few things that affect permitting in this area:

• Zoning setbacks vary by municipality. How close your deck can be to a property line, easement, or structure depends on local zoning rules. Where possible, we obtain zoning approval before submitting your permit, so there are no setback surprises after the permit is filed.
• Deck drawings must meet Michigan Residential Code requirements. Our in-house drawings are prepared with code compliance in mind, which helps avoid revision requests that delay permit issuance.
• Permit fees vary by municipality and project scope. These are passed through to you at cost, plus our administrative fees. The permit costs will be clearly broken out for you on your contract.

Step 6: Site Preparation

Once the permit is in hand, we can more exactly schedule your project start date. If there’s an existing deck or structure being removed, demolition and debris hauling happens first. We handle all of that, including proper disposal of any pressure-treated lumber, which Michigan requires be taken to an authorized facility rather than placed in regular trash.

We also arrange to have Miss Dig mark utility lines before any digging begins. In Michigan, this means we call MISS DIG (dial 811) to have underground utilities located and flagged. This is a legal requirement before any excavation and a step we take seriously. Hitting an unmarked utility line is dangerous and costly. When flags show up in your lawn, you’ll need to leave them be until we remove them for you.

Step 7: Footings and Framing

This is the structural core of your deck, and it’s where the quality of a build is really established, even though most of it ends up hidden once the decking goes down.

In Michigan, deck footings must extend below the frost line, which is 42 inches. This prevents the freeze-thaw cycle from heaving posts out of the ground over time (a common cause of deck instability on improperly built structures). We pour concrete footings to the required depth and allow appropriate cure time before framing begins. The inspector will come out to approve the size, position and depth of the holes (the ‘footings inspection’).

Framing involves setting posts, installing beams and joists, and attaching the ledger board to the house. If your deck is ledgered (not all decks are attached), this ledger connection is one of the most structurally critical details in any attached deck, and we take care with both the attachment method and the flashing that protects your home’s rim joist from water intrusion. A ledger that allows water behind it is a slow-motion problem that doesn’t show up until significant damage has already occurred.

Depending on your municipality, a framing inspection may be required before decking can be installed. Where required, we schedule and coordinate this inspection.

Step 8: Decking and Railing Installation

With framing complete and inspection passed, decking boards go down. Hidden fastener systems (which leave a clean surface with no visible screw heads) are standard on most of our composite installations. Stair construction, if your deck includes stairs, happens during this phase as well.

Railing installation follows. Whether you’ve chosen cable, glass, aluminum balusters, or a composite system, this is when the deck starts to look finished. We pay attention to detail at this stage (consistent spacing, plumb posts, secure connections) because the railing is both a safety system and one of the most visible design elements of the finished deck.

Step 9: Final Inspection

A final building inspection takes place before the permit is closed out. An inspector from the local building department visits the site and reviews the completed deck against the approved permit drawings and applicable code requirements, like stair riser heights, stair widths, and stair handrail requirements. We schedule and coordinate this inspection for you.

Once final inspection is passed, the permit is closed and the deck is officially yours to enjoy.

Frequently Asked Questions

Do I need a permit to build a deck in Washtenaw County? In virtually all cases, yes. Any attached deck (and most freestanding decks above a certain size) requires a building permit in Washtenaw County municipalities. Building without a permit creates problems when you sell your home and can result in costly remediation if the unpermitted structure is discovered. Ann Arbor Decks handles the permit application for every project we build.

How long does the whole process take from first call to finished deck? It varies by project, but the permitting phase is usually the longest variable. Once a permit is in hand, the active build time for your specific deck is something we are happy to provide. We also coordinate with you on your expected project start date, staying in good communication as the project approaches.

What if my HOA rejects the design? We work with you to adjust the design to meet HOA requirements and resubmit. Most HOA rejections involve aesthetic concerns (materials, colors, or height) that can be addressed without fundamentally changing the project. The important thing is to start the HOA process early so a revision doesn’t significantly delay the overall timeline.

What is MISS DIG and why does it matter? MISS DIG is Michigan’s underground utility notification service. Before any digging begins, Michigan law requires contractors to contact MISS DIG (by dialing 811) so that underground utilities (gas, electric, water, communications lines) can be located and marked. We handle this as a standard part of every project requiring digging, before excavation starts. MISS DIG won’t cover sprinkler lines, so we do ask that you have your landscaper move those before we start work, if possible.

Why do footings need to go 42 inches deep? Michigan’s frost line (the depth at which the ground freezes in winter) is 42 inches. Footings that don’t extend below the frost line are subject to frost heave, where freezing and thawing soil pushes the footing (and the post above it) up and out of position over time. This leads to decks that become unlevel, unstable, or structurally compromised. Frost-depth footings are required by code and are simply the right way to build in Michigan.

Can I start using my deck before the final inspection? Technically the deck isn’t permitted for occupancy until the final inspection is passed and the permit is closed. We schedule final inspections promptly at project completion. There’s no reason for this step to take long once the work is done.
