Building an outdoor deck in Southeast Michigan is a rewarding way to expand your living space, but it comes with a range of costs that homeowners should understand upfront. This comprehensive guide breaks down the full cost of building a new deck – from materials and sizes to labor, permits, and add-ons – all with a focus on Southeast Michigan’s regional considerations. We’ll also provide budgeting tips, return on investment (ROI) insights, and a comparison of DIY vs. professional installation. With advice informed by local expertise (including Mitten Made Basements’ experience building decks in Michigan), you’ll be well-equipped to plan a beautiful deck that fits your budget and needs.
Deck Material Options and Cost Breakdown
One of the biggest cost factors is your decking material. Different materials have varying price points and maintenance requirements, which in turn affect long-term value. Below is a breakdown of common deck materials – pressure-treated wood, cedar, composite (e.g. Trex), and PVC – with typical installed cost ranges in Southeast Michigan:
| Decking Material | Cost per Sq. Ft. Installed | Maintenance | Lifespan |
| Pressure-Treated Lumber | $25 – $50 per sq ft | High (annual sealing/staining) ~$500/yr | ~10–20 years |
| Cedar (Natural Wood) | $30 – $47 per sq ft | High (annual sealing, upkeep) similar to PT | ~15–20 years (with maintenance) |
| Composite (Trex, etc.) | $40 – $80 per sq ft | Low (wash occasionally, ~$5–$15/yr) | ~25–50 years |
| PVC (Vinyl) | ~$45 – $90 per sq ft (about 10–20% higher than composite) | Low (very minimal upkeep) | ~25–50 years (very durable) |
Pressure-Treated Wood: Pressure-treated pine is the most budget-friendly option. In Southeast Michigan, an installed pressure-treated deck costs roughly $25–$50 per square foot. That means a basic 200 sq. ft. deck might be $5,000–$10,000. Pressure-treated lumber is chemically treated to resist rot and insects, but it requires annual maintenance (sealing, staining) to maximize its ~15-year lifespan. Maintenance can run about $450–$850 per year on average if you hire it out, or many hours of DIY work. This upkeep is important in Michigan’s climate to prevent warping or decay from our freeze-thaw cycles and humid summers.
Cedar Wood: Cedar is a popular natural wood upgrade known for its beauty and natural rot resistance. Cedar decks in our region typically cost around $30–$47 per square foot installed, so a 300 sq. ft. cedar deck might range $9,000–$14,000. Cedar doesn’t require chemical treatment and has oils that resist pests, but it still needs regular sealing or staining (at least every couple of years) to prevent weathering. Maintenance effort and costs are similar to other wood – plan on annual cleaning and periodic refinishing to keep that rich cedar look. With good care, a cedar deck can last 15–20 years in Michigan’s environment.
Composite Decking (e.g. Trex): Composite decking is a low-maintenance alternative made from wood fibers and plastic. It comes with a higher upfront cost – about $40–$80 per square foot installed on average (Trex-brand composites often around $45–$70 per sq. ft.). For example, a 300 sq. ft. composite deck might cost roughly $12,000–$24,000 installed. The payoff is in durability and ease: composites don’t need sanding, staining, or sealing, and simply require occasional washing (perhaps $5–$15 in cleaning supplies per year). They resist rot, insects, and warping in Michigan’s weather. A quality composite deck can last 25+ years, far longer than wood, which adds to its long-term value. Tip: Composite brands like Trex often carry 25-year warranties, and their color is built-in, so you won’t be repainting the deck every few years.
PVC (Vinyl) Decking: PVC decking (100% synthetic vinyl boards) is another premium option. It’s typically the most expensive upfront, often 10–20% higher cost than composite decking. In practice, that could be about $50–$90 per sq. ft. installed. For instance, a small 12’×12’ PVC deck might cost $14,000–$17,000 vs. $12,000–$15,000 for composite. PVC decks are extremely durable and virtually maintenance-free (just wash them as needed). They won’t absorb moisture or fade like wood, and some “cool touch” PVC products stay cooler underfoot on hot summer days – a consideration if you have kids or pets. PVC can easily last 25–50 years as well. The trade-off is the higher initial price and a slightly more synthetic appearance compared to the natural look of wood composites.
Exotic Hardwoods (Optional): While not as common, some Michigan homeowners consider tropical hardwoods like Ipe or Tigerwood for their deck. These woods are extremely durable and gorgeous, but very expensive – often in the range of $55–$100 per sq. ft. installed. They can last 40+ years, but require special tools and still need periodic oiling. Exotic hardwoods are usually a splurge reserved for high-end projects; most homeowners in Southeast Michigan opt for the more prevalent options above.
Deck Size and Design: How Dimensions Affect Cost
Deck size is a straightforward but major cost driver: larger decks require more materials and labor, increasing the total price. However, there are economies of scale – a bigger deck often costs less per square foot than a small deck because fixed costs (permits, site prep, mobilization) are spread out. Below are example cost ranges for different deck sizes (using pressure-treated wood as the baseline):
| Deck Size | Approx. Square Footage | Pressure-Treated Deck Cost | Composite Deck Cost |
| Small Deck (approx 200 sq ft) | 12’ x 16’ (192 sq ft) | ~$6,000 – $12,000 (basic design) | ~$8,000 – $16,000 (composite) |
| Medium Deck (approx 300 sq ft) | 15’ x 20’ (300 sq ft) | ~$10,000 – $15,000 (pressure-treated) | ~$15,000 – $24,000 (composite) |
| Large Deck (400+ sq ft) | 20’ x 20’ (400 sq ft) | ~$10,000 – $20,000 (pressure-treated) | ~$29,000 – $32,000 (composite) |
(Costs above include basic railings and stairs for an attached, ground-level deck on a 1-story home. Prices will vary based on material choice and added features.)
As the table suggests, a small 200 sq. ft. platform deck might cost around $6k–$12k in wood, whereas a larger 400 sq. ft. deck could be in the $15k–$20k+ range for wood (or more if you choose higher-end materials). Upgrading to composite or PVC can roughly double the cost of a wood deck of the same size, but delivers longevity and lower upkeep. For example, a 20’×20’ (400 sq ft) composite deck might come in around $30k (vs. ~$15k-$20k for wood). Keep in mind these figures include the essentials – framing, decking, basic railing and stairs, and typical foundation posts – but not extravagant add-ons.
Design Complexity: Beyond square footage, the complexity of your deck’s design will also influence cost. Intricate shapes (octagons, curves, multiple levels) or deviations from a simple rectangular plan mean more labor and materials waste. Every extra corner, angle, or elevation change adds framing complexity and cuts into lumber that might otherwise be used efficiently. In short, simplicity saves money. A ground-level deck that is low enough to avoid requiring railing (<30″ high) can also save a substantial amount, since custom railing systems are expensive (more on that below).
Height (Ground-level vs. Elevated): The height of your deck is another key factor. A low platform deck close to grade doesn’t need long support posts or many stairs. But an elevated deck (for example, off a second-story or 4+ feet above ground) will require a sturdier support structure (beams, posts, deeper footings) and safety railings, which can increase overall costs by 20% to 50% compared to a ground-level deck. In Southeast Michigan, any deck attached to the house or above 30″ height must have railings by code and typically needs building permits and inspections for the structural posts. Deeper footings are also required – at least 42″ below grade to get below our frost line – so builders must dig substantial holes and pour concrete footing piers that won’t heave during winter freezes. All of this adds labor and material, increasing costs especially for tall decks.
Cost of Common Deck Features and Add-Ons
Beyond the basic deck platform, you’ll likely want (or need) several features that add functionality and safety. Here’s a breakdown of typical design features and their costs in Southeast Michigan:
- Railings: If your deck is more than ~2½ feet off the ground, railings are required for safety. Even on low decks, many people choose railings for aesthetics or to define the space. Railing costs vary widely by material:
- Wood railings (pressure-treated or cedar) are the most affordable, roughly $20 – $40 per linear foot installed.
- Composite or metal railings (e.g. aluminum balusters with composite posts) offer greater durability and lower maintenance but cost around $100 – $250 per linear foot.
- Glass railings (tempered glass panels) provide unobstructed views but are premium-priced at about $250 – $350 per linear foot.
- Wood railings (pressure-treated or cedar) are the most affordable, roughly $20 – $40 per linear foot installed.
- For context, a 12’x16’ deck might have ~50 linear feet of perimeter. Choosing composite railings over wood could add several thousand dollars to the project. Southeast Michigan homeowners often mix materials (e.g. wood posts with metal balusters) to balance looks and cost. Mitten Made Basements typically ensures any railing system meets Michigan’s building code (able to resist 200 lb lateral force) for safety.
- Stairs: Most decks require at least one set of stairs to ground level. A basic set of 3-4 steps (wood framing with decking treads) will usually be included in your deck estimate. However, longer or custom-width staircases add cost. As a rule of thumb:
- Wood stairs (with wood treads and risers) cost roughly $300 – $500 per step.
- Composite stairs (composite treads, often on wood frame) are about $600 – $800 per step.
- Premium PVC stairs can run $950 – $1,150 per step.
- Wood stairs (with wood treads and risers) cost roughly $300 – $500 per step.
- So a full flight of 10 steps in composite might add around $6,000-$8,000. If your deck design includes multiple levels or a wide split-staircase, expect costs to rise accordingly. Complex stair configurations (landings, turns) could add $5,000 – $10,000 or more to the project.
- Deck Lighting: Lighting extends the usability of your deck into the evening and adds ambiance and safety. There are budget-friendly options like simple solar post-cap lights or plug-in string lights for under $50 apiece, as well as integrated low-voltage LED systems. Basic deck lights (e.g. LED recessed step lights or post caps) might cost $30 – $50 each. If you opt for a full wired lighting plan – under-rail LED strips, stair lights, pergola lights, etc. – it can add several thousand dollars in materials and electrician’s labor. High-end integrated lighting packages can account for 5% to 15% of the project cost. To save money, consider installing conduit and junctions during construction so you can add more lighting later, or use solar lights that avoid wiring altogether.
- Pergolas and Shade Structures: Adding a pergola over your deck provides partial shade and a beautiful design element – essentially creating an outdoor room. In Southeast Michigan, a custom 12’ x 12’ cedar pergola costs around $9,000 installed (vinyl pergola about $10,000, and composite or high-end aluminum louvered pergolas can be $15,000 – $20,000 or more)【17†】. Prefab pergola kits are a cheaper option (you might find vinyl or aluminum kits for $4k–$6k, plus installation). Keep in mind that pergolas may require their own permits if attached to the house or of significant size. Mitten Made Basements has installed many pergolas and can advise on the best materials – cedar is popular for its natural look, while vinyl/PVC pergolas match composite decks and require less upkeep.
- Built-In Benches & Planters: Custom built-in seating or planter boxes on a deck are a great way to add functionality, but they do require extra labor and materials. A simple 6-foot built-in bench might add a few hundred dollars in wood and hardware, plus labor time. More elaborate seating arrangements (L-shaped corner benches with backs, storage benches) could run $1,000 – $2,000 extra when professionally built. Similarly, integrated planters or privacy screens will have material costs (wood or composite boards) and add to labor. If you’re on a tight budget, built-ins are an area you could potentially add later or do as a DIY project after the main deck is done. Nonetheless, if you want a seamless look, having them built with the deck ensures matching materials and a sturdy, code-compliant result.
- Other Add-Ons: There are virtually endless upgrades for decks, from built-in outdoor kitchens and fire pits to hot tub platforms, awnings, and more. Each will add costs – for example, a basic outdoor kitchen section for a grill could add $3k–$5k, and accommodating a hot tub might require special structural support and electrical work for several thousands more. These are beyond the scope of a standard deck project, but it’s wise to plan ahead. Even if you don’t install these immediately, design the deck structurally to handle future additions (e.g. extra bracing for a future hot tub, or dedicated space for a grill) if you anticipate them.
Labor and Permitting Costs in Southeast Michigan
Labor Costs: Labor typically makes up a sizable portion of your deck budget – often about 50% of the total project cost. In Southeast Michigan, where skilled contractors are in demand during the warm season, labor rates generally range from $10 – $22 per square foot of deck (this includes the entire crew’s work). For example, if your deck is quoted at $60 per sq ft total, roughly half ($30/sqft) is materials and the other half ($30/sqft) is labor and overhead. These labor costs cover everything from design and site prep (demolition, grading) to framing, decking installation, railing/stair construction, and final finishing. While you might find slightly lower labor rates in some rural areas, Greater Detroit/Ann Arbor area prices tend to cluster around the national averages for deck-building.
Choosing a local contractor with experience (like Mitten Made Basements) can actually save you money in the long run – professionals work efficiently, have the right tools, and are less likely to make costly mistakes. They also often get contractor bulk pricing on materials. A good builder will provide an all-inclusive quote up front that factors in labor, so you shouldn’t be surprised by extra labor fees halfway through. Always ensure any quote or contract specifies whether labor and clean-up is included.
Permits and Inspections: In Southeast Michigan, obtaining a building permit is required for new deck construction in virtually all municipalities. A permit ensures your deck plans meet the Michigan Residential Code for safety (proper footings, joist sizes, railing height, etc.) and usually includes a city/county inspector checking the work. Permit fees vary by locale and deck size – typically ranging from around $100 up to $300 for an average deck in many Detroit-area suburbs. In some cities the fee is a flat rate (e.g. ~$150), while others charge based on project value (often a set amount per $1,000 of estimated project cost). For example, one Michigan township’s schedule bases the fee on total material+labor value. As a general rule, budget a few hundred dollars for permits as part of your cost. (The Michigan state average range is broad – about $50 to $500+ for deck permits depending on location.) If your deck requires structural drawings or zoning variances (e.g. if building near a property line or over an easement), there could be additional administrative costs or a longer approval time.
Mitten Made Basements and other reputable contractors will usually handle the permit process for you, including filling applications and scheduling inspections, as part of their service. Inspection scheduling is important to keep the project on timeline – in Southeast Michigan, inspectors will typically check the post footings (holes) before concrete is poured, and then do a final inspection of the completed deck. These inspections are usually included in the permit fee. It’s crucial to comply with permits and inspections; building a deck without a permit can result in fines or an order to tear down the work – a nightmare scenario easily avoided by doing things the proper way.
Regional Considerations: Southeast Michigan’s climate and soil have some implications on labor and costs:
- Builders must dig deep footings (42″ minimum) due to frost line. This means more labor digging and more concrete, especially if the ground is rocky or has old tree roots.
- The construction season is mostly spring through fall. If you plan in winter, some contractors offer off-season discounts, but cold weather can slow down work (or require temporary enclosures/heaters to cure concrete).
- Local code specifics: Michigan requires all deck ledger boards (where the deck attaches to the house) to be properly bolted and flashed to prevent water infiltration. Labor to install flashing and galvanized hardware is standard, but critical, for our region’s heavy rains and snowmelt. Make sure your builder includes these code-required elements.
Cost Ranges for Common Deck Types & Sizes
Putting it all together, what do typical deck projects cost in Southeast Michigan? Here are a few scenario examples to illustrate common deck types and sizes:
- Basic Ground-Level Platform (200 sq ft): Imagine a 16’ x 12’ deck, just a couple feet off the ground, with one step down and no railing. Using pressure-treated wood, this might cost around $6,000–$8,000 installed. In composite, the same simple deck could be roughly $10,000+. This kind of deck is on the lower end of cost because it’s small and avoids extras (rails, lots of stairs). It’s a great budget-friendly option if your yard’s grade allows a low deck.
- Medium Elevated Deck (300 sq ft): A 15’ x 20’ deck attached to the back of a typical two-story home, about 3 feet off ground with a railing and stairs down to the yard. In cedar or pressure-treated lumber, expect maybe $12,000–$18,000 depending on railing style and site conditions. Upgrading that to composite could put it in the $18,000–$24,000 range. Adding a couple of nice extras – say, LED post-cap lights on the railing and a built-in bench – might add another $1,500+. Most suburban Michigan homes with decks fall in this category of size and cost.
- Large Multi-Level Deck (500+ sq ft): For instance, a 20’ x 30’ wraparound deck with an upper and lower level, multiple staircases, and a pergola. A project like this in premium materials can easily exceed $50,000. For example, a large 1,200 sq. ft. cedar deck was estimated around $62k–$65k in Michigan, while composite for that size was $78k–$81k. Every additional 100 sq ft adds significant cost, so large decks are a big investment. However, the cost per square foot often goes down on very large decks (because you gain efficiency in building a bigger platform). If you’re dreaming of a multi-tier outdoor entertaining space, be prepared for a wide cost range and make sure to get a detailed quote with all features itemized.
Keep in mind that these ranges are general. The lower end assumes a fairly simple design with economical choices, while the upper end includes upgraded materials and many add-ons. Southeast Michigan’s deck costs tend to align with national averages, though your exact quote will depend on your site and selections. We at Mitten Made Basements have built decks from as low as just a few thousand dollars (for a small ground-level platform) up to six-figure multi-faceted outdoor living projects – so there really is a huge spectrum. Most homeowners will land somewhere in the middle with a beautiful, functional deck that adds value and enjoyment to their home without breaking the bank.
Budgeting Tips: Save Money Without Sacrificing Quality
Building a deck is a significant investment, but there are savvy ways to save money while still getting a high-quality result. Here are some budgeting tips specifically geared for Michigan homeowners:
- Keep the Design Simple: Intricate shapes and multi-level layouts drive up labor costs quickly. Opting for a rectangular or square deck with straightforward angles will be far more cost-effective. Avoid curves, elaborate inlays, or odd angles unless they are essential to your vision. A simpler design doesn’t mean it won’t be beautiful – you can add interest with your décor and accessories rather than complex construction. As one Trex design guide notes, sticking to standard lumber lengths (8’, 12’, 16’ boards) also reduces waste and cuts costs.
- Choose Materials Wisely: You don’t always need to go for the most expensive material to get a great deck. Pressure-treated wood remains the cheapest upfront – you can always stain it in a modern color to elevate the look. If you desire low maintenance, consider composite for the decking surface and use wood for the framing and railings to save cost. This hybrid approach is common: the substructure is pressure-treated lumber (hidden from view), with composite deck boards on top for longevity. It gives you the durability where it counts but is cheaper than an all-composite build. Also, shop around different composite or PVC brands – for example, Trex has different product lines, and less costly composites or seasonal sales might be available. Sometimes last year’s color stock goes on discount.
- Build in the Off-Season: In Michigan, peak deck-building season is late spring and summer. If you plan your project for early spring or fall, you might get a slight discount or more flexible scheduling from contractors who are looking to fill their calendar. Some builders offer promotions in April or October, for instance. Just be mindful of weather – the build might take a bit longer if there are weather interruptions, but your deck will be ready to enjoy by the next summer.
- Do Prep or Finishing Work Yourself: Even if you hire a pro for the main construction, there are a few tasks you might handle yourself to save money. For example, demolishing an old deck (if you’re replacing one) – taking it apart and disposing of debris – could save a few hundred dollars in labor. If building in wood, you might stain or seal the deck yourself after construction is complete, rather than paying the contractor to do it. Only take on tasks you’re comfortable with – you don’t want to risk the quality of the build. But sweat equity on peripheral jobs (cleanup, painting pergola trim, installing your own solar lights after the deck is done, etc.) can trim the total cost.
- Plan for Future Add-Ons: If your budget is tight, prioritize the essentials now and leave luxury extras for later. It’s much cheaper to build a basic deck now and add features over time than to finance everything at once. For instance, you could have the contractor install the primary deck and railing, but hold off on the pergola or built-in benches. You might even design the deck with placeholders – e.g., have the footing foundations put in now for a future pergola, or design an easy way to add a staircase to a lower patio later. This phased approach lets you enjoy a functional deck immediately and upgrade it as your budget allows. Just ensure structural provisions are made for items like a hot tub or outdoor kitchen if you’ll add those down the line (it’s easier to add support beams now than retrofit later).
- Don’t Skimp on Structure & Safety: While saving money is important, there are areas where cutting costs isn’t worth it. Always use proper footings, hardware, and structural design as required by code – this is where a professional will not cut corners, and neither should you. Using galvanized or stainless steel connectors, lag bolts, and joist hangers may cost a bit more than nails, but they ensure your deck remains safe and sturdy for decades (especially given Michigan’s weather extremes). Similarly, invest in quality decking boards. For instance, a slightly higher-grade wood or composite that doesn’t warp will save you from replacements later. In short, allocate your budget to the bones of the deck and things that are hard to change later, and be more frugal with cosmetic choices. This strategy gives you a solid, long-lasting deck without surprise repair expenses.
Finally, always get multiple quotes from reputable local contractors. This will give you a sense of a fair price and also allow you to evaluate different ideas for cost-savings that one builder might suggest over another. Mitten Made Basements, for example, can provide value-engineering options – we might recommend adjusting the deck dimensions by a foot or two to align with standard lumber lengths (reducing waste), or suggest an alternate brand of composite that offers similar warranty at a lower cost. Little tweaks like this can add up to big savings without diminishing your deck’s quality or enjoyment.
Return on Investment: Resale Value and Long-Term Value
A new deck not only provides immediate enjoyment but can also increase your home’s resale value. However, the ROI (return on investment) can vary by material and market conditions. Here’s what to know about decks and home value in Southeast Michigan:
- Resale Value Impact: Historically, wood decks have offered one of the higher ROIs among home improvement projects. According to national data, a standard wood deck addition can recoup around 70–80% of its cost in resale value, whereas a composite deck tends to recoup around 60–70%. In fact, the 2024 Cost vs. Value Report showed a 16’ x 20’ wood deck costing ~$17,600 had an average 82.9% ROI at resale (recouping about $14,600). A similarly sized composite deck (cost ~$24,200) recouped about 68.2% (around $16,500 value added). This trend suggests that, while both types add value, the percentage return is a bit higher on the less expensive wood installation.
- Regional Note: In the Midwest and Detroit area, the ROI can be a bit lower in some years – past figures showed closer to ~50–65% ROI for wood decks regionally. But with the recent surge in demand for outdoor living spaces, Michigan homeowners are seeing stronger returns. A well-built deck is a major selling point for buyers looking to maximize outdoor enjoyment, which has boosted its value. Ultimately, if you plan to sell your home in the near future, a new deck could help attract buyers and potentially raise your selling price. Just don’t expect to get every dollar back – view a deck as partly an investment in your own enjoyment.
- Long-Term Value of Materials: ROI isn’t just about resale price – it’s also about the cost of ownership over time. This is where composite and PVC decks shine. Although a composite deck might initially cost 40-50% more than wood, remember that maintaining a wood deck can cost $450–$850 per year in upkeep, whereas composite is virtually maintenance-free. Over, say, 10 years, a wood deck owner might spend many weekends and thousands of dollars on staining, repairs and board replacements. A composite deck owner spends almost nothing on maintenance and enjoys a deck that looks nearly as good as new. If you plan to stay in your home long-term, these reduced maintenance costs and the longer lifespan of composites/PVC (often 2x that of wood) mean better long-term value despite the higher upfront price. It’s a classic pay-now-or-pay-later scenario.
- Enjoyment and Lifestyle ROI: It’s also worth noting the non-monetary return. A deck creates outdoor living space that can dramatically improve your quality of life at home. Southeast Michigan’s summers are perfect for barbeques, and a deck is an extension of your home for family gatherings or relaxing after work. Many homeowners find that the memories made on their deck – from summer cookouts to watching sunsets – are priceless. So even if you technically only recoup, say, 70% in resale dollars, the years of enjoyment are the remaining 30% (or more) in value to you. This “lifestyle ROI” is harder to quantify, but it’s a key reason so many Michigan homeowners decide a new deck is worth the cost.
In summary, a deck can modestly boost your home’s appraised value and marketability – especially if it’s a well-constructed, code-compliant deck that complements the house. Material choice will influence how much of the cost comes back at resale (wood decks currently have an edge in pure ROI percentage), but low-maintenance composites might appeal to some buyers as a selling feature too (no work needed to maintain). If resale is a primary concern, consult with a local realtor or builder; they might advise, for example, that spending extra on a fancy pergola won’t raise your sale price equivalently, but adding basic square footage or an attractive railing might. Mitten Made Basements’ design team often works with clients to strike the right balance – a deck that you love today and that will pay off when it comes time to sell your Michigan home in the future.
DIY vs. Professional Installation
You might be wondering if you could save money by building the deck yourself. It’s true that DIY deck building can eliminate the labor costs (roughly half the project cost, as noted) – potentially saving you several thousand dollars. However, there are important considerations and risks to weigh:
- Cost Savings: If you have the skills, tools, and time, DIY can indeed save a lot. For example, a $15,000 professional quote might break down to ~$7,500 materials and $7,500 labor. As a DIYer, you’d pay just the $7,500 for materials (perhaps a bit more, since contractors get bulk discounts) and your own labor is “free.” This is a big incentive – eliminating labor costs is the primary reason people consider DIY. There are also hybrid approaches: some handy homeowners act as their own general contractor, hiring out specialized tasks (like hiring an electrician for lighting or a contractor just to do the framing) while doing the rest themselves. This can save some labor expense while ensuring critical parts are done right.
- Skill and Safety: A deck is a major structural project. It might look straightforward on YouTube, but in reality it requires carpentry expertise – you’ll be measuring, cutting, and assembling a structure that must support thousands of pounds and keep your family safe. Mistakes can be dangerous. Common DIY errors include uneven or bouncy boards, inadequate foundation support leading to sagging, improperly attached railings or stairs, and not knowing the code requirements. Any part of a deck that’s defective or unsafe could cause injuries (a collapsed deck or a railing failure can be catastrophic). When you DIY, you assume all liability if something goes wrong. Professionals have the know-how to build it right and carry insurance for their work.
- Tools and Time: Building a deck from scratch demands a range of tools – from power saws and drills to post-hole diggers or augers, levels, wrenches for ledger bolts, etc. If you don’t own these, renting or buying will cut into your savings. And think about your time: a pro crew might build a 300 sq ft deck in a week or two. As a DIY weekend warrior, the same project might stretch over a whole summer (or longer) depending on your availability and help. Time is money too – consider the value of your weekends. Will you enjoy using your deck this summer, or spend it trying to finish construction?
- Permits and Code Compliance: Even as a DIYer, you are required to get permits and meet code. This means you need to produce plans that satisfy Michigan building code, and your work will be inspected. If you’re unfamiliar with the code, you’ll need to research or consult someone who is. Inspectors in Southeast Michigan will check critical details like proper footings, joist sizing, ledger attachment, and railing height/stability. If you fail an inspection, you’ll need to correct the issue (possibly rebuilding parts of the deck) before proceeding – which can be frustrating and costly. Professionals are well-versed in these requirements and typically sail through inspections. Pro tip: If DIYing, never skip the permit. As mentioned, unpermitted decks can cause huge problems when you go to sell the house or if an accident occurs.
- Quality of Work: A professional deck builder brings expertise and craftsmanship that can be hard for a first-timer to match. They know tricks to ensure the deck is square, how to neatly picture-frame composite decking, how to perfectly space balusters, etc. DIY decks, while done with good intentions, sometimes have a “home-made” look that could even hurt resale appeal if not done cleanly. On the other hand, a well-built deck by a pro will look solid and up to the standards of other professionally-built homes. If you’re a seasoned DIYer with carpentry experience, you might achieve great results – just be honest with yourself about your skill level for a project of this scale.
In summary, DIY installation can cut your out-of-pocket cost roughly in half, but it comes with significant risks and trade-offs. For many homeowners, the peace of mind and warranty that come with a professional installation are well worth the additional cost. Professional builders (like Mitten Made Basements) handle all the headaches – from design and permits to the heavy lifting and precise detailing – and you end up with a beautiful deck built to code and backed by a guarantee. If you do choose to DIY, consider having a consultation with a pro for guidance on the design and foundation; you might also hire an electrician for any electrical work (deck lighting or hot tub wiring must be to code). Always call Miss Dig 811 before digging post holes (utilities location service) and follow all safety precautions.
Many Michigan homeowners find a happy medium by hiring a professional for the core structure and doing smaller additions or maintenance themselves over time. For example, you could have a contractor build the primary deck and then you install your own low-voltage lighting kit afterward, or do the staining on your new cedar deck yourself once the wood dries out. This way, you know the deck is structurally sound, and you still save a bit by DIYing the simpler tasks.
Building a deck in Southeast Michigan can seem daunting with all these cost factors, but with the right planning and team in your corner, it’s absolutely achievable within a reasonable budget. We hope this guide has given you a clear breakdown of what to expect. Whether you opt for a modest wood platform or a sprawling composite oasis, your new deck will be a place to create memories for years to come. Mitten Made Basements is proud to have helped many local homeowners turn their deck dreams into reality – always balancing quality and cost-effectiveness for our Michigan climate.
