How much does a deck cost?

The cost of a new deck depends on much more than the boards. From substructure and railing to labor and the features you choose, let's break down the factors that influence your total project cost. Use it to build a realistic budget, and understand what to expect before you talk to a contractor.

These are estimated total project costs — materials, labor, and substructure combined. Only a contractor can give you an accurate quote for your project.

Starting point: $10,000 - $30,000

Small to mid-size composite or PVC deck, simple rectangular layout, standard substructure, minimal features.

Mid-range: $30,000 - $60,000

Larger composite or PVC deck that is single level, with railing and stairs, standard substructure, and a few upgrades.

Premium: $60,000 - $100,000

Large deck with premium materials, multi-level layout, full railing, lighting, pergola or shade structure, standard or aluminum substructure.

High-end: $100,000+

Custom, multi-level builds with premium PVC decking, aluminum substructure, and high-end add-ons like built-in kitchens, hot tubs, pergolas, and premium lighting.

What makes up the cost of a deck?

Whether you’re building with composite, PVC, or traditional wood decking, the cost breakdown generally remains the same. Labor and the substructure make up the majority of the total cost. If you choose wood decking, you’ll also need to account for ongoing maintenance and repair costs beyond the initial project.

4 key factors that impact your deck cost

Deck size & material

Your deck budget is anchored by the dimensions you set and the materials you choose. A larger deck requires more materials and labor, while your decking material choice effects both upfront and long-term maintenance costs.

Design & add-ons

A simple, ground-level, rectangular deck is the most cost-efficient build. Going beyond a basic layout — adding elevation, multiple levels, or custom patterns — increases costs. Add-ons like railing, lighting, and built-in seating also add to the total.

Substructure

The frame beneath your deck typically makes up 35% or more of total project cost depending on the framing material. Replacing an existing deck can reduce this significantly if the substructure is still in good shape.

Location & labor rates

Contractor rates can vary 30–50% by region, and local permits can add $500–$2,000 to your project. Getting a quote from a local contractor is the only way to know what your project will truly cost.

Composite vs. wood decking: 25-year cost comparison

Upgrading from pressure-treated wood to TimberTech Advanced PVC or Composite adds as little as 15% to your total project cost — even though the boards themselves cost 20–40% more. That's because labor and substructure make up the majority of any deck build, regardless of what material you choose. Over 25 years, the savings become even more apparent: No costly sanding, staining, or sealing.

Cost of a wooden deck, ipe deck, and TimberTech deck over the years graph: An ipe or pressure-treated wood deck costs more upfront and more to maintain in the long run. While a wood deck might cost less initially, the annual maintenance costs add up quickly - plus, it will likely need to be replaced in about 10-15 years.

Deck Cost FAQ

Is composite decking more expensive than traditional wood decking?

Composite decking may have a higher upfront cost compared to traditional wood decking. However, over time, the lower maintenance requirements and longer lifespan of composite decking often make it a more cost-effective option. In the long run, you’ll save on maintenance, repairs, and replacements.

What is the cost difference between PVC and composite decking?

PVC and composite decking are both premium alternatives to wood, and their price points often overlap — but PVC generally sits at the higher end of the range. The difference comes down to material composition: Composite boards blend wood fiber and plastic, while PVC is made entirely of virgin and recycled plastic, making it more resistant to moisture, mold, and fading over time. TimberTech Composite collections start at a more accessible price point while TimberTech Advanced PVC collections like Vintage and Landmark sit at the premium tier — though both offer significantly lower long-term maintenance costs than wood.

What is the best deck material for long-term costs?

Long term, PVC and composite decking tend to be the most cost effective. Although they may have a higher initial cost, the low maintenance requirements mean you’ll spend less money and effort on upkeep. Materials like TimberTech are durable, reducing the need for frequent repairs or replacements. While pressure-treated wood is cheaper upfront, the long-term maintenance and repair costs can add up. Plus, it doesn’t deliver the same aesthetics as more premium options.

Does a deck add value to a home?

A deck is one of the more reliable outdoor improvements for home resale value. It adds usable square footage and increases curb appeal — both of which matter to buyers. While the exact return on investment varies by region, deck size, and materials used, composite and PVC decking tend to perform better than wood at resale because buyers recognize the lower maintenance burden. A well-built deck with quality materials like composite or PVC can recoup a meaningful portion of its cost while improving how you use and enjoy your home in the years before you sell.

How much of the total deck cost is labor vs. materials?

Labor and substructure make up the majority of any deck build — typically around 80% of your total project cost regardless of what decking material you choose. Based on industry averages, substructure material and labor accounts for roughly 38% of total cost, decking and railing labor around 30%, railing material around 12%, and decking material and fasteners around 20%. This is why your choice of decking has less impact on your total budget than most homeowners expect — and why investing in a higher-quality material like composite or PVC adds relatively little to the overall project cost.

How to budget for a deck project?

Start by understanding that your total deck cost is made up of more than just materials — labor, substructure, railing, lighting, and permits all factor in. A realistic budget starts with your deck size and desired features, then accounts for your region since contractor rates can vary 30–50% depending on where you live. Browse real completed projects to understand what builds in your area actually cost and then get quotes from at least two or three local contractors before committing to a number. No online tool can replace a contractor quote — it's the only way to get an accurate estimate for your specific project.

What factors affect the cost of building a deck the most?

The four biggest drivers of deck cost are size and materials, design complexity, substructure, and location. A larger deck requires more materials and labor, and your choice of decking material affects both upfront cost and long-term maintenance. Going beyond a simple ground-level rectangular layout — adding elevation, multiple levels, stairs, or custom patterns — increases cost meaningfully, as do add-ons like railing, lighting, and built-in features. The substructure alone typically accounts for 35–40% of total project cost, and contractor rates can vary 30–50% by region, making location one of the most significant variables in your final number.

Are there additional costs for permits when building a deck?

Yes — most deck projects require a building permit, and that cost should be factored into your budget from the start. Permit fees typically range from $500–$2,000 depending on your municipality, the size of your deck, and the complexity of the build. Requirements vary significantly by location, so it's worth checking with your local building department or asking your contractor early in the planning process. A reputable contractor will be familiar with local permitting requirements and can help you navigate the process as part of your project.
