How Much Does It Cost to Build a Deck?

Building a deck can be a valuable investment, adding usable outdoor living space and increasing your home’s appeal. On average, homeowners in the U.S. spend between $4,000 and $12,000 on a professionally built deck, with most projects falling around $7,500. Costs vary based on materials, size, design complexity, and local labor rates.

Below, we break down the cost of building a deck by material, labor, size, and style to help you budget for your project and choose the right setup for your home.

Average Deck Costs at a Glance

The cost of building a deck varies widely depending on your choices in materials and the overall design. A small, simple wood deck may cost just a few thousand dollars, while a large, multi-level composite deck can climb well over $20,000. Below is a table that outlines typical pricing ranges for different types of deck projects to give you a general idea of what to expect.

Factors That Affect Deck Building Costs

Several components go into the total cost of building a deck. The most influential include:

1. Deck Material Costs

Material selection is one of the biggest cost factors
for your deck. Basic pressure-treated lumber is affordable and widely available, but it requires more maintenance over time. On the other end of the spectrum, composite and PVC materials have a higher upfront cost but require very little upkeep and often come with long warranties. Your choice here should balance appearance, durability, and your long-term maintenance expectations.

The material you choose significantly impacts the overall price. Pressure-treated wood is the most budget-friendly, while composite and hardwoods tend to be more expensive but longer lasting.

Note: Composite and PVC options often have longer warranties and require less maintenance, which can offset upfront costs over time.

2. Labor and Installation Costs

Hiring a professional ensures your deck is safely and properly built, especially if it includes features like multi-levels, staircases, or built-in seating. Labor rates vary by region, but in general, installation costs account for more than half of your total project budget. DIY projects can save on labor but may take longer and require specialized tools or permits.

Labor typically makes up 50% to 60% of the total project cost. Depending on your location and the complexity of the deck, expect to pay $15 to $35 per square foot for professional installation.

3. Deck Size and Layout

Naturally, a bigger deck costs more. But the shape and complexity of the deck also influence cost. A basic rectangular platform is easier and cheaper to build than a curved or multi-tiered design. Features like multiple levels, built-in planters, and curved railings can elevate the style — and the price.

Larger decks cost more overall but may be more affordable per square foot due to economies of scale.

Complex layouts, multi-level designs, or built-in features like benches or lighting will raise costs.

4. Style and Custom Features

Want to add personality or functionality to your deck?
Custom upgrades can transform your outdoor space but also increase your overall spend. Stairs, decorative railings, integrated lighting, and shaded covers like pergolas all come with their own installation and material costs. Consider your lifestyle and how you’ll use the space before deciding which extras to include.

Add-ons like stairs, railings, pergolas, built-in seating, and lighting can significantly increase total cost.

Example Deck Projects and Pricing

To help visualize what your project might cost, here are some example deck builds with estimated pricing:

• A basic 10×10 wood deck made from pressure-treated lumber, with no railing or add-ons, typically costs around $4,000 to $5,500, including labor and materials.
• A 12×16 composite deck attached to the back of a home, with standard railings and a single set of stairs, can cost between $7,500 and $11,000, depending on your location.
• A large, two-level cedar deck with custom railings, built-in seating, and lighting may cost $14,000 to $20,000+ depending on square footage and extras.

These examples are averages — your final price will depend on the specific materials, features, and site conditions involved.

Additional Cost Considerations

• Permits & Inspections: Some cities require permits for deck installation. Fees typically range from $100 to $500.
• Demolition of Old Decks: Removing an existing deck can add $500 to $2,000 depending on size and disposal fees.
• Foundation or Support Work: Sloped or uneven ground may require additional footings or structural work.

Is Building a Deck Worth It?

Building a deck is one of the most rewarding exterior upgrades you can make. Whether you want a small wood platform for casual gatherings or a multi-tiered composite retreat, knowing the cost breakdown by material, labor, and size can help you plan your project wisely.

To get an accurate quote for your area and design, it’s best to consult with local deck contractors. They can help you explore materials, handle permits, and create a customized plan that fits your budget and your backyard vision.
