How much does it cost to build a deck?

Building a deck can cost anywhere between $4,500 and $9,500 on average nationwide. That's for a basic deck – pressure-treated wood, 150-300 square feet. For a more complex deck or one with higher-quality materials – hardwood or composite, multi-leveled, built-in features – you're looking at an investment of $16,000 to $24,000.

What affects the cost of building a deck?

As with most home improvement projects the answer is… it depends. The biggest influence on the cost of your deck will be the size, materials and labor. Design extras also affect the total cost of the project, but you can get a rough idea of what a new deck will cost you if you know those three things. Here's everything you need to consider.

  • Square footage: Obviously, the bigger the deck, the more it costs. A large structure takes longer to build and requires more decking, posts, piers, joists, and screws. Some deck contractors charge by the square foot as well, so if your budget is tight, lose some square footage from the design.
  • Elevation: How high off the ground will the deck be? Taller decks require stairs and railings. Stairs and railings add complexity – and material costs – to your project.
  • Labor: Deck installation contractors either charge by the hour or by the square-foot. Hourly rates include time spent including time spent sourcing materials, job set-up and break-down, etc.
  • Demolish an old deck: If there's an existing structure already in place, you'll have to factor some demolition costs into your new deck budget, or simply opt for a refinish. The cost to remove an old deck ranges anywhere from $500 to $2,000.
  • Permits: If you're building a new deck, you may need a permit. Your contractor can do this for you (for a fee) or you can apply yourself before the project begins. The average cost of a general building permit starts around $500, but can go much higher. Permitting fees vary from region to region and will depend upon the size and scale and value of the project.
  • Design extras: This is where it gets fun. Expensive, but fun. Go crazy. Add a hot tub. Or a pergola. Some garden boxes, a fire put, grilling area, built-in seating – all of it will cost you but remember, you can potentially recoup up to 70% of those costs in home resale value.

How much do deck materials cost (and what are my options)?

Pressure-treated wood is the most common, budget-friendly decking material. Hardwood and composite materials are for those with a higher price point. Here's a breakdown of material options and their national average cost:

Material

What is it?

What it costs

Pressure treated wood

Affordable and widely available, pressure treated wood is coated with preservatives to help it resist weather, termite and fungal damage. Treating the wood involves saturating it, which makes it prone to warping and splintering when it first dries. But if maintained properly once it's installed, it'll last you 20+ years.

$12-$18 per square foot

Plastic

Bugs and weather generally won't be a problem with vinyl decking, but it can get hot in the summer and some people don't like the look. Vinyl also might not be the bargain you'd expect. Plastic decking is in the middle, price-wise. The real advantage is you don't have to do much to maintain them. They're UV-resistant, require no sealers or finishes, and are free of splinters and cracks.

$13-$25 per square foot, depending on the brand

Softwood

When most people say “wood deck," they mean redwood or cedar. Both of these are considered softwood, but they're actually pretty durable considering how lightweight and easy they are to work with. They're also workable and stable, meaning they generally don't shrink or expand much due to weather.

$20-$35 per square foot

Hardwood

True to its name, tropical hardwood is denser than other woods and far more resistant to pests and decay. For example, ipe (pronounced “e-pay") can last 40+ years. But you'll pay extra for that durability. Hardwood comes from trees that tend to grow slowly and often has to be imported. Mahogany, teak and oak are all hardwoods.

$22-$35 per square foot

Composite wood

Wood fiber, plastic and a binding agent come together to form composite, a virtually indestructible mixed material that has pros and cons. It resists the elements well and requires less maintenance. But it also tends to be expensive, and some people find the look to be a bit, well, plastic.

$20-$40 per square foot, depending on the brand

How much does labor cost?

On average, nationally, contractors will charge $30-$35 per square foot. The cost for labor will be about two-thirds of your total budget. Deck installation professionals charge either by the hour or by the square-foot. Labor priced per square-foot is fairly straightforward.

Typically, building a new deck takes two to three weeks. A variety of factors can affect the timeline, mainly related to your yard:

  • How accessible is the location? Can the crew reach it easily?
  • Is there space near the construction site to store materials?
  • Does your yard have steep hills, big trees, or other landscaping challenges?
  • Do you have an old deck that needs to be demolished before putting the new deck in?
  • How's the weather? Are you building in a season where exceptionally cold, hot or rainy conditions might delay construction?

How can I save money on a new deck?

Besides shaving some square footage off your deck, you can also save money by using budget-friendly materials.

  • Railings: Cable railings are much more affordable than wood. They also improve visibility and look very modern.
  • Lumber lengths: Using standard dimensions (8', 10', 12' and 16' lengths) eliminates waste… and wasted money.
  • Protective coating: Saves money over time, preventing situations that require repairs.

Also think about joining forces with your friends and neighbors. If you're building similar decks at the same time, you could save by purchasing materials in bulk.

What are the benefits of adding a deck?

  • It's a lot cheaper than an addition. Adding a deck expands your living area at a lower cost per square foot than a structural addition. A basic deck costs about $30 per square foot. Compared to the national average cost for a home addition – up to $200 per square foot – that's a steal.
  • It increases your home value. Decks are consistently one of the improvements you can add to your home that will increase its value. Some homeowners will recoup 60-70% of their investment, when they choose to sell.
  • You get to enjoy it. Maybe even a hot tub too.
