Cost to Build A Deck

As you can see above, the average cost to build a deck hovers around $6,200. However, depending on the size or scope of your project, the total price can bulge up to $14,000. 

We will get into all cost factors below, but in general, if you want to lower the cost of your deck installation, try to build it yourself, use cheaper materials such as Ipe or cedar and limit the custom upgrades like built-ins, fireplaces and so forth.

Building A Deck Cost Factors

There are plenty of reasons why certain decks are much cheaper than others. Those factors include:

  • Materials
  • Design
  • Railings
  • Built-in Features
  • Removal of Old Deck
  • Permits & Insurance
  • Hiring A Pro
  • Longevity

Cost of Materials 

The material you choose for your deck will play a major role in your deck installation cost. As you can see on our decks and porches cost estimator, prices go from as little as $1/sf to as high as $41/sf.

You could also go with plastic wood, vinyl, aluminum or concrete. All three offer their own set of advantages and price points.


Simple decks result in simple cost. Complex deck designs increase the cost. Most professional deck builders will offer architectural design services in addition to providing pre-selected plans. If you're looking for something simple, such as a square or rectangle deck, a pre-selected plan might be best, and these options often come with specific price tags that are dependent upon the wood you would like the deck to be constructed from.

If you choose to customize your deck, however, your costs will likely go up, and this is especially true when your builder uses premium materials. Some custom decks that are built by professionals can cost as much as $8,000 or higher while pre-selected decks may be as low as $1,500. When thinking about a deck design, you'll also want to consider your long-term plans to stay in your current home.


If you choose to build a raised deck, you’ll need rails. After all, safety first. To no surprise, rails add to the overall cost of the project. Therefore, if you install a heightened deck, expect the overall cost to rise due to rails as well as additional materials. 

Built-in Features

Upgrades that you do not need, but would nonetheless amplify your deck will of course raise the overall deck installation cost. Whether you go with a custom Jacuzzi, a cover, a built-in fireplace or a full outdoor kitchen, all additions come with a price. So, if you are trying to cut costs, curb your imagination just a bit.

Removal of Old Deck

Removing an old deck is not easy and as such, pros charge a pretty penny to get the job done. You can do it yourself, but if you pay a pro, expect to pay roughly $1,250.

Permits & Insurance

Many municipalities require permits for a new deck. Furthermore, some insurance companies will raise your homeowner’s insurance once the deck is installed. As such, you must research all permit and insurance prices in your city.

Price to Hire A Pro

After materials, the biggest cost factor will be whether or not you hire a professional to build your deck. As you can see in the graph above, the cost will likely hover around $6,000. This is the price if you hire a pro. If you DIY, the only costs are materials and your time. Depending on how you value your time, the cost to build a deck by yourself should not exceed $3,000.


A deck is not a set it and forget it type of addition. Deck repairs and maintenance will be necessary, but some deck materials require less attention than others. As such, durable deck materials, such as teak or redwood, will cost more.

Deck Material Costs

Fortunately, there are plenty of options when it comes to deck materials. There is a perfect deck material out there for every homeowner with any budget in any location.

See the most common deck materials below, along with their price. Keep in mind, this is just the price of the actual material. Installation is not included. For more insight into each one, please click their name.

Deck Covers

If you don’t live on the West Coast, chances are, you can’t use your deck for at least a third of the year unless you install a deck cover. When it comes to deck covers, you can either install an awning with screen or opt for full deck or patio enclosure (roof included). 

To no surprise, deck enclosures are much more expensive. While awnings typically cost $2,000, full roof enclosures run closer to $14,000. Nevertheless, both radically increase the amount of time you can spend on your porch. Furthermore, patio and deck enclosures protect you and your deck from inclement weather, bugs, debris and much more.

DIY or Hire A Pro

A professional architect or deck builder will be able to assist you in finding affordable options that can add value and significant curb appeal to your property. Hiring a professional to build your deck may cost more than doing it on your own, but it means that you won't have to do the work yourself or put in the time. In addition, having a professional deck builder handle your project can give you peace of mind in knowing that your deck is built properly and safely. Regarding the cost of materials, some deck contractors are able to get discounts on lumber and other building supplies because they buy in bulk. This means that your material costs may also go down compared to attempting such a project on your own.
