The number of homes being built with a deck is declining, with less than 20% of new construction started in 2020 having one. This is down from 27% in 2007 and 2008. 

If you don’t have a deck but decide you want one, you’ll want to know more about deck installation costs. We’re here to help.

Read on to learn more about building a deck and how much it costs. 

How Much Does a Deck Cost on Average?

With so many factors affecting the price of installing a deck, the national average is quite a large range. For example, some homeowners spend as little as $2,500 on building a residential deck. 

Others may spend as much as $20,000!

So it’s safe to say you need at least a couple of thousand dollars to complete the project, but it’s better to budget more, especially if you want to customize your deck.

Factors That Affect the Cost of a Deck Installation

Some of the most apparent cost factors include the deck size and decking materials. But, aside from deck size, the design can also increase the price.

For example, a wrap-around deck from the front porch to the side of the house will cost more. Installing a second-story deck could double the price. Adding deck railings and columns or stairs will cost more too. 

A small but elaborate deck will have a higher price than a standard medium-sized deck. With so many add-ons to consider, the cost of your deck can quickly increase. Some add-ons you might want include:

  • Built-in seating
  • An enclosure
  • A firepit
  • Planter boxes

When it comes to decking materials, there are three standard options. They are:

  • Wood
  • Composite
  • Plastic

Of course, some materials cost more than others. However, you could spend three or four times as much if you choose one over another. A deck specialist can help you determine the best material to use for your home that fits within your budget.

Aside from these glaring cost factors, there are still others to consider. 


A standard deck requires concrete deck blocking.

But if you plan on installing additional weight, like a hot tub, your deck will need support structures with concrete footings. Raised decks also need extra support beams and footings. Naturally, this will increase the price.

Labor and Permits

For any construction project, you need to factor in labor costs. One way to identify these costs is to follow the 50/50 rule. For every dollar you spend on materials, expect to spend another dollar on installation. 

This can help you estimate how much labor will be. Also, keep in mind that labor costs vary by state and city. You can research standard labor costs in your area online. 

Building a deck will usually require a permit. Check with your local government to see the exact requirements and fees. 

Demolition and Removal

If you already have a deck, you’ll need to pay for the workers to demolish and remove it before building the new deck. This is often between $5 and $15 per square foot. 

Build Your Dream Deck

It isn’t easy to estimate the cost of a deck installation without considering all the factors mentioned in this article.

Start by sketching what you want your deck to look like, then research how much it will cost in your area. Finally, make a budget for your deck so you don’t spend more than you can afford.
