How Much Does A Deck Cost?

You’re thinking about making some changes to your backyard, and it’s time to start planning the project. You know that you’ll have to pay, but how much does a deck cost?

In this post we’ll review six deck projects that we’ve completed and discuss the budget range for each project. We’ll use real deck budgets for 2021 so you can get a good idea where your project might fit.

Watch the video version of this post below.

Okay, let’s dive into the first project!

Small deck

This deck is built with Deckorators composite decking. The short distance to the ground means this deck doesn’t require railing, which saves the homeowner quite a bit of money.

This project has a very simple shape, which makes the construction process go quickly. There is a small angle on one corner, but overall the installation crew won’t need to do much custom framing, cutting or assembly.

Being within 6 to 8 inches of the ground is considered a ground level deck. This deck doesn’t require the same level of footings and framing needed for a raised deck, which reduces the cost of materials and labor.

Small, ground-level decks like this one between 100-200 square feet normally have budgets between $5,000 – $10,000.

Mid-size ground-level deck

We built this project as a midway space between a raised concrete patio and a pool area. It’s perfect spot for a dining set or patio furniture. The simple rectangular shape, no railing, and some stair lights are the main contributors to the total cost for this deck.

For projects of similar size between 400-600 square feet, budgets between $18,000 – $25,000.

Mid-size elevated deck

Many of our projects are similar to this one, with an elevated deck surface, railing and stairs. In this case the homeowner chose glass railing, which provides more visibility than other options. With the large open space, this deck can function well for a combination of uses.

For similar projects 400 – 600 feet, a deck project budget is likely going to be between $30,000 – $40,000.

Large elevated deck

When you build a home on a slope to take advantage of the views, you give up access to the backyard. That’s where a project like this comes in – it provides additional living space on the main level, and it makes it easy to access the ground as well.

This deck is raised up off the ground 20 feet or more, which often requires engineering to make sure the structure is sound. While you can’t see them in this picture, this deck also requires some large underground footings to provide structural support. It’s also going to be permitted through your city or county, which adds to your timeline and cost.

On a large project like this that is over 1,000 square feet, budgets can be over $80,000 and can go up quickly with added features.

Large two-level deck

A popular option for many of our projects, this deck involves composite decking and aluminum picket railing. A recessed hot tub built into the deck allows for easy access, and a covered seating area beneath the upper deck is protected by a waterproofing system. This deck has ample space for entertaining, grilling, outdoor dining and personal relaxation.

As with the last one, this 1,000+ square foot deck cost is over $80,000.

Large multi-use deck

This large composite deck project provides ample outdoor living space.

A hot tub with a built-in access, a gas firepit, an outdoor kitchen with bar seating, and a spiral staircase are just a few of the features included in this deck. There’s even a TV built into the kitchen counter! Beneath the main deck, a hidden storage area works great for larger seasonal items.

Large, ambitious projects like this have budgets to match. While our large projects can start at $80,000, it’s not unusual to get well into the six figure range as you add cool features like these.


That’s the end of the tour! I hope these six projects gave you a good idea of what your deck might cost. If you’re ready to get a budget range for your project, send us the details.
