How Much Does It Cost to Build a Composite Deck?

When it comes to any home improvement project, cost is a major consideration. Whether you’re looking to DIY your deck or hire a professional to build a deck for you, making sure you’re familiar with pricing and costs is a great place to start. So, how much does it cost to build a composite deck, anyway? Well, there are few things to consider.

The first thing to think about is the fact that composite decks last longer than traditional decks — up to 30 years, to be exact. Select brands, like MoistureShield, can last 50 years or even longer with proper installation and care. With that in mind, expect to pay more upfront for longevity and less in repairs and maintenance.

In the long run, you end up saving more with a composite deck because you avoid water damage and the recurring costs for sealant to prevent it. In addition, you save money and time saved by not having to sand, seal or stain your deck yearly.

Other Cost Considerations for Building a Composite Deck

There are four key things to consider when building a composite deck: size, shape, materials and labor. The size of your deck directly impacts how much material you’ll need as well as the amount of labor you’ll need. In short, the larger your deck, the more expensive it’ll be. As far as shape goes, square and rectangle options are simpler to build, and will be more affordable as a result. If you want a curved deck, keep in mind that substructures with complex metal frames and joists might be required and will come at an extra cost.

You should also consider a materials budget when building a composite deck. Substructure materials like lumber, hardware and concrete and surface materials like deckboards, railings and fasteners can all impact costs. A general starting point for material costs will be between $9-16 per square foot, including the structure, railing and more. After labor costs, composite deck costs can run upwards of $45-55 per square foot. Not sure what type of composite decking board you want to use yet? Use this handy guide to explore your options.

Of course, you can save on labor by making deck building a DIY project. However, hiring a contractor saves time and usually comes with a higher-quality finished deck. When you hire a contractor you don’t have to worry about buying equipment, knowing local building codes or figuring out the design. Save yourself the time and find the right contractor for your project.

Additional Factors to Consider

Do you plan on entertaining on your deck? Would you like a multi-level deck with or without stairs? What about a designated area for plants? These are all things to think about when designing your deck and considering deck cost. Seemingly small things like railings, a space for a grill or built-in seating can add up and add to the finished cost. To get an idea of what your deck could cost you, try our Deck Estimator tool.*

How To Save on Your Composite Deck Costs

Luckily, it is possible to save while building your composite deck. Start off by getting multiple quotes, looking for the right balance of price and quality. You could also start with your budget first and ask your contractor to build within that number, finding design modifications to reduce your quote. Finally, find the right timing. Deck prices typically peak in the summer when contractors and materials are in demand, so try a fall or spring build.
