How Much Does It Cost to Build a Composite Deck?
A composite deck, like a lot of other home improvement components, makes a home more valuable. It also transforms unused spaces of your property into useful ones.
However, building the right composite deck isn’t as easy as you think. To build a safe and durable composite wood, individuals should use a suitable decking board. But, this board itself only accounts for 1/3 of the total costs you’ll spend on your composite deck.
Often, some people opt for low-quality wood, which is a bit cheaper upfront. However, with time, you’ll end up paying more on maintenance and in some cases, even replacements as the wood can easily rot or get infested by termites.
How much money you use building your composite deck depends on your deck size, how complicated its design is, the quality of materials you use, and if you’ll incorporate special features like fire-resistant boards.

The Thickness of the Boards- thicker boards are more durable than lighter ones. But, they are also more costly. Rather than opting for 24mm thickness boards, choose the ones of 25mm thickness, for durability purposes.
Fixings- most installers use a hidden fastening system when building a composite decking. This system fastens the installation process by 60% compared to wooden boards. You can save money on fixings by purchasing your boards from companies that offer them free of charge.
Maintenance– when calculating the total cost of your deck, think about its life cycle. Wood decking can rot and split, which means it’ll need regular repairs and replacements to preserve the structural integrity and appearance of your wood.
Design– complex designs are costlier as they have several levels, built-in grills, elaborate railings, etc. Also, if you’ll build your deck on a second story, it will cost more.
Tips and Options to Cut Down on Costs
If you’re budget-conscious, there are some steps you can take to reduce how much you spend. These include:
- Building your composite deck on your own.
- Hiring a composite deck installer during the off-peak season for affordable installation charges. Note that deck prices are mostly higher during the summer since the materials and contractors are usually in high demand. So try building yours in spring or fall.
- Instead of curved and complicated designs, go with straight decking as it is much cheaper.
- Take advantage of efficient features like outdoor storage to make more use out of your space.
- Incorporate creative designs that don’t up the cost. For instance, you can use a mix and match the color scheme.
- Get multiple quotes from different builders and compare the price in terms of quality.
