DIY vs. Hiring a Pro
Installing your own Trex decking can save you around 65% of the cost of hiring a professional to do it. If you don’t already have the necessary tools and equipment, budget an additional $500 to $1,000 to cover the costs for items such as personal protective equipment (PPE), a drill, a circular saw, hand tools, and a wheelbarrow.
Still, there are benefits to hiring a pro for this project, including the following:
Pros know how to prevent warping or movement when installing Trex decking.
Trex’s warranty may require professional installation.
Pros understand local building codes and permit rules.
They ensure your deck is properly supported.
Pros can complete the job in a few days—much faster than a DIY job.
Your deck will have a cleaner finish with professional labor.
You might DIY Trex decking installation in the following situations:
You have carpentry or construction experience.
The deck is one level, and it’s low to the ground.
You can obtain the necessary tools, and you know how to use them.
You understand the specific Trex installation instructions.
You’re familiar with permits and local codes.
Consider getting quotes from at least three local deck builders who can build the proper framing and support.
