Is it safe to put a fire pit on a Trex deck?

It is generally not recommended to place a fire pit directly on a Trex (composite) deck, as it can potentially cause damage or even be a fire hazard. Trex decking is made from a combination of wood fibers and plastic, and exposure to high temperatures or open flames could cause it to warp, melt, or even catch fire.

However, if you still want to enjoy a fire pit on your Trex deck, consider these precautions:

  1. Choose a fire pit specifically designed for use on decks: Some fire pits are designed with heat-resistant features, such as heat shields, to protect the surface beneath.
  2. Gas fire pits should only be used as long as they are rated safe for being placed on a deck.
  3. Never burn real wood as sparks and embers will certainly cause damage to your deck and could start your house on fire.
  4. Use a fire-resistant pad: Place a fire-resistant pad or mat under your fire pit to provide an additional layer of protection for your decking.
  5. Maintain a safe distance: Keep your fire pit at least 10-20 feet away from your home, other structures, and combustible materials.
  6. Follow local regulations and guidelines: Check with your local authorities for any restrictions or regulations regarding the use of fire pits on decks.
  7. Never leave the fire pit unattended: Keep a close eye on your fire pit, and make sure to fully extinguish it when not in use.

By taking these precautions, you can reduce the risk of damage or fire, but it’s important to remember that using a fire pit on a Trex deck still carries some risk. Always prioritize safety and carefully follow the manufacturer’s guidelines for both your fire pit and your decking materials. is a stocking Trex dealer and ships Trex Decking direct to your home or job site.
