Is it Safe to Put a Fire Table on Wooden Decking?

Thinking of popping a fire table on your wooden decking? Here's the short answer: yes, but only with the right safety measures in place. Wood and fire can be a risky pair, but with a little planning, they can coexist happily. Stick around to learn how to keep your deck safe, your fire roaring, and your marshmallows lightly toasted – not your floorboards.

Safety Considerations for Wooden Decking

If you've ever had the thought, "Will this set my deck on fire?" you're not alone. Fire tables are a great addition to any garden space, but when placed on timber, there are a few key risks to consider.

Fire Hazards

Combustibility of Wood

Let’s face it—wood burns. That’s what makes it great for bonfires, but not ideal as a foundation for open flames. Even treated decking boards are still flammable to some extent. Placing a fire table directly onto them without any buffer? You're asking for trouble.

Potential for Embers and Sparks

Ever sat around a fire pit and watched a spark take flight? Now imagine that spark landing on your beloved timber decking. Even if your fire table is gas-fuelled and doesn’t throw sparks, wind or carelessness can introduce other flammable materials. It only takes one stray ember to cause damage.

Heat Damage

Direct Heat from the Fire Table

Most fire tables generate heat from both the flame and the unit's base. If yours doesn’t have good insulation or elevation, the heat can transfer straight to the wood. Over time, that exposure can lead to gradual damage—or immediate scorching.

Potential for Scorching and Warping

Heat is sneaky. It might not cause problems right away, but frequent use can cause your decking to discolour, warp, or even crack. Think of it like leaving a hot pan on a wooden table for hours. Not pretty.

Protective Measures

So how do you protect your deck while still enjoying your fire table? Thankfully, there are simple, cost-effective fixes that can keep things safe and stylish.

Heat-Resistant Mats or Barriers

Materials like Concrete Pavers, Stone Slabs, or Specialised Mats

One of the easiest solutions is to place a protective layer between your fire table and the decking. You’ve got options here—concrete pavers, large stone tiles, or heat-resistant mats designed specifically for fire pits. These materials absorb and disperse heat, keeping it away from the wood.

Proper Sizing and Placement

Whatever you use, make sure it’s larger than the base of the fire table. You want a buffer zone that catches any stray embers and spreads the weight evenly. A good rule of thumb? Extend the protective surface at least 30cm beyond all sides of the table.

Clearance and Ventilation

Maintaining a Safe Distance from Combustible Materials

Keep your fire table away from anything that could catch fire—furniture, railings, even your outdoor rug. Three feet of clearance is a safe bet. This reduces the chance of heat damage and helps stop fires before they start.

Ensuring Adequate Ventilation

Fire needs air to burn cleanly. Make sure the area around and under the table is well ventilated. No squeezing it into corners or tight spots. Good airflow also prevents smoke from pooling around your guests.

Fire Table Design and Features

Not all fire tables are made the same. Some are far more suitable for wooden decking than others. Let’s look at a few smart design features that make a real difference.

Low-Profile Fire Tables

Reduced Heat Transfer to the Surface

Tables with a low-profile design often radiate less heat downwards. Many are built with insulation or air gaps underneath to reduce the risk of heat damage. If you’re buying new, look for one that’s specifically rated for use on wooden surfaces.

Built-in Safety Features

Flame Height Adjustment and Safety Shut-Off

Modern fire tables often come with controls to adjust flame height. This lets you manage how much heat is being produced. Many also include auto shut-off valves in case the flame goes out or someone knocks the table.

These little extras make a big difference—especially when kids or pets are around.

Maintenance and Monitoring

Even the safest setup needs a bit of TLC. Keeping an eye on your fire table and its surroundings can prevent accidents before they happen.

Regular Inspections

Checking for Damage or Wear

Give your fire table and decking a once-over before each use. Look for cracks, burns, or warping on the wood. Check the table’s gas lines and connections, and make sure any protective mats are still doing their job.

Fire Safety Precautions

Having a Fire Extinguisher or Water Source Nearby

No one wants to use a fire extinguisher, but you’ll be glad it’s there if things get out of hand. A large bucket of water or sand works too. Keep it close, just in case. And make sure guests know where it is.

Conclusion

So, is it safe to put a fire table on wooden decking? Absolutely—as long as you use the right precautions. With the right setup, you can enjoy cosy nights outside without risking your decking or your peace of mind. Just remember: a little prep goes a long way. And nothing spoils a night faster than an unplanned bonfire!

Now get the marshmallows ready—and fire it up, the safe way.
