When to replace firebricks

Be careful - Replacing fire bricks can be tricky!

If you believe your fire bricks need replacing, source new ones, book a sweep and we'll fit them for free!

Firebricks in a stove reflect the heat back into the fire, which allows for a hotter, cleaner burn. But these are wear items and will need replacement from time to time.

Example 1: Cracked but okay

If a brick is well supported on three edges, it can remain in place.

Example 2: Hairline cracked but okay

As a rule of thumb, a single hairline crack is not a problem.

Example 3: 'Could fall into the fire', replace

If it looks like it could fall into the fire, replace it!

Example 4: 'Can see the stove wall', replace

If you can see the stove wall behind the brick, replace it!
