Firebox Repair & Installation

The firebox is the interior space in your fireplace where the wood is burned. Most fireboxes are made with firebricks held together by refractory mortar. Refractory mortar is built to withstand high temperatures, which is a critical feature in a firebox. Unfortunately, many fireboxes are not built using this mortar. This is why you see many fireboxes that have damage to the joints between the bricks.

Firebox Wear and Tear

Like any appliance, your firebox will start to wear out with use and time. That’s why it’s so important to have your firebox inspected each year, as recommended by the National Fire Protection Association. The heating and cooling that comes from burning wood in your firebox will cause the mortar between the firebricks to crack. As large chunks of the mortar falls out, this leaves gaps in the firebricks that can make your firebox unsafe to use. Hot gases can escape into these gaps and start a fire in your home.


If the bricks in your firebox are in good shape, but the mortar is starting to break down, your firebox is in need of tuck pointing. In this process, we remove the existing mortar and repack the space between the bricks with high-temperature refractory mortar.
