Every fire your fireplace burns puts its masonry through a punishing cycle of expansion and contraction, and over time that stress cracks brick and turns mortar to powder. Once joints open up, intense heat can reach parts of the home that were never meant to face it. Quick Chimney repairs and rebuilds firebox brick and mortar with materials made for direct flame, so the fireplace is ready to work the way it was built to.

Frequently asked questions
Why is the brick inside my fireplace cracking when the outside of the chimney looks fine?
The firebox lives a much harder life than the exterior stack. Each fire heats the masonry rapidly, the materials expand, and then everything contracts as it cools. Repeated over hundreds of fires, that movement opens hairline cracks in brick and slowly breaks down the mortar between them. It is normal wear for a working fireplace, but it does need to be repaired before the damage deepens.
Can I keep using my fireplace if the firebox has cracks or missing mortar?
It is safer to hold off until the damage is repaired. The firebox is the barrier between open flame and the structure of your home, and gaps in brick or mortar can let extreme heat reach material behind it. Having a technician evaluate the firebox first is the prudent move, and repairs are usually straightforward once the extent of the wear is known.
