Fireplace Repair in Sherman Oaks, Starting Where the Fire Hit Hardest

The firebox takes the heat first, so it shows damage first. In a masonry fireplace, the firebrick can spall, with the face flaking off, or crack through, and the joints between bricks can open. Small cracks in the firebrick are normal wear; open joints and missing faces are not, because they let heat into the common brick behind, which is not made for it. We cut out the damaged firebrick and set new brick in refractory mortar, the kind rated for direct fire. Ordinary mortar fails here within a season. In a factory-built fireplace, the walls are refractory panels made for that model. A panel cracked through, or one with pieces missing, gets replaced with the maker's part or one listed for the unit, not patched with a tube of cement and left.

The damper and smoke chamber come next. A cast iron damper that warped in a hot fire no longer seals, and one that rusted can seize. We replace the plate and frame where we can, or fit a top-sealing damper at the crown when the throat is too damaged to hold a new one. The smoke chamber, the sloped space above the damper, should be smooth. When heat breaks its parging away, the rough brick behind it collects creosote and can crack. Re-parging with a heat-rated mortar restores it.

Every fireplace repair in Sherman Oaks starts from a finding, an inspection photo or a note from a cleaning. The quote lists each part of the work and its price, in writing, before we begin. If the damage came from a chimney fire, we check that the flue above was cleared first, because a new firebox under a cracked liner does not make the fireplace safe. If you are making a claim, we photograph the damage before removal and keep the damaged panels or damper plate if your adjuster wants them.

Fresh refractory mortar needs time and a gentle start. After the repair, we tell you when the first fire can happen and how small it should be, usually a few low fires before a full one, so the new joints cure properly. You get photos of the finished work for the file. If the same damage returns, that tells us something else is wrong, such as burning with the damper partly closed or a draft problem, and we look at the cause rather than replacing the same brick twice.
