Professional Chimney Masonry Repair in Kissimmee

Yes. Brick and mortar soak up water like a sponge, and wind-driven rain can push moisture through porous brick or cracked mortar joints into the chimney. The water then shows up as stains on the ceiling, a damp firebox or white efflorescence. Repairing the joints first and then applying a breathable water repellent stops most of it.

Chimney bricks crumble when water keeps getting into them and pushes the face off, a condition called spalling. A cracked crown, a missing cap, hard modern mortar on soft old brick and paint or sealers that trap moisture all speed it up. Fixing the water source comes before replacing the damaged brick.

Chimney masonry repair starts by finding which brick and mortar joints have failed. Next the crew grinds out the loose mortar, replaces cracked or spalling bricks, and repoints the joints with a mortar matched to the old work. The crown and flashing are checked at the same time, since they decide how wet the masonry gets.

Chimney bricks can be sealed, but only with a breathable masonry water repellent and only after the mortar joints and cracks are repaired. A clear paint or film-forming sealer traps moisture inside the brick and causes spalling. A breathable product lets vapor out while keeping most rain from soaking in.
