Chimney Crown and Masonry Repair in San Antonio
Quick answer: Most chimney repairs fall into a few areas: the crown (the concrete slab that caps a masonry chimney), the mortar joints and brick, the damper, the smoke chamber and, on factory-built chimneys, the metal chase top. Small cracks are cheapest to fix early. Once water gets in, it wears away mortar, rusts dampers and can crack the flue liner.
Signs your chimney needs repair
- Cracks or crumbling in the chimney crown
- Missing, sandy or recessed mortar between bricks
- White, powdery stains on the brick (efflorescence), a sign that water is moving through the masonry
- Brick faces flaking or popping off (spalling)
- Water, rust stains or a musty smell in the fireplace after rain
- A damper that sticks, won’t close or has rusted through
- Pieces of tile or masonry falling into the firebox
- A rusted or sagging metal top on a siding-covered chimney

How do you know what repair my chimney needs?
Start with a chimney inspection. The national standard, NFPA 211, describes three inspection levels. A Level 1 inspection looks at the readily accessible parts of the chimney; a Level 2 inspection, usually with a video camera, is called for after a chimney fire, when you change the type of fireplace or fuel, or when a home is sold. The inspection tells you what’s damaged and what can wait.
Is it safe to use my fireplace with a cracked crown?
A cracked crown doesn’t usually make a fire unsafe right away, but it lets water into the chimney every time it rains, and that damage adds up. Have it repaired before small cracks turn into loose brick or a damaged flue liner.
Do you repair chimneys on historic homes?
Yes. On older homes, the mortar used for repairs should match the original, because mortar that is too hard can damage historic brick. If your home is in a San Antonio local historic district, exterior changes may need city approval; see our downtown San Antonio page for details.
