Chimney Cap & Crown Repair

The chimney cap and crown are your chimney's first line of defense against the elements. San Antonio's occasional heavy rainfall and hail events can quickly erode an unprotected chimney crown — the mortar slab that seals the top of the chimney around the flue tile — leading to water infiltration, freeze-thaw cracking, and costly interior damage. Chimney Care Chimney Sweeps repairs cracked and deteriorated crowns using professional-grade elastomeric crown coatings and Portland cement mixes, and installs stainless steel and copper chimney caps to seal the flue opening against rain, wind-blown debris, and wildlife.

A properly fitted chimney cap serves multiple functions: it blocks rain from entering the flue, prevents birds, squirrels, and raccoons from nesting inside the chimney, and contains sparks that could otherwise land on your roof or yard. We carry single-flue caps, multi-flue caps, and full-coverage top-mount caps to fit virtually any chimney configuration. All caps are sized to the flue tile or liner diameter and secured to prevent wind displacement.

Crown repair is among the most cost-effective chimney maintenance investments available to San Antonio homeowners. Sealing a cracked crown early prevents water from reaching the brick and mortar below, where it can cause extensive spalling and structural damage that is far more expensive to correct. We apply high-build elastomeric coatings that flex with temperature changes and are warranted against cracking.
