CHIMNEY CROWN REPAIR IN DALLAS, TX
The crown is the concrete slab across the top of the chimney, and in Dallas it is the most sun-exposed surface on the entire house. Flat, horizontal, and facing straight up at a Texas summer — concrete responds by crazing into a fine web of surface cracks, then opening those cracks a little wider with every hundred-degree afternoon. There is no snow load here, but there does not need to be. UV alone will finish a crown.
Then the storms arrive. A crazed crown that would shed a gentle rain takes wind-driven water straight down into the masonry, which is why the leak calls cluster in spring. Brown Chimney measures every crown on site, because price follows the actual dimensions. Cracks on a sound crown are cleaned, patched, and sealed. A crown that has failed through gets rebuilt with a one-inch minimum drip-edge overhang, no exceptions. Crown sealing on an intact crown runs $249–$875 as preventive maintenance — and in this climate it is genuinely preventive.
