The chimney crown is the concrete or mortar cap that seals the top of the chimney structure around the flue opening. It is designed to shed water away from the brick and mortar below, but because it is fully exposed to freeze-thaw cycles, UV radiation, and thermal expansion, crowns are among the most commonly damaged chimney components. Even hairline cracks allow water to penetrate, accelerating deterioration of the underlying masonry and eventually causing costly structural damage inside and outside the home. Chimney Care Chimney Sweeps repairs damaged crowns and applies professional-grade elastomeric waterproofing sealants as both a restorative and preventive measure.
Minor crown cracks are addressed with flexible, paintable crown coat sealant that bonds permanently and moves with the masonry through seasonal temperature changes. Severely damaged or improperly built crowns — those with insufficient overhang, no drip edge, or crumbling mortar construction — are removed and rebuilt using proper portland cement mortar or pre-mixed crown coat, sloped away from the flue and overhanging the chimney face by at least 2.5 inches on all sides per NFPA 211 recommendations. After crown work is complete, we apply a vapor-permeable waterproofing sealant to the entire chimney surface to repel water while allowing trapped moisture to escape.
Ignoring a cracked crown is the leading cause of premature chimney deterioration in New England's harsh winters and Central Texas's dramatic weather swings. Contact Chimney Care Chimney Sweeps at +17742385550 or [email protected] to schedule a crown inspection and protect your investment.
