Reinforced cast-in-place concrete crowns with engineered drip edges and 100% vapor-permeable siloxane hydrophobic sealants to end freeze-thaw masonry destruction.
“Water penetration causes over 90% of all chimney masonry failures. A cracked crown acts like a funnel, pouring rainwater straight into your brickwork.”
The chimney crown is the horizontal concrete roof capping the entire chimney stack. Inferior mortar crowns crack within 2–3 seasons due to thermal expansion and freeze-thaw frost wedging.
We construct reinforced, fiber-dosed concrete crowns with 2-inch drip edge overhangs that channel water away from the masonry facade, followed by deep-penetrating siloxane repellents that keep liquid water out while letting trapped water vapor escape.
Siloxane and silane formulations penetrate up to 1/4-inch into brick capillaries, creating a molecular barrier that repels wind-driven rain while maintaining breathability.
Chipping away thin, cracked mortar washes to expose sound upper masonry courses.
Custom wooden forms built extending 2 inches beyond brick perimeter with stainless reinforcement.
High-strength 4,000 PSI fiber-mesh concrete poured and troweled with an outward watershed slope.
Pressure spraying full-depth breathable water repellent across all stack faces and mortar joints.
CSIA-certified expertise, video camera diagnostics, and uncompromising restoration standards.
