Chimney Crown Repair
The Chimney Crown is the first line of defense against water intrusion into your chimney.
The crown is sloped to prevent rain and moisture from seeping into the masonry or the joint between the masonry and the chimney flue. Concrete will expand and contract with the change in seasonal temperature, causing it to crack. Simple cracks can lead to water damage in several areas, including where the fireplace/chimney meets the ceiling or in the attic around the rafters.
When moisture penetrates the crown and gets inside the chimney, it can weaken the interior masonry resulting in more chimney repairs.
Most homeowners are unaware there is a problem until a chimney inspection is performed, or water stains become visible on the ceiling. Depending on the extent of the damage, a Certified Chimney Professional will need to either repair or rebuild the crown.
Process of Repairing the Chimney Crown
Although the chimney crown has a cement surface, it is not as durable as the brick masonry. Being on top of the chimney, the cement chimney crown is constantly exposed to rain and other weather conditions. This means that it will eventually fall victim to deterioration and develop small hairline cracks. Even though these cracks appear small, they will enlarge over time and result in a costly chimney crown replacement or water damage.
If the damage is not too severe, our technicians can fill in any surface cracks and apply an All-Weather CrownCoat to protect the chimney crown with a flexible, waterproof membrane.
We can even apply this sealant in below-freezing temperatures, so if your chimney crown cracks in the winter, we can fix it fast. It’s an environmentally friendly, water-based sealant and we offer a ten-year warranty.
Custom Full Coverage Chimney Caps
Our Certified Chimney Professionals recommend installing a full coverage chimney cap which covers and protects the entire top of the chimney. This Custom Chimney Cap is more like an umbrella protecting the whole top of the chimney against outside elements, shedding water away from the chimney and flashing.
