Pristine Sweeps Can Make Your Chimney Crown Strong Again

At Pristine Sweeps, we take great pride in our masonry work, and our masonry expertise includes outdoor fireplace construction, exterior home veneers and full chimney rebuilds. It also, of course, includes all types of chimney and fireplace repairs, like chimney crown repairs and rebuilds.

Why Is The Crown So Important?

The crown is one of your chimney system’s most important barriers against moisture intrusion. A properly-constructed and installed crown will divert water away from the flue opening and toward the gutters, without allowing it direct contact with the chimney masonry exterior. Since masonry crowns have to constantly battle the effects of the elements — from the heat of the sun to pounding rain and freezing snow — cracks and spalling can, and often do, develop.

Chimney crown damage quickly gets worse, too. Even small imperfections allow water greater access to the inside of the masonry, and the freeze/thaw process can then allow water to expand inside the crown, causing significant spalling damage. Having crown damage repaired quickly and correctly is key to minimizing further chimney damage and keeping leaks from reaching your home’s interior.

From Repairs To Rebuilds, Pristine Sweeps Can Help Your Crown

We most often find crown damage either during an annual chimney inspection or after a chimney leak develops. We certainly prefer the former, since it allows Pristine Sweeps’ technicians to make repairs while the damage is minimal, and before a full crown rebuild and potential interior repairs become necessary. That’s a part of why keeping up with annual inspections is so beneficial.

When we inspect your chimney crown for damage, we’ll recommend the best approach for bringing your chimney back to peak moisture protection.

ChimneySaver CrownCoat

If your crown has smaller cracks that haven’t developed into large gaps, we may be able to make adequate repairs by sealing the crown with CrownCoat. CrownCoat is a flexible waterproof sealant that covers cracks and protects both the crown and the flue’s interior from moisture intrusion.

Crown Rebuilds

If the damage to your crown is more considerable, we’ll have to make more significant repairs and may even need to do a full crown rebuild. If Pristine Sweeps does need to rebuild your crown, you can expect expert craftsmanship and meticulous attention to detail. We want your clean and new crown to look its best and be designed and built to withstand years of weather, while providing the protection you expect and need.
