Stop Crown Leaks For Good With C&C Chimney Crown Repairs & Rebuilds

Leaky, water-damaged masonry chimney? It could be an issue with your chimney crown. This cement top that sits over your chimney stack can crack, crumble, and allow water to pool and enter the chimney and home. Even a small hairline crack in a crown can eventually lead to hundreds or even thousands of dollars in water damage. But with our professional, reasonably priced crown repair and rebuild services, there’s no need to let things go that far.

What causes chimney crown damage and leaks?

First things first, typically crown damage is a result of the freeze/thaw process that happens when moisture expands and contracts during temperature shifts. This expansion and contraction leads to cracks on the outside of crowns and damage on the interior of crowns. If repairs aren’t made promptly, cracks and damage will only worsen with exposure to more moisture from the next rain.

But sometimes, crowns fail for another reason: poor design.

How do you know if your crown was poorly designed?

  • Is your crown at least 3 inches thick at its thinnest point?
  • Does your crown have a drip edge that extends at least 2 inches past your chimney stack?
  • Is your crown slightly sloped downward on each side?

If you answered “No” to any of the questions above, your crown could probably use a rebuild.

Why? A long-lasting crown needs to be made of quality concrete and should be of the right thickness so that water doesn’t wear through. Likewise, it should be slightly sloped and should have a drip edge to ensure that water rolls off of the crown and away from the masonry chimney stack and flashing. If the crown isn’t made to these specifications, chimney leaks are somewhat inevitable.

What is CrownCoat and how does it work to repair crowns?

CrownCoat is a brushable sealant that seals small cracks and provides a waterproof membrane across the entire crown area. This product remains permanently flexible, cures quickly (we’re talking 2-4 hours!), and protects the crown against leaks for 15 years! That’s a long time to not have to worry! And since it’s environmentally friendly, you won’t have to worry about the environment, either.
