Keep Your Chimney Protected & Free Of Water With Professional Crown Repair Services

Most homeowners don’t spend much time thinking about the cement slab that sits at the top of their chimney stack – and to be fair, you shouldn’t have to. If your crown was properly constructed and is maintained and inspected on an annual basis, you shouldn’t have to worry about whether your crown is doing its job of keeping moisture out of your chimney. But what is there to worry about?

Because the crown of the chimney is constantly fighting off the elements, moisture, sun, and freeze/thaw cycles can cause any crown to crack and crumble over time – and this is especially true for crowns that weren’t built up to snuff. Naturally, if the crown is cracking or crumbling, it won’t be able to effectively keep moisture from entering the chimney system and causing damage.

What Makes A Good Crown?

You see, a lot goes into making a high-quality, long-lasting, and effective crown, and if the individual or team building the crown is inexperienced or uneducated, the results will be sub-par. Regular mortar mix will not be able to stand up to the beatings that a crown takes, year in and year out, which is why a well-made crown will be built of cement and mesh reinforcements. Both materials help ensure strong and durable results.

But it’s not just material that matters – a quality crown should be thick enough to resist corrosion and wearing through. If it’s to last, the chimney crown should be at least 3 inches thick at its thinnest point. And lastly, in order to be effective at directing water away from the flashing and chimney stack, the crown should have a slight slope and an overhang of at least 2 inches on every side.

How Can Damaged Crowns Be Restored?

If your chimney crown was improperly built, the team of experienced professionals here at Chimney Doctors of Colorado can build you a quality crown that will provide years of effective service. But if your crown is in relatively good condition and is simply cracking in a few places, we can make repairs using ChimneySaver’s CrownSeal  and CrownCoat products.

CrownSeal is designed to repair cracks and prevent them from growing and expanding. As the name implies, the product seals the cracks and provides a waterproof, flexible membrane for added protection. CrownSeal is a great option for crowns that are still in great condition structurally but are beginning to crack here and there.

CrownCoat, on the other hand, is a water-repelling product that coats the crown and protects it against water intrusion and water damage. If you’re looking to extend the service life of your crown and safeguard it against future damage, CrownCoat is the product to use.
