Chimney Crown Repair

Chimney Crown Repair Before & After - San Diego CA - Weststar Chimney Sweeps

At Weststar Chimney Sweeps, we want to help you avoid — or quickly get rid of — chimney leaks. They’re frustrating, damaging and, can turn a reliable chimney into an unsafe one.

Avoiding leaks means paying close attention to the parts of your chimney that were designed to help prevent leaks. From the roofline up, your chimney is particularly vulnerable to leaks, because that’s where your chimney is in direct contact with the elements. That’s why an array of protective parts are built into your chimney above the roofline – these protective parts are designed to direct water away from particularly water-susceptible areas.

  • At the very top of the flue, you should have a chimney cap keeping water from diving down into your chimney
  • Just below that cap, you should have a masonry or concrete chimney crown to divert water away from the flue opening, adding another layer of protection

Given the fact that the chimney crown is constantly in direct contact with the elements, it’s not uncommon for cracks to develop. And if left without repairs, these cracks can grow bigger and wider, allowing water to make its way into your chimney system and erode your masonry, damage your flue liner and degrade your chimney as a whole. This degradation process can happen faster than you might think — if water gets into small cracks in your chimney crown, it can freeze and expand with the changing temperatures, causing the crown masonry to crack and crumble.

When you call Weststar Chimney Sweeps to report a chimney leak, the chimney crown is one of the first places we’ll check, because it’s quite frequently the culprit. We’ll also check the crown for cracks during your annual chimney inspection – which means, if you’re keeping up to date with your inspections, there’s a far better chance that we’ll find damage before it degrades the chimney crown beyond repair. But whatever type of damage is found, Weststar Chimney Sweeps can give you a functional and effective crown.

Be It Minimal Or Extensive Crown Damage: Weststar Chimney Sweeps Can Help

Weststar Chimney Sweeps’ technicians will assess the extent of your chimney crown damage and recommend the most effective repair approach. You can count on us to be honest and thorough in our evaluation!

For Smaller, Less Extensive Cracks And Damage:
If we find hairline cracks that haven’t significantly damaged the integrity of your chimney crown, we can likely repair it and apply a water-repelling CrownCoat sealant that fills in cracks, protects your crown, and helps it do its job more thoroughly and efficiently.

For More Extensive Damage:
In certain cases, when water penetration and temperature changes have caused a crown with small cracks to turn into a crumbling, spalling trouble area, we may need to build a new chimney crown. If that’s the case, you can expect Weststar Chimney Sweeps’ experienced, CSIA-certified technicians to build a chimney crown that stands up to the elements, and provides your chimney with years of protection.
