Leaky Chimney? It May Be Time For A Little Crown Repair Or A Rebuild

Finding out you have a leaky chimney is never comforting, but if you live in Montgomery County, MD or a neighboring area of Frederick County or Howard County, you can take comfort in the fact that Traditions Chimney Sweeps is here to help you out. We specialize in leak investigation and repair, and our team is certified, trained, and equipped to address any problem area, including your chimney crown.

This area of the chimney, which is at the very top of the chimney stack, often cracks, flakes, and crumbles as a result of water erosion from rain, snow, sleet, and ice. A process known as the freeze/thaw cycle (which involves the expansion of moisture in the crown when temperatures outside change) can also break up the crown and lead to destruction and damage. And unfortunately, if repairs aren’t made and these cracks and crumbling areas aren’t filled and sealed, moisture can make its way down into the rest of the chimney as well.

Here at Traditions Chimney Sweeps, we know just how common crown damage is and how important repairs are, which is why we encourage our customers to call on us for their annual chimney inspections. During an inspection, we’ll look closely at the crown and determine whether or not any damage is present or any steps need to be taken to protect it and prevent leaks and damage. And if we do find cracks and damage, we can make repairs fast and effectively using CrownSaver or CrownSeal.

CrownSaver & CrownSeal — The Solution To Cracked, Weathered Chimney Crowns

We know our crown repairs will be effective and long lasting because our technicians use premier products from ChimneySaver:

CrownSaver is a cement hybrid product that’s been trusted by chimney professionals since the 80s. This product is applied over flashing at about 1/2” thickness and provides 10 years of leak protection with its waterproof barrier. It can be used to fix cracks and other crown imperfections.

CrownSeal is a elastomeric product that can be colored with mortar dye to match crowns of all shades. When applied, the product fills cracks and voids and waterproofs the crown surface, providing 10 years of guaranteed water protection. And because it remains permanently flexible, you don’t have to worry about it cracking as a result of the freeze/thaw cycle. Plus, it’s environmentally friendly!

Need A Full Rebuild? You Can Count On Our Certified Team To Do It Right

If your crown is failing because of more serious damage, we may recommend that you have your crown removed and replaced. The good news is: when you have your crown rebuilt by Traditions Chimney Sweeps, you can be confident it will last and last. We follow industry standards for crown design and construction and make sure our crowns are built of high-quality, durable materials and shaped and constructed to weather the rain, snow, sleet, hail, and ice that we sometimes get here in Maryland.

Once your chimney crown is repaired or rebuilt, we can waterproof it for greater protection and longevity using CrownCoat or CrownSeal. These waterproof coatings are designed specifically for chimney crowns and can provide years of protection against leaks, water damage, and freeze/thaw damage.
