CrownSeal/CrownCoat Water Repellent Protects Your Chimney

If we were to compare a chimney to a soldier vigilantly protecting your home, ChimneySaver Waterproofing might be its armor, and the combination of the chimney crown and chimney cap would form its helmet. Together, they work to keep the chimney safe against its worst enemy: water.

Your chimney crown is constructed out of masonry material, and like any other part of your masonry chimney, it’s made to be durable, but can sustain damage from water’s attacks.

We’ll most commonly see damage on a chimney crown in the form of cracks and holes, but we also see more extensive damage, including erosion and missing pieces. This damage seriously decreases your chimney’s ability to protect itself from water, and once water begins to make its way into the masonry structure, you can end up with damaged ceilings, walls, floors and masonry.

It’s important to repair a damaged chimney crown as soon as possible! Blue Sky Chimney Sweeps’ technicians are trained to provide proper chimney crown repair. We may be able to repair and protect your chimney crown using ChimneySaver’s CrownSeal or CrownCoat water protection products. We’ve found these to be highly effective and dependable products that not only rid your crown of the cracks and gaps that are leaving your system vulnerable, but also strongly protect the crown masonry from water going forward.

Why We Use ChimneySaver’s CrownSeal And CrownCoat Products

Sealers and silicone coatings that are not specifically designed for chimney masonry will form a water-resistant surface film, which will keep water out, but will also trap water vapors in. Since the vapors can’t escape through the masonry, they will contribute to spalling (flaking or chipping) masonry, scaling and deterioration, or worse, freeze-thaw damage (in which trapped water shrinks and expands, significantly damaging the masonry from the inside out).

ChimneySaver’s CrownSeal and CrownCoat penetrate and line masonry pores, rather than forming a film. These elastomeric coatings provide exceptional protection for your crown, curing to a natural concrete/mortar appearance.

Take a look at these before and after images showing a damaged chimney crown that was repaired and protected with CrownSeal:

BEFORE: A Blue Sky Chimney Sweeps customer contacted us with a chimney mortar crown that was cracked and deteriorating, leaving the chimney system susceptible to even more water damage.

AFTER: Blue Sky Chimney Sweeps applied CrownSeal to the damaged chimney crown to create a 10-year seal against rain and weather damage.

ChimneySaver’s CrownSeal and CrownCoat offer exceptional protection against water damage, and carry 10- and 15-year manufacturer’s warranties, respectively.

More Information On ChimneySaver’s CrownSeal And CrownCoat

CrownCoat
This is ChimneySaver’s brushable chimney crown waterproofing product, and our technicians apply it by patching cracks and other areas of damage, then using two coats of CrownCoat over the whole crown to create a waterproof membrane.

CrownSeal
ChimneySaver’s CrownSeal offers another option for chimney crown protection, which, like CrownCoat, forms a flexible waterproof membrane where it’s applied. We apply CrownSeal with a trowel and a brush, and can use it to turn a cracking crown into a smooth, well-protected barrier against chimney water damage.
