Chimney Sweeps

Waterproofing

The effects of the weather on chimneys is staggering, specifically the effects of water. Water may be the greatest and most pervasive enemy of the bricks and mortar that make up a masonry chimney. Coffman's Chimney Sweeps can help you prevent damage to your chimney. All you need to do is have your Chimney treated with ChimneySaver. This is a world class waterproofing system. It is guaranteed to keep water at bay for 10 years. Have your chimney waterproofed soon, and protect it from the rains.

Crown Repair

Most masonry chimney crowns are constructed of common mortar, which is not designed for nor will it withstand weather abuse. Most mortar crowns crack immediately allowing water penetration and damage to your chimney. We can repair most crowns with CrownCoat, a flexible waterproof sealant that is applied over the entire chimney crown.

Tuck-pointing

Deteriorated mortar joints are entry spots for water. The most effective repair for deteriorated mortar joins is the tuck-point process. Your existing mortar is cut out to appropriate depth and repacked with new mortar. The joint is then formed with a concave surface that will direct water out of the joint.

Flashing

In time even the best flashing job deteriorates and fails with age and weather. We use FlashSeal which is a versatile repair system that, when dry, forms a flexible waterproof membrane. It’s formulated for permanent adhesion to asphalt shingles, metal flashings, brick, and other chimney and roofing materials, even skylights! FlashSeal is like installing a rubber boot at the base of the chimney.
