Because chimneys venture above the roof line, they are vulnerable to environmental elements. Wind, storms and normal wear and tear cause cracking or lifting of sealant around the chimney, opening the door for leaks, structural damage and mold damage to your home.
Kearns Brothers can repair any and all chimney issues.
Without protection from water repellent, all new and existing masonry chimneys are susceptible to water damage, even after they are repaired. Kearns Brothers’ ChimneySaver water repellents come with a 10 year warranty and have been the first choice of chimney professionals for nearly 20 years. The repellent reduces water penetration into the masonry by 99.9% according to ASTM tests conducted at the University of Wyoming. ChimneySaver is 100% vapor permeable, which means it won’t trap water vapors.
A chimney crown is a masonry roof that covers the top of your chimney. It is designed to prevent water from seeping into the masonry below. Water-damaged or cracked chimney crowns can lead to costly chimney repairs. Chimneys are often capped improperly with mortar crowns instead of the recommended cast-in-place concrete crowns. Kearns Brothers’ flex crown solution is an elastomeric coating that forms a flexible waterproof membrane to protect chimney crowns. It dries in about 6 hours and cures in about 24 hours to a natural concrete/mortar appearance and comes with a 10 year manufacturer’s warranty.
Chimney leaks are a common problem due to improper flashing design and construction. It takes a skilled craftsman to install a flashing that will
perform maintenance free for many years. A common construction “shortcut” is referred to as “pinning” the flashing. This is when the metal flashing is nailed or “pinned” to the mortar, and caulking applied along the top portion of the flashing to waterproof the system. This method is prone to popping loose and developing cracks in the caulking after only a few years of UV exposure. If pinned, chimneys will require constant maintenance to remain watertight.
Kearns Brothers’ craftsmen deliver the utmost attention to detail. Using the “Grind and Tuck” technique, Kearns Brothers grinds the mortar joints, bending the metal along the top of the flashing and tucking it back into the mortar joints. Then mortar caulk is pointed back into the joint causing a permanent watertight seal.
Tuckpointing is a repair that focuses on the mortar joint between brick or stone and does not address the masonry chimney unit itself. There are many situations where tuckpointing is almost a complete waste of money. If you are considering a repair that involves tuckpointing, get a free evaluation from Kearns Brothers.
