Chimney Waterproofing Done in the Right Order
Repairs first, then a breathable repellent, backed by our workmanship warranty.
Water repellents and waterproof coatings are different products
The National Park Service draws a clear line between the two. A water repellent keeps liquid water out while letting water vapor pass through the masonry. A waterproof coating seals the surface against both, and that group includes bituminous coatings and some elastomeric paints.
On a chimney, sealing in vapor is a problem, because any moisture that does get into the brick has nowhere to go. That is why our specialists use breathable repellents on chimney faces. When a product is sold simply as a sealer, we read its label before it goes anywhere near your home.
A test patch before the whole chimney
Brick varies, and so does the way it takes a repellent. The Brick Industry Association recommends trying the product on a test area of at least 10 square feet, and repellent labels ask for a small test before general application.
Our pros pick a spot that represents the chimney, treat it and let it dry fully before you look at it with us. If the color or texture changes in a way you do not like, we talk through another product before the rest of your chimney in Keystone is touched.
Rain straight down the flue is a cap problem
Water dripping into the firebox during a storm often falls straight down an uncovered flue. No treatment on the outside of the chimney will stop rain that enters from the top.
Our pros look at the chimney cap before recommending waterproofing. If the cap is missing, rusted through or the wrong size, replacing it is usually the first and most useful fix, and it is priced separately so you can see where your money goes.
Stone, block and stucco chimneys
Most published waterproofing guidance, including the Brick Industry Association note we work from, is written for clay brick. Natural stone and stucco over block take water differently and can react differently to a product.
Our specialists identify the material on your chimney and use a repellent whose label names that surface, with a test area first. If a stucco chimney has cracks or hollow spots, those are repaired before any treatment, and the estimate shows each step.
