Chimney Leak Repair

Brick and mortar are porous, and water is the root cause of most chimney damage — spalling, joint failure, rust and freeze-thaw cracking all start with water getting in. A breathable repellent dramatically slows that absorption, which is one of the most cost-effective ways to extend the life of the masonry.
We make sure the surface is clean and any needed repairs are done first.
We apply a breathable, vapor-permeable water repellent to full coverage.
We focus on the weather-facing and most exposed masonry.
The repellent cures to shed water while letting the wall breathe.
Waterproofing makes a lot of sense in our climate specifically because of freeze-thaw. Every bit of water you keep out of the brick is water that can't freeze, expand and spall the face off. It's especially worthwhile right after masonry repairs, to protect the work you've just paid for.
Sealing it with the wrong product is. A film-forming sealer or paint traps moisture inside and makes spalling worse. A breathable repellent is different — it blocks liquid water from entering while letting vapor out, which is exactly what masonry needs.
A quality breathable repellent typically protects for several years before it's worth reapplying. We can check it during your annual inspection.
