Chimney Waterproofing
Cracks and erosion in your chimney brick let rainwater seep straight down into the attic and firebox. We seal the brick permanently — so the next storm stays outside where it belongs.

If water's already getting in, here's how you'll know.
Even hairline cracks are enough. Once moisture enters the masonry, it expands with every freeze — making next season’s damage worse than this one’s.
Water stains on the ceiling or wall near the chimney
Rain leaking into the attic during storms
Damp, musty odors from the fireplace
Visible cracking, flaking, or erosion in brick or mortar
Water pooling or dripping in the firebox after rain
A chimney that's never been waterproofed or capped
One sprayed coat. A permanent barrier.
We spray a specialized sealant directly onto the exterior chimney brick, forming a permanent, breathable barrier. The treatment lets existing moisture and vapor escape from inside the masonry, while blocking new rain from soaking back in.
Because it’s applied straight to the brick face, the same treatment works on virtually any masonry surface — not just chimneys.
The same coat protects your whole house.
The sealant works on all brick — not only chimney masonry. We offer whole-house waterproofing, so every exposed brick surface gets the same long-term protection.
Spray, whole house
Backed twice over — by the manufacturer and by us.
Year Manufacturer Warranty
Coverage on the sealant itself, direct from the product manufacturer.
Year Chimney Sweep Guarantee
Our own workmanship warranty, on top of the manufacturer's coverage.
Waterproofing works best as part of a full water-protection plan.
Flashing Repair
Seals the junction between chimney and roofline — a common leak point that waterproofing alone doesn't cover.
Chimney Cap Installation
Closes off the top of the flue for chimneys that don't already have one, keeping rain out from above.
Don't wait for a crack to become a leak.
Call The Chimney Sweep today and we’ll get your chimney — and if you want, your whole house — sealed against Texas weather for good.
