Keep the rain out, let the brick breathe.
Breathable water repellents, repointing, crown repair and flashing work that protect chimney brick from water, freeze damage and staining.
- Fixes first: Crown, cap, flashing and mortar repair
- Repellent: Breathable, vapor-permeable products
- Not used: Film-forming sealers that trap water
What it is, and why it matters.
Brick and mortar are porous. They soak up water from rain and from the air, and when that water freezes it can crack the brick from the inside. A chimney, which is exposed on all sides, is hit harder than most walls.
We protect chimneys in Nashville and across Middle Tennessee from the top down. The work starts by fixing the leaks, which means the crown, the cap, the flashing and the mortar joints, and then we apply a breathable repellent that keeps liquid water out while letting vapor escape.
Four things done right.
The leaks fixed first
A repellent cannot fix a cracked crown or a failed flashing, so we repair those first.
A product that breathes
A vapor-permeable repellent lets moisture out and keeps liquid water out.
No shiny coatings
We avoid film-forming sealers that can trap moisture and make brick spall.
Tested on a small spot
We check the product on a small area so you see the result first.

Chimney Waterproofing: common questions
Will waterproofing stop a chimney leak?
Only if the leak is coming through the brick. Most chimney leaks come through the crown, the cap or the flashing, and those need repair, not a coating.
Is a clear sealer safe for brick?
A breathable repellent is. A thick, shiny film-forming sealer can trap moisture behind it and damage the brick, so we avoid those.
