Chimney Waterproofing & Crown Sealing in Oakville
Brick is a sponge. Every Ontario freeze-thaw cycle expands the water inside it until the face pops off. A vapour-permeable sealer keeps rain out while letting the chimney breathe — and costs a fraction of a rebuild.
What's included
Every chimney waterproofing & crown sealing includes
- Crown crack repair and flexible crown coating
- 100% vapour-permeable siloxane masonry sealer
- Hairline mortar joint repair before sealing
- Efflorescence cleaning and brick prep
- Cap and damper water-entry check
- 10-year sealer manufacturer warranty
How the visit works
- 1
Inspect and clean
We wash off efflorescence and moss so the sealer bonds to bare masonry.
- 2
Repair the crown
Cracks are filled and a flexible crown coat is troweled over the full slab with a proper drip edge.
- 3
Flood-coat the brick
Sealer is applied to saturation, top down, on every exposed face — not misted on.
- 4
Verify and warranty
Beading test after cure, photo report, and the manufacturer warranty registered in your name.
Signs you need this service
- White chalky staining (efflorescence) on the brick
- Brick faces flaking, popping or crumbling (spalling)
- Hairline or wide cracks across the concrete crown
- Damp patches on the chimney breast inside the house
- The chimney was rebuilt or repointed and was never sealed
