A family chimney company working in Harbordale

Sealing a chimney sounds simple, and our family team does apply water repellents in Harbordale, but only as the last step of a sound repair. We are locally owned. Waterproofing sits beside the crown, flashing, cap and masonry repairs we also provide, and those usually come first. Brick industry guidance on clear coatings for masonry draws a clear line.

A water repellent that lets the masonry breathe allows water vapour inside the brick to escape. A film-forming coating, such as paint or some sealers, can trap that moisture behind the surface, where it can damage the brick face. The guidance also notes that a repellent does not bridge cracks or open joints. Those have to be repaired before any treatment goes on, or water will simply enter where the repellent cannot reach.

That is why our assessment starts with the parts that let water in, not with the product. We check the crown, the cap, the flashing and the joints. Then we decide whether a repellent will help once they are sound. If the chimney has been painted or coated before, tell us, because an old film can change what a new treatment is able to do.

Mention where you see water: stains inside, damp brick outside or rust in the firebox. Tell us whether the problem follows heavy rain or appears on its own. The free inspection sets out the repairs and the treatment as separate items, and the written estimate costs you nothing. Pricing is upfront, with no hidden fees.

If the repellent, or any other listed item, is approved no later than 72 hours after the free inspection, 10% comes off its price. We protect the surroundings while we work and clean up afterwards. Our written record of the work goes into your hands when the job is done, and the workmanship warranty applies.
