Leak Repair you can actually trust
A stain on the ceiling beside the chimney has five likely sources, and only a staged hose test tells you which. We isolate the entry point — crown crack, missing cap, failed counter-flashing, porous brick, or a bad mortar joint — repair it, then re-test under water before we call it fixed.
Every Whitchurch-Stouffville job is quoted in writing before any work begins, and backed by a 5-year workmanship warranty.

Leak Repair in Whitchurch-Stouffville — common questions
Why is my chimney leaking only in heavy rain?+
Wind-driven rain gets through porous brick and hairline crown cracks that shed ordinary rainfall fine. That pattern usually points to the crown or the masonry face, not the flashing.
How much does chimney leak repair cost?+
Most GTA leak repairs land between $349 and $1,600 — flashing resealing at the low end, crown replacement plus waterproofing at the high end.
Can I just seal the chimney with waterproofing paint?+
No. Film-forming sealers trap moisture inside the brick, and the next freeze pops the face off. Only vapour-permeable siloxane repellents are safe on masonry.
