When to Call for Chimney Leak Repair
Active Interior Stains
Brown water rings around the chimney, peeling paint, or attic dampness near the stack.
After Heavy Wind/Rain
Wind‑driven rain exposes loose step flashing and open counter‑flashings against brick.
Freeze–Thaw Damage
Cracked crowns and mortar joints allow water entry that worsens every winter.
Chimney Leak Repair Toronto — Common Causes
Most leaks begin at detailing—not the shingles. Our inspection focuses on the chimney stack, the roof junction, and nearby walls to pinpoint the failure before we repair.
- Loose or short step flashing
- Open counter‑flashing cut too shallow
- Cracked crown/cap or missing drip edges
- Deteriorated mortar joints and brick faces
- No cricket/saddle on the uphill side
Our Chimney Leak Repair Process
- Inspect & Diagnose. Photo review of flashing, brick, crown and roof junction; moisture check in attic where accessible.
- Scope & Quote. We outline the fix—re‑flash, re‑caulk, crown patch, mortar tuck‑point, cricket install—plus timelines.
- Repair. Clean removal of failed sealants/metal, proper step flashing and counter‑flashing, crown/cap repair, new kick‑out as needed.
- Test & Photos. Water test if required and a labelled photo set for your records.
Pricing & Scheduling
Simple reseals start at a modest service fee; full re‑flash or crown rebuilds are quoted after inspection. Multi‑storey access or steep slopes may require additional safety setup.
Our crews carry active WSIB Clearance coverage and we follow BBB Profile when masonry or structural work is involved.
- Weekday appointments with limited same‑day tarping
- Weather‑aware scheduling; we work safely around rain
- Photo report included with every job
What Affects Price
- Chimney size, height & roof pitch
- Brick/mortar condition and crown damage
- Access (ladders, scaffolding) and crickets/flashing complexity
When you book, we confirm access, chimney height, and any interior staining so the crew arrives prepared. On site, we start with photos and moisture readings, then isolate the failure point at flashing, crown, or brick. You’ll get a clear scope with materials and steps (re‑flash, counter‑flashing cut and seal, crown patch, tuck‑pointing, or cricket install) so you know exactly what’s being done and why. If rain is forecast, we can tarp or temporarily seal to stop active leaks until the permanent fix. All work is documented with after‑photos, and we keep the site clean—no metal offcuts or debris left behind. Straight pricing, reliable timing, and a workmanship warranty keep your chimney dry for the long term.
Chimney Repairs Are Residential Roofing Work
Most chimney leaks start where the roof meets the brick, so they’re best handled by a residential roofing crew. The fix is rarely “just masonry.” We check and correct step flashing, counter‑flashing cuts, kick‑outs, sealants, and the chimney crown so water can’t track behind the metal or into the wall. On Chimney Leak Repair Toronto jobs, our techs work from the roof with proper access and safety, then coordinate tuck‑pointing or crown patching as needed. This approach stops the leak at its source and protects shingles, sheathing and interior finishes. If a cricket or saddle is missing on the uphill side, we’ll recommend one to keep water from pooling in the first place.
