Chimney Flashing Repair in Whitby
Professional chimney flashing repair in Whitby — 24 hour response, licensed & insured.
Where your chimney meets the roof in Whitby is the single most leak-prone spot on your entire home. Proper chimney flashing has two layers — step flashing woven into the shingles and counter-flashing tucked into the brick mortar joints. When either fails, water tracks straight into the wall.
Why chimney flashing repair matters in Whitby
Two-Layer System
Real chimney flashing is a two-part system. Anyone offering to 'just caulk it' is selling you a 12-month fix.
Mortar Cut Matters
Counter-flashing must be cut into the mortar joints — not surface-mounted. Surface-mount flashing on a chimney lasts one winter.
Ice And Water Shield
A proper chimney rework includes ice-and-water membrane under the flashing for a redundant seal.

Chimney Flashing Repair reviews in Whitby
Quoted over the phone, confirmed on site before starting, and the final invoice matched exactly. Refreshing in this trade.
Needed dated documentation for renewal. The report had the technician certification number and photos, and my insurer accepted it without a follow-up question.
1920s brick, plenty of quirks. The technician clearly knew older builds and pointed out mortar joints to watch rather than pushing a rebuild.
Had to move my appointment once, but the sweep itself was excellent and the crown sealing has held through the winter with no water staining.
FAQ
Almost always because it was surface-mounted and caulked instead of cut into the mortar.
Yes — that's the only way to do this repair properly. It's called a reglet cut.
Most chimney re-flashing jobs are a same-day, one-crew job.
