Where your chimney meets the roof in Windfields, Oshawa 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 Windfields, Oshawa

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.

Clean, quiet, respectful
Shoe covers, sheeting, and a sealed vacuum. My wife works from home and barely noticed they were here.

Explained the pricing upfront
Quoted over the phone, confirmed on site before starting, and the final invoice matched exactly. Refreshing in this trade.

Level 2 for a house sale
Recorded the whole flue on video for the buyer's agent. The chimney line item stopped being a negotiation point the same day.
Tom H. - Markham - 2026-04-03
Wood stove cleaning done right
Careful, knowledgeable, and explained the creosote grading so I actually understood why it mattered. Booking was easy and they arrived inside the window.

FAQ

Why did my flashing fail?

Almost always because it was surface-mounted and caulked instead of cut into the mortar.

Do you cut into the brick?

Yes — that's the only way to do this repair properly. It's called a reglet cut.

Timeline?

Most chimney re-flashing jobs are a same-day, one-crew job.
