WETT SITE-Comprehensive, CSIA CCP or CCS, and WSIB clearance are the three signals adjusters and buyers accept without pushback. HRAI membership adds credibility on venting work.
Which rules apply
Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most flashing repair work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.

Common questions
Are you WETT and WSIB certified?
Yes — WETT SITE-Comprehensive #C-46082, CSIA #12408, and active WSIB #7248194. Certificates emailed on request before the job.
How much does flashing repair cost in Markham?
Most Markham jobs land between $293 and $469. Complex access or heritage masonry can reach $762. We quote fixed price after a free on-site scope.
When's the best time of year for flashing repair in Markham?
Late September through mid-November with Markham averaging 148cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
What if it rains or snows on the booking day?
Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
What warranty do you offer on flashing repair in Markham?
Five-year written workmanship warranty on materials and labour, transferable to a new homeowner within that window. Manufacturer warranties on any installed products pass through separately.
Do you offer same-day flashing repair in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
Do you need a permit for flashing repair in Markham?
Cleaning and inspection are permit-exempt in Markham. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
Is flashing repair covered by home insurance in Markham?
Sudden damage (storm, animal, appliance failure) is usually covered minus deductible. Gradual wear generally isn't. A written pro assessment before the claim call materially improves outcomes.
