Which rules apply

Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most damper repair work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.

Permit thresholds in Whitby

Certifications that carry weight

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.

Common questions

How long does damper repair take in Whitby?

60–90 min is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.

Do you service condos and heritage homes in Whitby?

Yes. Condo boards in Whitby typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.

Do you offer same-day damper repair in Whitby?

Usually — call before 9am and we'll confirm a same-day arrival window inside Whitby for most standard scopes.

What warranty do you offer on damper repair in Whitby?

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.

Is damper repair covered by home insurance in Whitby?

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.

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.

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.

Do you need a permit for damper repair in Whitby?

Cleaning and inspection are permit-exempt in Whitby. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
