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

What warranty do you offer on cap replacement in Oakville?

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 cap replacement covered by home insurance in Oakville?

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.

Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
