Common questions
Do you offer same-day damper repair in Ajax?
Usually — call before 9am and we'll confirm a same-day arrival window inside Ajax for most standard scopes.
What warranty do you offer on damper repair in Ajax?
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 need a permit for damper repair in Ajax?
Cleaning and inspection are permit-exempt in Ajax. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
When's the best time of year for damper repair in Ajax?
Late September through mid-November with Ajax averaging 95cm 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.
Is damper repair covered by home insurance in Ajax?
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.
