The Ajax scheduling window
We aim to complete pre-winter damper repair on Ajax homes by the last Saturday in October. Book by Labour Day for that window — after that we're scheduling against weather.
Best month to schedule damper repair in Ajax
Late September through mid-November is the sweet spot: Ajax averages 95cm of snow starting in December, so roof access closes fast. Spring bookings (April–May) are second-best and often 10–15% cheaper.
Common questions
How long does damper repair take in Ajax?
60–90 min is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
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.
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 service condos and heritage homes in Ajax?
Yes. Condo boards in Ajax typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
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.
How much does damper repair cost in Ajax?
Most Ajax jobs land between $250 and $400. Complex access or heritage masonry can reach $649. We quote fixed price after a free on-site scope.
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.
