What Ice Dam Prevention actually costs in Ajax

Common questions
Do you need a permit for ice dam prevention 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 ice dam prevention 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.
Do you offer same-day ice dam prevention in Ajax?
Usually — call before 9am and we'll confirm a same-day arrival window inside Ajax for most standard scopes.
Is ice dam prevention 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 long does ice dam prevention take in Ajax?
3–5 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
How much does ice dam prevention cost in Ajax?
Most Ajax jobs land between $387 and $620. Complex access or heritage masonry can reach $1,007. We quote fixed price after a free on-site scope.
