Common questions

Is flashing 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.

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.

When's the best time of year for flashing 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.

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.

How long does flashing repair take in Ajax?

1–3 hrs 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 flashing 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 flashing 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.

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.
