Common questions

How long does cap replacement take in Oshawa?

1–2 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.

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.

Is cap replacement covered by home insurance in Oshawa?

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.

Do you service condos and heritage homes in Oshawa?

Yes. Condo boards in Oshawa typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.

Do you offer same-day cap replacement in Oshawa?

Usually — call before 9am and we'll confirm a same-day arrival window inside Oshawa for most standard scopes.

When's the best time of year for cap replacement in Oshawa?

Late September through mid-November with Oshawa averaging 99cm 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 need a permit for cap replacement in Oshawa?

Cleaning and inspection are permit-exempt in Oshawa. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
