What needs a pro

Anything requiring roof access, working chemicals or sealants, disturbing masonry, disassembling the appliance, or interpreting a scan. The insurance and liability exposure on DIY cap install is disproportionate to the cost savings.

The Oshawa rental market angle

Landlord cap install DIY on rental units in Oshawa voids most policies and shifts full liability to the owner under RTA §20. Not worth it.

What you can safely DIY

Visual inspection with a flashlight, exterior debris clearing from the cap area (from a stable ladder, not the roof), and photo-documentation of concerns. That's the safe list.

Common questions

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.

How long does cap install take in Oshawa?

60 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 cap install 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.

When's the best time of year for cap install 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.

Is cap install 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 offer same-day cap install in Oshawa?

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

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.

What warranty do you offer on cap install in Oshawa?

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.
