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.
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 wett inspection is disproportionate to the cost savings.
The Whitby rental market angle
Landlord wett inspection DIY on rental units in Whitby voids most policies and shifts full liability to the owner under RTA §20. Not worth it.
Common questions
How long does wett inspection take in Whitby?
60–90 min is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
What warranty do you offer on wett inspection in Whitby?
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 offer same-day wett inspection in Whitby?
Usually — call before 9am and we'll confirm a same-day arrival window inside Whitby for most standard scopes.
Do you need a permit for wett inspection in Whitby?
Cleaning and inspection are permit-exempt in Whitby. 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 wett inspection in Whitby?
Late September through mid-November with Whitby averaging 97cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
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.
Do you service condos and heritage homes in Whitby?
Yes. Condo boards in Whitby 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.
