Vetting a Toronto contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Toronto references from the last 12 months you can call — not read.
Red flags on quotes
Verbal-only pricing, deposits above 20%, cash-only discounts, and unwillingness to itemise materials by brand are the top four. Any one is a pass.
What a defensible quote looks like
Written scope with photos, itemised labour + materials, 30-day validity, WSIB and liability certificate attached, and named workmanship warranty (5 years is the current bar for ice dam prevention).
Common questions
Do you offer same-day ice dam prevention in Toronto?
Usually — call before 9am and we'll confirm a same-day arrival window inside Toronto for most standard scopes.
What warranty do you offer on ice dam prevention in Toronto?
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.
Is ice dam prevention covered by home insurance in Toronto?
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 Toronto?
3–5 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.
When's the best time of year for ice dam prevention in Toronto?
Late September through mid-November with Toronto averaging 127cm 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.
How much does ice dam prevention cost in Toronto?
Most Toronto jobs land between $325 and $519. Complex access or heritage masonry can reach $844. We quote fixed price after a free on-site scope.
