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).
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.
Common questions
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.
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 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.
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 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.
Do you need a permit for ice dam prevention in Toronto?
Cleaning and inspection are permit-exempt in Toronto. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
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.
Do you service condos and heritage homes in Toronto?
Yes. Condo boards in Toronto typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
