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 Whitby contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Whitby 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.
Common questions
When's the best time of year for ice dam prevention 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.
How much does ice dam prevention cost in Whitby?
Most Whitby jobs land between $391 and $625. Complex access or heritage masonry can reach $1,016. We quote fixed price after a free on-site scope.
Do you offer same-day ice dam prevention 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 ice dam prevention 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.
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.
Is ice dam prevention covered by home insurance in Whitby?
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.
