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 Grimsby contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Grimsby references from the last 12 months you can call — not read.
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.
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 Grimsby?
Most Grimsby jobs land between $342 and $547. Complex access or heritage masonry can reach $889. We quote fixed price after a free on-site scope.
Do you service condos and heritage homes in Grimsby?
Yes. Condo boards in Grimsby typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
Do you offer same-day ice dam prevention in Grimsby?
Usually — call before 9am and we'll confirm a same-day arrival window inside Grimsby for most standard scopes.
When's the best time of year for ice dam prevention in Grimsby?
Late September through mid-November with Grimsby averaging 119cm 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 Grimsby?
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 Grimsby?
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.
