Vetting a Oakville contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Oakville 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
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.
Do you service condos and heritage homes in Oakville?
Yes. Condo boards in Oakville typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
What warranty do you offer on ice dam prevention in Oakville?
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.
How long does ice dam prevention take in Oakville?
3–5 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
When's the best time of year for ice dam prevention in Oakville?
Late September through mid-November with Oakville averaging 119cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
How much does ice dam prevention cost in Oakville?
Most Oakville jobs land between $370 and $592. Complex access or heritage masonry can reach $962. We quote fixed price after a free on-site scope.
Do you need a permit for ice dam prevention in Oakville?
Cleaning and inspection are permit-exempt in Oakville. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
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.
