Vetting a Mississauga contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Mississauga 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 damper repair).
Common questions
What warranty do you offer on damper repair in Mississauga?
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.
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 need a permit for damper repair in Mississauga?
Cleaning and inspection are permit-exempt in Mississauga. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
How much does damper repair cost in Mississauga?
Most Mississauga jobs land between $212 and $338. Complex access or heritage masonry can reach $550. We quote fixed price after a free on-site scope.
Do you offer same-day damper repair in Mississauga?
Usually — call before 9am and we'll confirm a same-day arrival window inside Mississauga for most standard scopes.
When's the best time of year for damper repair in Mississauga?
Late September through mid-November with Mississauga averaging 95cm 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.
Is damper repair covered by home insurance in Mississauga?
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.
