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).
Vetting a Markham contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Markham references from the last 12 months you can call — not read.
Common questions
How much does damper repair cost in Markham?
Most Markham jobs land between $221 and $353. Complex access or heritage masonry can reach $573. We quote fixed price after a free on-site scope.
What warranty do you offer on damper repair in Markham?
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 damper repair covered by home insurance in Markham?
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.
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 damper repair in Markham?
Late September through mid-November with Markham averaging 148cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
Do you service condos and heritage homes in Markham?
Yes. Condo boards in Markham typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
Do you offer same-day damper repair in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
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.
