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 vent repair / reroute).
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.
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
Do you need a permit for vent repair / reroute in Markham?
Cleaning and inspection are permit-exempt in Markham. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
What warranty do you offer on vent repair / reroute 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 vent repair / reroute 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.
When's the best time of year for vent repair / reroute 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.
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 vent repair / reroute cost in Markham?
Most Markham 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 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 vent repair / reroute in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
