How we prioritise
Active leaks, gas smell, and animal-in-flue jump the queue over cosmetic liner install work. We text realistic ETAs, not "we'll get to it."
Response windows across Markham
Standard bookings inside Markham: 3–5 business days. Same-day: usually before 2pm if we get the call by 9am. Emergency (water in flue, active leak): 90 minutes on weekdays, 3 hours weekends.
Weekend and holiday coverage
Saturday standard. Sunday and stat holidays are emergency-only with a documented callout fee that's waived if we book the follow-up job.
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.
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 liner install 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.
Do you need a permit for liner install 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.
Do you offer same-day liner install in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
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.
When's the best time of year for liner install 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 warranty do you offer on liner install 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.
