Storm Damage Guide: Chimney Relining After Severe Weather in Markham
This is the working reference we hand to Markham clients before we book a chimney relining appointment. Deeper freeze depths mean liner condensation and cap ice-loading. Below: what to expect, real numbers, and the questions worth asking before you book.
Quick answer
The three signs Markham homeowners keep missing on chimney relining: smell changes, staining above the firebox, and unusual sound. Any one means schedule; two together means stop-use.
Typical
$1,656–$2,650
Duration
1 day
Freeze-thaw
67/yr
When to stop using the appliance
Any active water ingress, visible flame licking outside the firebox opening, or the smell of gas products in the room means shut down and call. Insurance coverage on damage during "known unsafe operation" is thin.
Signs the chimney relining can't wait
The most reliable early warnings on Markham homes: smell changes near the appliance, staining above the firebox or on interior ceilings, unusual soot at the cap, and any water inside the smoke chamber. Any one of these is a call — two together is a stop-use.
The 90-second self-check
Look at the cap for gap or crushing, walk the crown for hairline cracks (67 freeze-thaw days a year here will find any weakness), and shine a light up the flue for glazing. Photograph anything unclear and text it over.
Common questions
Is chimney relining 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 chimney relining 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.
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.
What warranty do you offer on chimney relining 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.
Do you need a permit for chimney relining 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 chimney relining in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
How long does chimney relining take in Markham?
1 day is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
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.
