The Markham scheduling window
We aim to complete pre-winter insert install on Markham homes by the last Saturday in October. Book by Labour Day for that window — after that we're scheduling against weather.
Best month to schedule insert install in Markham
Late September through mid-November is the sweet spot: Markham averages 148cm of snow starting in December, so roof access closes fast. Spring bookings (April–May) are second-best and often 10–15% cheaper.
What breaks in each season
Winter: ice loading on the cap and flashing. Spring: freeze-thaw cracking in the crown from 67 annual cycles. Summer: UV degradation on any exposed sealant. Fall: raccoon and squirrel nesting before the cold snap.
Common questions
Do you offer same-day insert install in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.

Most Markham jobs land between $1,264 and $2,023. Complex access or heritage masonry can reach $3,287. We quote fixed price after a free on-site scope.
Do you need a permit for insert 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.

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.

1 day is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
