Best month to schedule downspout 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.
The Markham scheduling window
We aim to complete pre-winter downspout install on Markham homes by the last Saturday in October. Book by Labour Day for that window — after that we're scheduling against weather.
Common questions
How long does downspout install take in Markham?
45–90 min is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
What warranty do you offer on downspout 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.
Is downspout 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.
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.
Do you need a permit for downspout 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.
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.
Do you offer same-day downspout install in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
When's the best time of year for downspout 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.
