The Toronto scheduling window
We aim to complete pre-winter moss treatment on Toronto 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 moss treatment in Toronto
Late September through mid-November is the sweet spot: Toronto averages 127cm 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 70 annual cycles. Summer: UV degradation on any exposed sealant. Fall: raccoon and squirrel nesting before the cold snap.
Common questions
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 moss treatment in Toronto?
Usually — call before 9am and we'll confirm a same-day arrival window inside Toronto for most standard scopes.
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 moss treatment in Toronto?
Cleaning and inspection are permit-exempt in Toronto. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
Do you service condos and heritage homes in Toronto?
Yes. Condo boards in Toronto typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
How much does moss treatment cost in Toronto?
Most Toronto jobs land between $325 and $519. Complex access or heritage masonry can reach $844. We quote fixed price after a free on-site scope.
How long does moss treatment take in Toronto?
3–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
When's the best time of year for moss treatment in Toronto?
Late September through mid-November with Toronto averaging 127cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
