The Whitby scheduling window
We aim to complete pre-winter downspout extensions on Whitby 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 downspout extensions in Whitby
Late September through mid-November is the sweet spot: Whitby averages 97cm 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 55 annual cycles. Summer: UV degradation on any exposed sealant. Fall: raccoon and squirrel nesting before the cold snap.
