Red flags on quotes
Verbal-only pricing, deposits above 20%, cash-only discounts, and unwillingness to itemise materials by brand are the top four. Any one is a pass.
What a defensible quote looks like
Written scope with photos, itemised labour + materials, 30-day validity, WSIB and liability certificate attached, and named workmanship warranty (5 years is the current bar for downspout extensions).
Vetting a Whitby contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Whitby references from the last 12 months you can call — not read.
Common questions
Do you need a permit for downspout extensions in Whitby?
Cleaning and inspection are permit-exempt in Whitby. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
How long does downspout extensions take in Whitby?
30–60 min is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
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 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.
What warranty do you offer on downspout extensions in Whitby?
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 extensions covered by home insurance in Whitby?
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 downspout extensions in Whitby?
Late September through mid-November with Whitby averaging 97cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
Do you service condos and heritage homes in Whitby?
Yes. Condo boards in Whitby typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
