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.
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 moss treatment).
Common questions
Is moss treatment 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.
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.
Do you need a permit for moss treatment 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 much does moss treatment cost in Whitby?
Most Whitby jobs land between $391 and $625. Complex access or heritage masonry can reach $1,016. We quote fixed price after a free on-site scope.
How long does moss treatment take in Whitby?
3–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
Do you offer same-day moss treatment in Whitby?
Usually — call before 9am and we'll confirm a same-day arrival window inside Whitby for most standard scopes.
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.
