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).
Vetting a Caledon contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Caledon references from the last 12 months you can call — not read.
Common questions
How long does moss treatment take in Caledon?
3–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
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.
Is moss treatment covered by home insurance in Caledon?
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.
How much does moss treatment cost in Caledon?
Most Caledon jobs land between $335 and $536. Complex access or heritage masonry can reach $871. We quote fixed price after a free on-site scope.
Do you service condos and heritage homes in Caledon?
Yes. Condo boards in Caledon typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
When's the best time of year for moss treatment in Caledon?
Late September through mid-November with Caledon averaging 144cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.

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.
