Vetting a Guelph contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Guelph 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
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.
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 warranty do you offer on moss treatment in Guelph?
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.
Do you service condos and heritage homes in Guelph?
Yes. Condo boards in Guelph typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
Is moss treatment covered by home insurance in Guelph?
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.
How long does moss treatment take in Guelph?
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 Guelph?
Usually — call before 9am and we'll confirm a same-day arrival window inside Guelph for most standard scopes.
How much does moss treatment cost in Guelph?
Most Guelph jobs land between $363 and $581. Complex access or heritage masonry can reach $944. We quote fixed price after a free on-site scope.
