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 Ajax contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Ajax references from the last 12 months you can call — not read.
Common questions
How much does moss treatment cost in Ajax?
Most Ajax jobs land between $387 and $620. Complex access or heritage masonry can reach $1,007. We quote fixed price after a free on-site scope.
When's the best time of year for moss treatment in Ajax?
Late September through mid-November with Ajax averaging 95cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
Do you need a permit for moss treatment in Ajax?
Cleaning and inspection are permit-exempt in Ajax. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
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 Ajax?
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.
Do you offer same-day moss treatment in Ajax?
Usually — call before 9am and we'll confirm a same-day arrival window inside Ajax for most standard scopes.
What warranty do you offer on moss treatment in Ajax?
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.
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.
