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 Cambridge contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Cambridge 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.
Common questions
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 Cambridge?
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 need a permit for moss treatment in Cambridge?
Cleaning and inspection are permit-exempt in Cambridge. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
Is moss treatment covered by home insurance in Cambridge?
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 Cambridge?
Usually — call before 9am and we'll confirm a same-day arrival window inside Cambridge for most standard scopes.
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.
When's the best time of year for moss treatment in Cambridge?
Late September through mid-November with Cambridge averaging 109cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
Do you service condos and heritage homes in Cambridge?
Yes. Condo boards in Cambridge typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
