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.
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 roof cleaning).
Common questions
Do you need a permit for roof cleaning 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 warranty do you offer on roof cleaning 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.
Do you service condos and heritage homes in Ajax?
Yes. Condo boards in Ajax typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
Do you offer same-day roof cleaning in Ajax?
Usually — call before 9am and we'll confirm a same-day arrival window inside Ajax 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.
How much does roof cleaning cost in Ajax?
Most Ajax jobs land between $332 and $531. Complex access or heritage masonry can reach $863. We quote fixed price after a free on-site scope.
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.
Is roof cleaning 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.
