Vetting a Oakville contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Oakville 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 downspout extensions).
Common questions
