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 waterproofing).
Vetting a Oshawa contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Oshawa 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
Do you service condos and heritage homes in Oshawa?
Yes. Condo boards in Oshawa typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
How long does waterproofing take in Oshawa?
2–3 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
What warranty do you offer on waterproofing in Oshawa?
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.
Is waterproofing covered by home insurance in Oshawa?
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.
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.
Do you need a permit for waterproofing in Oshawa?
Cleaning and inspection are permit-exempt in Oshawa. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
How much does waterproofing cost in Oshawa?
Most Oshawa jobs land between $446 and $714. Complex access or heritage masonry can reach $1,161. We quote fixed price after a free on-site scope.
Do you offer same-day waterproofing in Oshawa?
Usually — call before 9am and we'll confirm a same-day arrival window inside Oshawa for most standard scopes.
