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 waterproofing).
Vetting a Mississauga contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Mississauga references from the last 12 months you can call — not read.
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.
Do you offer same-day waterproofing in Mississauga?
Usually — call before 9am and we'll confirm a same-day arrival window inside Mississauga for most standard scopes.
Is waterproofing covered by home insurance in Mississauga?
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 service condos and heritage homes in Mississauga?
Yes. Condo boards in Mississauga typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
Do you need a permit for waterproofing in Mississauga?
Cleaning and inspection are permit-exempt in Mississauga. 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 waterproofing in Mississauga?
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.
When's the best time of year for waterproofing in Mississauga?
Late September through mid-November with Mississauga averaging 95cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
How long does waterproofing take in Mississauga?
2–3 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
