Vetting a Markham contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Markham 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 waterproofing).
Common questions
Is waterproofing covered by home insurance in Markham?
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.
What warranty do you offer on waterproofing in Markham?
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.
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 Markham?
Cleaning and inspection are permit-exempt in Markham. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
How long does waterproofing take in Markham?
2–3 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
How much does waterproofing cost in Markham?
Most Markham jobs land between $387 and $619. Complex access or heritage masonry can reach $1,006. We quote fixed price after a free on-site scope.
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.
Do you service condos and heritage homes in Markham?
Yes. Condo boards in Markham typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
