Before you hire
What should you check before hiring a waterproofing company in Ottawa?
The City of Ottawa runs a Residential Protective Plumbing Program offering rebates toward sump pumps and backwater valves, and it publishes the eligibility rules, the amounts and the deadline that applies. A homeowner hiring this trade can be owed money by the City without knowing it. Ottawa Service Directory is a listings site, not a regulator: we publish what a business reports about itself, so confirm what applies to your job with the source below and with The Foundation Guys Inc. before work starts.
