Find a Waterproofing Contractor in Ottawa

Tell us where the water is getting in and we will send your request to local Ottawa waterproofing contractors, who reply to you by email.

Fields marked * are required. No phone number needed — your matches reply by email. Your request is shared only with the contractors we send it to.

How It Works

  • Tell us what you need: exterior or interior waterproofing, drain tile, a crack, a sump pump, a backwater valve, a window well or a foundation repair
  • We send your request on to local waterproofing contractors in the Ottawa Construction Network directory
  • They reply to you by email to arrange a look at the house and a written quote
  • Compare quotes, ask questions and decide if it is the right fit, with no obligation

What to Check Before You Hire

  • A written quote that names the walls and length, dampproofing or waterproofing, whether the drain tile is replaced and where it drains, and any pit, pump or valve
  • Who pulls the City permit where the job needs one, and who requests the locate before any digging (free, and required by law)
  • Who does the plumbing part of a sump or backwater valve job: plumber is a compulsory trade in Ontario
  • A written contract with the scope, price and dates; on a direct agreement, such as one signed at home, your 10-day cancellation right under the Consumer Protection Act, 2002
  • The warranty terms in writing: what is covered, for how long, and whether they transfer to a buyer
  • We do not screen or verify contractors, so check these yourself before you sign

The City's Protective Plumbing Rebate The City rebates some backwater valve and sump pump work after a permit and inspection. It covers devices, not membranes or crack repairs, and the City lists the program as currently under review: check ottawa.ca before you rely on it.
