Before you hire in Kanata

Do you need a permit for basement waterproofing in Kanata?

In Ottawa damp proofing an existing basement does not require a building permit.

Underpinning, lowering a floor or altering structure does. Exempt from a building permit still means the work must comply with the Ontario Building Code and any applicable law, such as the Zoning By-law.

Designated heritage buildings and properties inside a Heritage District Overlay are not covered by these exemptions, and the City asks owners to confirm with a Building Client Service Centre before starting.

Hiring in Kanata

Choosing a waterproofing company in Kanata

Kanata is Ottawa's west-end tech hub, a mix of established 1990s and 2000s subdivisions in Kanata Lakes, Bridlewood, and Katimavik plus newer builds further west. Because much of the housing stock is now 20 to 30 years old, the most common projects here are first roof replacements, deck rebuilds, window and door upgrades, and basement finishing. The service businesses below serve Kanata and the wider west end.

  • Diagnosis before sealing

    Sealing a wall without finding the source often just moves the leak. A good contractor traces whether it is grading, weeping tile, or a crack before quoting a fix.

  • Interior vs exterior waterproofing

    Interior systems manage water that gets in; exterior excavation stops it at the wall. They solve different problems at very different costs. Ask which your situation actually needs.
