View The Foundation Guys Inc.Before you hire in Orléans
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.

Common questions
Hiring in Orléans
Orléans is Ottawa's large east-end community and a hub for the city's francophone population. It blends mature neighbourhoods like Convent Glen and Chapel Hill with newer developments toward Avalon and Cardinal Creek. The established east-end homes are prime candidates for roofing, eavestrough, window, and driveway work, while newer areas need decks, fences, and landscaping. Many businesses below serve Orléans bilingually.
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 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.
