Foundation repair, sealing & inspection in Ottawa

Interior polyurethane or epoxy injection for a single crack starts from $450. If water is tracking in from outside and the fix needs excavation, membrane and backfill, that's a bigger job — typically $2,000–$3,500 depending on depth and access. We diagnose which one your crack needs before quoting either.

Thin vertical hairline cracks are usually just shrinkage and low-risk. Horizontal cracks, diagonal or stair-step cracks, ones wider than a dime, or ones where the wall bulges or the crack keeps growing, are signs of real movement and worth a proper assessment — sometimes by a structural engineer, not just a contractor.

Often, yes — if the job actually includes excavation, membrane and backfill. A full exterior crack repair with those steps typically runs $2,000–$3,000 in Ottawa. A rock-bottom quote is worth a direct question: does the price include digging down to the footing, or just surface patching that fails again?

Often, yes. Interior injection — polyurethane or epoxy pumped directly into the crack from inside the basement — seals most active leaks without excavation, from $450. We only recommend exterior excavation when the crack is tied to a drainage or membrane failure that interior injection can't reach.

Yes — foundation repair and sealing is most of our work in Orleans, Kanata, Stittsville and Barrhaven. Interior injection starts from $450 per crack; jobs that need exterior excavation and a membrane typically run $2,000–$3,500. Each area has its own soil, from Orleans' Leda clay to Stittsville's till over bedrock, and we plan the repair around it.

We look at the full wall, inside and out: crack width, direction and movement, efflorescence and moisture marks, grading and downspouts, parging condition and weeping tile. You get a plain answer on whether the wall needs crack injection, exterior waterproofing, parging or a structural engineer, before any price is quoted.

Sealing closes a specific crack or joint, usually by interior injection. Waterproofing manages water on the whole wall: excavation, membrane, drainage board and weeping tile. If one crack is the only source, sealing is enough; if water is coming through several places or sitting against the wall, waterproofing is the honest fix.

If the crack is the only source and it's injected full wall-thickness, yes. But a wet basement after a thaw is sometimes one crack doing a lot of damage while the real cause is a clogged or failed weeping tile — we check drainage at the same time so you're not back here next spring.
