Real per-crack pricing, what drives it up or down, and a calculator that gives you a planning estimate in seconds.
In Toronto and the GTA, professional crack injection typically costs $750–$1,500 per crack at our current published rates — polyurethane leak-sealing runs $750–$1,000, structural epoxy $850–$1,500, and tie-rod hole sealing $75–$150 per hole, depending on crack length and access. Every repair includes a written quote before work starts and a transferable lifetime warranty. Price depends on what you are actually dealing with. Our guide to the five types of foundation crack walks through each pattern, and explains why crack width alone tells you far less than most quotes imply.

| Repair scenario | Typical price range (CAD) | Notes |
|---|---|---|
| Single crack, polyurethane, unfinished basement | $750–$1,000 | Most common repair |
| Single crack, structural epoxy | $850–$1,500 | Material + application time premium |
| Additional cracks, same visit | Volume pricing (3+ cracks) | Quote typically below single-crack rates |
| Tie-rod hole sealing | $75–$150 per hole | Small round formwork leaks |
| Finished basement access | Quoted at assessment | Restoration quoted separately |
Prices current at our current published rates, aligned with our published Ontario pricing; typical pricing assumes an accessible poured-concrete crack up to ~6–8 ft. Confirmed in writing at your free assessment. HST extra.
Materials and injection time scale with the crack, floor to top; a 10-foot wall costs more than a 4-foot pony wall.
Polyurethane leak-sealing is the economical standard; structural epoxy costs more and cures slower.
An exposed wall is the base case. Finished basements need drywall opened — smallest section possible.
The first crack carries the visit cost; additional cracks on the same visit price lower.
Old failed patches must be drilled out; very wide cracks need staged fills; high water flow needs flow-control resins.
The season, whether the crack is actively leaking, or how urgently you book. No storm surcharges.
| Approach | Typical GTA cost | Stops the leak? | Notes |
|---|---|---|---|
| DIY kit | ~$60–$150 | Rarely, briefly | Face-fill only; complicates real repair later |
| Hydraulic cement / caulk patch | Under $100 in materials | Temporarily | Rigid patch on a moving wall — fails in seasons |
| Professional injection | $750–$1,500 per crack | Yes — full depth | One visit, warrantied, no digging |
| Exterior excavation + membrane | $5,000–$20,000+ | Yes | Right answer for some walls (block/stone) — overkill for a single poured-wall crack |
The City of Toronto Basement Flooding Protection Subsidy, and equivalent Peel and Halton programs, subsidize eligible flood-protection work for homeowners. Program rules, eligible items and amounts change — and not every crack repair qualifies — so we review current program fit at your assessment rather than promising a rebate on a webpage. As an eligible contractor for these programs, we’ll walk you through the current rules honestly, including when your repair doesn’t qualify.
Different materials (kit-grade vs. commercial resins), different depths of repair (face-fill vs. full-depth), different warranties, and different overheads. A low quote that patches the visible face costs more over five years than a full-depth injection done once. When you compare quotes, compare what’s included — the resin grade, the depth of fill, and the warranty behind it — not just the number at the bottom.
As long as it’s:
Different search words, same wall — with one important exception.
Homeowners search this a dozen ways — foundation crack repair cost, basement crack repair cost, crack injection price — and for a crack in a poured concrete wall they all land on the same published ranges above: polyurethane from $750, epoxy from $850, every additional crack 5% off. The word in front doesn’t change the repair. The exception worth knowing: if what you’re pricing is more than a crack — a bowing wall, stair-step movement across a block wall, or settlement — that’s a structural project, not an injection, and it’s priced after a foundation assessment rather than from this table. Not sure which side you’re on? Start with a basement crack repair assessment — it’s free either way.
