What does concrete repair and leveling run per square foot in Toronto?
According to DryShield Basement Waterproofing (Toronto/GTA, updated July 2026), foundation crack injection - polyurethane (leak-stopping) runs $750–$1,000 per crack in the GTA, while foundation crack injection - epoxy (structural bonding) runs $750–$1,500 per crack (DryShield Basement Waterproofing (Toronto/GTA, updated July 2026)). Add 13% HST to any quote. The table below breaks down 8 line items, each with its own named source.
| Item | Typical range | Unit | Source |
|---|---|---|---|
| Foundation crack injection - polyurethane (leak-stopping)DryShield's own polyurethane tier, best for stopping active leaks with a flexible seal that tolerates seasonal movement. HST and finishing work such as drywall removal, insulation and repainting are not included unless quoted, and final pricing is confirmed after inspection. | $750–$1,000 | per crack | DryShield Basement Waterproofing (Toronto/GTA, updated July 2026) |
| Foundation crack injection - epoxy (structural bonding)DryShield's own epoxy tier, for bonding structural cracks in poured concrete where strength restoration is the goal. Same floor as polyurethane, higher ceiling. Tie-rod hole sealing is separate at $75 to $150 per hole; volume discounts apply from three cracks up. | $750–$1,500 | per crack | DryShield Basement Waterproofing (Toronto/GTA, updated July 2026) |
| Exterior excavation + membrane crack repairExterior repair means excavating to the footing and installing a waterproofing membrane, so it is priced per crack but scoped as a dig. RenoQuotes repeats the same $3,000 to $5,500 as its average further down the page. | $3,000–$5,500 | per crack | RenoQuotes (Canada, 2026) |
| Minor surface crack sealing (porch/walkway/slab)One day of work in Toronto Concrete Repairs' Average Costs table. The same page's FAQ text says minor crack sealing starts at $300 to $600, so confirm scope before treating $600 as the floor. | $600–$900 | per job | Toronto Concrete Repairs |
| Parging - standard applicationGTA Brickworks says the range is wide because scope, surface condition and what is found once the old coating comes off vary a lot. It works out to $900 to $3,500 for a standard detached home's foundation. | $3–$8 | per sq ft | GTA Masonry (May 2026) |
| Parging - premium two-coat installed (incl. prep + bonding agent)Alasya's rate is for a two-coat application installed, which is why it sits above GTA Brickworks' $3 to $8 standard-application figure. | $6–$12 | per sq ft | Alasya Construction (Toronto, 2026) |
| Parging patch repair (under 10 sq ft)Under 10 sq ft only. GTA Brickworks prices anything larger by the square foot at $3 to $8. | $250–$600 | per job | GTA Masonry (May 2026) |
| Full foundation re-parge (detached Toronto home)A 2026 figure for a typical Toronto detached home. Alasya says homes with larger exposed perimeters, significant existing damage, or an acrylic finish coat land at the higher end. | $3,500–$7,000 | per home | Alasya Construction (Toronto, 2026) |
How does ConcreteFinder rank concrete repair contractors?
ConcreteFinder scores every company out of 100. Reviews are 45 of that, weighing review volume alongside the star rating so consistent, high-volume reputations rise to the top. The remaining 47 count what a company states on its own website, each line quoted from the page it was read off, and the details on the record: a website that answers, photographs, a phone, posted hours. Never paid placement.
GTA-wide, 74% of the rated concrete repair contractors already sit at 4.8★ or better, so read a two-place gap on this list as a real one. Placement cannot be bought. Read how the order is calculated.

Questions to ask your contractor
- Is my slab a candidate for lifting, or does it need replacing? Repair versus replace costs
- For lifting, do you use mudjacking or polyurethane foam, and why?
- How do you treat the cracks so they do not reopen?
- Is this cosmetic spalling or a structural problem I should have assessed?
- What warranty covers the repair or the re-level?
Frequently asked questions
What is the going rate for concrete repair and leveling across Toronto and the GTA?
According to DryShield Basement Waterproofing (Toronto/GTA, updated July 2026), foundation crack injection - polyurethane (leak-stopping) runs $750–$1,000 per crack, and foundation crack injection - epoxy (structural bonding) runs $750–$1,500 per crack (DryShield Basement Waterproofing (Toronto/GTA, updated July 2026)). Quotes are pre-tax, so add 13% HST on top. The concrete repair & leveling cost guide here breaks the job into line items and names the source behind each one.
How do I tell a solid GTA concrete repair contractor from a cheap pour?
Compare at least three written, itemized quotes rather than defaulting to the cheapest. ConcreteFinder ranks 83 concrete repair contractors at an average 4.82★ Google rating; the middle of that field sits on 27 reviews. Start with the shortlist above, then ask each crew for the address of a pour it finished at least two winters ago and go and look at the joints.
Which months are the right ones to schedule concrete repair and leveling in Toronto?
The GTA concrete repair and leveling season runs Apr–Nov, because fresh concrete needs above-freezing temperatures to cure. Reputable companies book several weeks ahead in peak months, so request quotes early; shoulder-season pours in spring or fall often win better pricing.
Do I need a permit, and is HST included in concrete repair and leveling quotes?
Add 13% HST to any quote, since concrete work is taxable in Ontario and most posted prices exclude it. Permit needs depend on scope: a like-for-like driveway or slab repour rarely needs one, but widening a driveway, altering the curb cut or boulevard, and any structural foundation or underpinning work require municipal approval and often an engineer, which a reputable contractor arranges. See ConcreteFinder's concrete repair & leveling cost guide for the Ontario rules.
Will a contractor move up this list by paying ConcreteFinder?
No, and there is no product to buy that would change it. The order is a Google rating pulled toward the field average by review count, plus small boosts for a website, a phone number and photographs on file. Money is not one of the inputs. GTA-wide, 74% of the rated concrete repair contractors already sit at 4.8★ or better. In a field that tight, a couple of positions is a real difference, not noise.
