How Much Does Foundation Crack Injection Cost in Toronto in 2026?

WaterproofingIndex compiled this table from 12 named Canadian sources; where they disagreed, we widened the range rather than pick one.

Not every quote is the same job. These are the variables that move foundation crack injection pricing most in Toronto, so you can read a quote and see where the money goes.

• Injection material: polyurethane for stopping an active leak versus epoxy for bonding a structural crack, a difference DryShield prices at up to $500 per crack
• Crack length and depth of the wall, since a taller or thicker wall takes more ports and more resin
• Crack location and direction, with corners, horizontal cracks and awkward heights taking longer to set up and inject
• Wall access, which DryShield names alongside crack length, active leaking and a finished basement as the things that affect price
• Whether the crack is actively leaking at the time of the repair, which changes resin choice and the amount used
• Number of cracks on the same visit, since mobilisation is paid once and DryShield notes multi-crack packages carry volume discounts
• Whether reinforcement is added, since carbon fibre staples run $800 to $2,500 per crack on top of the injection (Ontario Foundations)
• Whether the real fault is outside the wall, because failed grading or drainage pushes the job to exterior excavation starting around $15,000 (Aquatech Waterproofing)
• Extras found during the same visit, such as tie-rod holes at $75 to $150 each (DryShield)

Ontario rules and Toronto's climate change the math in ways national price guides miss. Here is what applies locally, from HST to permits to freeze-thaw.

• HST: foundation repair and waterproofing work is taxable in Ontario, so add 13% HST to every quoted price above. A $900 injection lands at $1,017 once tax is added. Most contractor price pages publish pre-tax numbers.
• Warranty is a company promise, not a provincial rule. DryShield publishes a lifetime transferable warranty on eligible poured-concrete repairs and states it transfers to a new owner. Other GTA companies publish different terms, so ask for the warranty in writing and check what voids it.
• Interior crack injection is a repair inside an existing wall and is normally handled without a building permit. Anything that becomes underpinning, benching or structural alteration is a different job with different rules, so confirm scope with the contractor before signing.
• Municipal basement flooding subsidy programs exist in the GTA and contractors advertise eligibility for them. DryShield's page states it is an eligible contractor for City of Toronto, Peel and Halton basement flooding subsidies. Check the program rules directly with your municipality, since crack injection alone may not be a covered measure.
• Timing is seasonal in practice. Leaking foundation cracks in the GTA show up during heavy rain and spring melt, when outside water pressure around the foundation rises, so booking pressure is highest in spring.
• Get the invoice and the warranty paperwork. A cash job with no contract leaves you nothing to enforce if the crack leaks again, and a transferable warranty is only worth something if it is documented.

You can keep foundation crack injection costs down without cutting the parts that matter. These are the levers GTA homeowners actually use, each tied to a real number above.

• Get three written quotes. Published GTA prices for one crack run from $300 to $3,000 across real contractor pages, so the spread on your own crack will be large too.
• Bundle every crack into one visit. DryShield says a single injection takes about 1 to 2 hours and that several cracks can usually be sealed in one visit, with multi-crack packages carrying volume discounts.
• Fix the crack from inside before anyone talks about digging. Interior injection is a one-day job with no excavation (Gamcon), while exterior excavation for foundation repair typically starts at $15,000 (Aquatech Waterproofing).
• Ask whether polyurethane will do the job. If the crack is a non-structural leak rather than a moving structural crack, polyurethane is the cheaper material in both DryShield's and Ontario Foundations' published pricing.
• Clear access to the wall yourself. Wall access is one of the named price drivers on DryShield's page, so move storage, shelving and furniture away from the crack before the crew arrives.
• Add tie-rod holes to the same visit if you have them. At $75 to $150 per hole (DryShield) they are far cheaper handled during a booked injection than as a separate call-out.
• Consider a DIY kit only for a short, non-structural, hairline crack. Home Depot Canada listed a DRICORE crack injection kit at $89.16 and Amazon.ca listed a 10 ft polyurethane kit at $321.64. That is materials only, with no labour, no inspection and no contractor warranty behind it.
• Insist the warranty is in writing and ask whether it transfers on sale. DryShield publishes a lifetime transferable warranty, so ask competitors to match the paperwork, not just the price.
• Fix the outside water first where it is cheap. Downspouts, grading and window wells are far cheaper than the excavation work that repeated leaks eventually force.

Every price on this page comes from a named Canadian source, and where sources disagreed we widened the range rather than pick a favourite. Here is how WaterproofingIndex reconciled the numbers.

• Published GTA prices for the same repair spread very wide. Nusite Group quotes $300 to $800 per crack and Gamcon quotes $400 to $800, while DryShield publishes $750 to $1,500 and Aquatech Waterproofing publishes $1,500 to $3,000 for foundation crack repair. Leaquida budgets about $1,500 to $2,200 for a straightforward accessible interior injection. Treat any single published number as one company's list price, not a market rate.
• Where a source published a range but named no single most likely price, the typical column above repeats that source's own lower bound. No midpoints were calculated and no two sources were averaged together.
• Injection is priced per crack, not per linear foot. DryShield states that most residential crack injection projects are priced per crack based on standard wall conditions, and that a single injection usually takes a few hours. Per linear foot pricing shows up only when the fix moves to exterior excavation or an interior drainage system.
• The method changes the price. Polyurethane expands and stays flexible, so it is the leak-stopping choice. Epoxy cures rigid and is used when strength restoration is the goal. DryShield prices polyurethane at $750 to $1,000 and epoxy at $750 to $1,500. Ontario Foundations prices polyurethane at $400 to $800 and epoxy at $500 to $1,200.
• Several cracks are usually handled in one visit. DryShield notes that a single crack injection takes about 1 to 2 hours, so several cracks can usually be sealed in one visit, and mentions multi-crack packages with volume discounts without publishing the discount amount. Ontario Foundations says most homes have 1 to 3 cracks needing repair, with an average total project cost of $800 to $3,500.
• Injecting from inside is far cheaper than digging. RCC Waterproofing prices exterior waterproofing, which includes exposing the foundation and repairing the crack, at $50 to $300 or more per linear foot, and Aquatech Waterproofing says exterior excavation for foundation repair typically starts at $15,000.
• A leaking crack is not always just a crack. Leaquida notes that a horizontal line or mild inward bow points to lateral pressure, which moves the job to carbon fibre straps or anchors at roughly $7,500 to $15,000 or more. Ontario Foundations prices carbon fibre staple reinforcement at $800 to $2,500 per crack on top of the injection.
• DIY kits are materials only and cover a short crack. The DRICORE crack injection kit at Home Depot Canada was listed at $89.16 each and marked out of stock online at the time of checking. A 10 ft Hydra Stop 300 polyurethane kit on Amazon.ca was $321.64. Sika Canada's SikaFix Kit page lists a 250 mL polyurethane grout cartridge, 3 bags of quick-set mortar and 20 injection ports, enough for a typical crack 2.4 m (8 ft) long, 200 mm (8 in) deep and 3 mm (1/8 in) wide, but publishes no price.
• HomeStars cost guides for basement waterproofing and foundation crack repair were requested but returned HTTP 403 and could not be read, so no HomeStars figure appears in this guide.
• All figures on this page are Canadian dollars taken from Canadian pages. No United States cost guides were used.
