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

This range rests on 6 independent named sources, across 9 priced lines. Every figure was re-read in August 2026 in the source that publishes it, and any figure whose source could no longer be read was removed rather than carried forward. Where two sources disagree, both rows are shown as their own sources published them; nothing is averaged and no range is widened to cover a gap.

Access, depth and scope move foundation crack injection pricing more than anything else in Toronto. Each factor below is one reason two quotes for what sounds like the same job can be thousands of dollars apart.

• 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
• Extras found during the same visit, such as tie-rod holes at $75 to $150 each (DryShield)

Ontario adds 13% HST to every figure on this page, Toronto requires permits for most below-grade structural work, and both change what you actually pay. These are the local rules and subsidies that a national price guide leaves out.

• 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.

Bundling work into one excavation, reusing what is already there, and getting the sequence right are what actually cut a foundation crack injection bill in the GTA. Each lever below is tied to a figure in the table 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 the exterior route runs $50 to $300 or more per linear foot on RCC Waterproofing's own price guide.
• 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 DryShield's 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 was re-read in the page that publishes it, and the sentence carrying it was recorded so the figure can be checked rather than trusted. Where two Canadian sources disagree, WaterproofingIndex shows both rather than averaging them into a number neither company quoted.

• 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. 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.
• 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.
• 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.
• 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.
• 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.

Every picture below was published by the company under it, on its own business listing, and WaterproofingIndex did not take any of them. Each of these companies describes below-grade water work on its own website, which is the same relevance check every profile on this site publishes. They are still not all the same kind of picture: some show a floor opened up mid-job, some show a truck or an office with the company's sign on it. None has been checked against a job in your area, and none is evidence of a price. They are here because a company that publishes its own excavation is showing you something a quote cannot.

The table above is the market. These calculators put your own basement into it, and they add the HST and any City of Toronto subsidy that applies.

• Price it by crack, tie-rod holes included

These are the words that appear on a foundation crack injection quote without being explained. Each one changes what you are buying.

crack injection

Filling a foundation crack under pressure through ports drilled along it, with polyurethane where the aim is to stop a leak or epoxy where the aim is to bond the concrete back together.

parging

A thin cement coat applied to the exposed face of a foundation wall above grade. It is protective and cosmetic, not waterproofing, and it is priced by the square foot or by the side of the house.

weeping tile

The perforated drain pipe laid in stone alongside a foundation footing. It has nothing to do with tile: the name is from the clay pipe sections originally used. It collects groundwater before it reaches the wall and carries it to a storm connection or a sump pit.

underpinning

Deepening an existing foundation by excavating and pouring new footings in sequenced sections beneath the old ones. It is how a basement gains height without moving the house, and it is structural work that needs engineered drawings and a permit.

Most of the money on a foundation crack injection quote is decided before any number is written down, by which of two methods the company is proposing. These side by side pages are built from the same price rows as the table above.
