How Much Does Concrete Repair Cost in Toronto in 2026?

Last updated: By ConcreteFinder Research Team

Foundation crack injection costs about $600 to $1,000 for polyurethane and $600 to $1,500 for structural epoxy per crack in Toronto, according to Dryshield. Resurfacing a sound slab runs $4 to $10 per square foot, roughly half the $12 to $18 of replacement. Slab leveling costs $3 to $6 per square foot for mudjacking, and parging runs $3 to $8.

What does concrete repair, leveling and parging cost?

ConcreteFinder compiled this table from 10 named Canadian sources; where they disagreed, we widened the range rather than pick one.

What drives the price?

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

  • Crack length, width, and whether it is actively leaking (poly vs epoxy choice)
  • Finished vs unfinished basement - drywall removal and restoration is quoted separately
  • Whether old failed parging must be stripped before recoating ($8–$18/sq ft vs $3–$8 new-over-sound)
  • Structural condition of the existing slab - overlays only work over sound concrete
  • Void size and slab thickness for lifting jobs (foam volume drives polyjacking cost)
  • Decorative finish level: stamped, coloured, or Graniflex overlays add $2–$5+/sq ft over basic
  • Site access (rear yards, tight lots, below-grade walls) and demolition/disposal needs
  • Minimum mobilization charges (~$500–$900) that dominate pricing on small single-item repairs
  • Bundling multiple cracks or slabs in one visit reduces per-unit cost

What's specific to Ontario and Toronto?

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: Ontario's 13% HST applies to the full contract (labour + materials) for concrete repair. Contractor quotes are commonly given pre-HST - confirm whether a quote is 'plus HST' before comparing.
  • Permits: routine repair work (parging, crack injection, resurfacing overlays, slab lifting) on private property does not need a Toronto building permit, but underpinning or structural foundation alteration requires a building permit with drawings sealed by a professional engineer.
  • Right-of-way rules: widening a driveway, changing a curb cut, or building a front-yard parking pad involves the City of Toronto right-of-way and zoning bylaw 569-2013 - it requires city approval/licensing through Transportation Services, and many downtown lots are ineligible for pad licences entirely. Repairing an existing driveway in place needs no approval.
  • Seasonality: the practical exterior season for parging, overlays, and pours is roughly April–November. CSA A23.1 cold-weather concreting rules (heating, hoarding, protection below 5°C) make winter exterior work costlier, and most GTA parging crews stop when overnight temperatures drop below freezing since fresh parge coats fail if they freeze before curing.
  • Freeze-thaw: Toronto's freeze-thaw cycles are the root cause of most spalling and parging failure - single-coat consumer-grade parging typically fails within 2–3 winters (Alasya Construction), which is why properly prepped two-coat systems quote higher.
  • Slab lifting timing: polyurethane foam lifting can be done in colder temperatures than mudjacking, but leveling is best scheduled after spring thaw so slabs are lifted against settled, not frost-heaved, grade.
  • Salt damage: de-icing salt accelerates surface spalling on GTA driveways and steps; contractors commonly recommend a penetrating sealer ($2,000–$4,000 on large commercial jobs per Nusite Group, a few hundred dollars residential) after any resurfacing.

How can I pay less?

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

  • Bundle repairs into one visit - multi-crack injection packages and multi-slab lifting discounts beat the ~$500–$900 per-visit minimum every time.
  • Resurface rather than replace when the slab is structurally sound: $4–$10/sq ft overlay vs $12–$18/sq ft tear-out saves 40–60%.
  • Choose mudjacking ($3–$6/sq ft) over polyurethane ($5–$25/sq ft) for low-stakes slabs like a back patio; save foam for driveways and garage slabs where permanence matters.
  • Book shoulder-season (early spring or late fall) - GTA concrete crews discount to fill the calendar outside the May–September rush.
  • Fix small: a $250–$600 parging patch or $600–$1,000 crack injection now prevents a $3,500–$7,000 re-parge or $3,000–$5,500 exterior excavation later.
  • Get three quotes minimum - documented GTA spreads for identical work (e.g., $600 vs $3,000 for one crack injection) are the widest of any home-repair trade.
  • Ask whether the quote includes HST and interior finishing restoration; two 'identical' quotes can differ 13%+ on tax treatment alone.

How did we research these numbers?

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 ConcreteFinder reconciled the numbers.

  • All price rows come from Canadian sources quoting CAD; US cost guides that appeared in search results (Angi, HomeAdvisor, HomeGuide, Sundek) were excluded rather than converted to avoid USD contamination.
  • Parging sources conflict: GTA Masonry quotes $3–$8/sq ft standard while Alasya Construction quotes $6–$12/sq ft for a two-coat premium system with acrylic finish adding $3–$5/sq ft. Both rows are shown separately; budget $5–$8/sq ft for a defensible mid-range. GTA Masonry also quotes full removal-and-recoat at $25–$55 per linear foot.
  • Crack injection sources conflict: Dryshield and RenoQuotes put interior injection at $500–$1,500 per crack, while Leaquida Waterproofing (Toronto, 2025) quotes $1,500–$3,000 per interior seam and $2,500–$4,500 for diagonal cracks needing carbon-fibre staples. Expect quotes across the full $500–$3,000 spread; structural add-ons (carbon fibre, bowing walls) push jobs to $7,500–$15,000+.
  • Toronto slab-lifting contractors (Sanremo Poly-Foam, EcoStar) do not publish per-sq-ft rates; the $3–$6 mudjacking and $5–$25 polyjacking figures are from Projack Canada (Edmonton, CAD) and align with Toronto Concrete Repairs' $1,200–$2,500 per-job Toronto figure. Polyurethane runs roughly 2–3x mudjacking upfront but cures in ~15 minutes and is generally considered permanent.
  • Resurfacing overlay quotes cluster tightly: Nusite Group $4–$8/sq ft, Toronto Concrete Repairs $7–$10/sq ft (overlay page) and $6–$12/sq ft (standard resurfacing), versus $12–$18/sq ft for full tear-out and replacement - overlays save roughly 40–60% when the base slab is structurally sound.
  • Most GTA concrete contractors carry an effective minimum call-out of roughly $500–$900, so tiny repairs (one hairline crack, one step edge) rarely price below that regardless of per-unit rates.
  • Per-project resurfacing benchmark: a porch/walkway surface resurfacing job in Toronto runs $2,500–$4,500 (Toronto Concrete Repairs); full porch restoration $5,000–$8,000.

Frequently asked questions

How much does it cost to fix a foundation crack in Toronto?

Interior crack injection is the standard fix: Toronto's Dryshield quotes $600–$1,000 per crack for polyurethane (leak-stopping) and $600–$1,500 for structural epoxy, and RenoQuotes' Canada-wide range is $500–$1,500. Some Toronto firms quote $1,500–$3,000 per seam, so get two or three quotes. Exterior dig-and-seal repairs run $3,000–$5,500 per crack.

What does parging cost per square foot in Toronto?

GTA quotes span $3–$8 per square foot for standard parging and $6–$12 for a premium two-coat system with proper surface prep; an acrylic finish coat adds $3–$5 per square foot. Small patches under 10 sq ft run $250–$600, while fully re-parging a detached Toronto home's foundation typically costs $3,500–$7,000.

Is it cheaper to resurface a concrete driveway than replace it in the GTA?

Yes, substantially. A resurfacing overlay costs about $4–$10 per square foot installed in the GTA, versus $12–$18 per square foot for full tear-out and replacement - roughly half the cost or less. The catch: the existing slab must be structurally sound. If it's badly cracked, heaved, or settling, an overlay will fail and replacement is the better spend.

Which is cheaper, mudjacking or polyurethane foam lifting?

Mudjacking is cheaper upfront at roughly $3–$6 per square foot in Canada, while polyurethane foam lifting runs $5–$25. Foam costs roughly double but cures in about 15 minutes, adds far less weight to the soil, and is generally considered permanent. A typical Toronto residential leveling job (sunken walkway or porch slab) lands around $1,200–$2,500 either way.

How much does it cost to repair spalling concrete steps or a porch in Toronto?

Moderate spalling repair - grinding out crumbling concrete, reinforcing, and refacing with repair mortar or an overlay - runs $1,000–$1,500 in Toronto per Toronto Concrete Repairs. Individual step repair or replacement costs $300–$800 per step. If spalling covers most of the surface, a full resurfacing at $2,500–$4,500 usually beats patching piecemeal.

Do I need a permit for concrete repair in Toronto?

Usually no. Parging, crack injection, resurfacing, and slab lifting on your own property don't require a building permit. You do need one (plus engineered drawings) for structural work like underpinning or foundation replacement, and any work in the city right-of-way - widening a driveway curb cut or installing a front-yard parking pad - needs City of Toronto approval, with pad licences often costing several hundred dollars.

How much does it cost to lift one sunken sidewalk slab section?

A single sunken walkway section typically costs $250–$450 to lift, with whole-walkway jobs averaging $500–$750, per Projack Canada's 2025 Canadian pricing guide. Most GTA contractors carry a minimum call-out around $500–$900, so bundling several slabs into one visit - front walk, patio, and garage apron together - gets you the best per-slab rate.

Why do Toronto concrete repair quotes vary so much for the same job?

Because scope hides below the surface: a $600 crack injection becomes $2,500+ if the basement is finished, the crack is structural, or carbon-fibre reinforcement is needed, and parging jumps from $3–$8 to $8–$18 per square foot when old failed parging must be stripped first. Toronto's freeze-thaw climate also punishes cheap single-coat work, so premium quotes often reflect prep, not padding.

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?
