Concrete Repair Plus

Market data, not our rate card

Concrete repair cost in Toronto & the GTA.

28 published market ranges for concrete work across Toronto and the Greater Toronto Area, compiled from the Canadian sources named at the bottom of this page. Every figure is before HST. Where only United States data exists, we say so instead of converting it and calling it a Toronto price. Verified September 2026.

How to use these numbers, and how we built them.

Most concrete pricing pages you will find are the same handful of figures restated until they look like a consensus. A good number of them are American data quoted in dollars with nothing converted. So the rule here was simple: Canadian sources for Canadian figures, every publisher named, and anything we could not stand behind left out with the reason given.

A range is not a hedge, it is the truth. Two porches that look identical from the sidewalk can hide very different concrete underneath, and the honest answer to what yours costs is a number produced after somebody looks at it. What a range does is tell you when a quote is outside the market, in either direction.

  • Every figure is pre-HST. Ontario adds 13% on top, as its own line.
  • Units match how the trade quotes. Per square foot for surfaces, per crack for injection, per balcony for balconies, per project where no honest rate exists.
  • Derived figures say so. Where a number is arithmetic rather than a published rate, it is labelled.
  • No self-citation. Nothing here is sourced from this site or from any business connected to it, which would make the whole page circular.
  • Small jobs break the maths. Under about a hundred square feet, read the minimum, not the rate.

GTA market ranges, repair

Repair

Repair work is labour first, materials second, which is why the small-job floor matters more than the square-foot rate on anything under about a hundred square feet.

Concrete repair, general

Quoted per sq ft, plus a small-job minimum

$7 – $15 / sq ft

Also worth knowing
Small jobs carry a floor of $500 – $1,200. Whole projects commonly land at $1,000 – $5,000.
What moves it
Surface patching on one contiguous area sits at the low end. Full-depth work, exposed reinforcing steel, several scattered small areas that each re-incur setup, tight access and winter conditions push to the top.

Spalling and salt scaling repair

Quoted per sq ft

$7 – $15 / sq ft

What moves it
Scaling is a surface failure and repairs at the low end. Spalling with rusting reinforcement inside it has to be opened up, the steel treated and the section rebuilt, which is a different job at a different price.
Basis
The general Ontario repair band, applied to the two failure modes it covers.

Crack repair, slab and flatwork

Quoted per visit

$500 – $1,200

Also worth knowing
Filling a single minor crack rarely passes $300 on its own, which is why crack work is usually bundled.
What moves it
Length, depth and whether the crack is still moving. A crack with a vertical offset or wider than about a quarter inch is telling you the base or the steel has failed, and that is a repair, not a filler.

Foundation crack injection

Quoted per crack

$500 – $1,500 per crack

Also worth knowing
A standard eight-foot vertical crack injected from inside runs $750 – $1,000 in the Toronto area. Exterior excavation to the footing with a membrane is $3,000 – $5,500 per crack. A structural engineer’s assessment, where one is warranted, is $300 – $700.
What moves it
A dry hairline in an unfinished basement is the cheapest version. Active water under pressure, a finished basement that has to come apart and go back together, a run over about eight feet, or a structural epoxy spec all move it up. Additional cracks on the same visit price lower, because the first one carries the setup.

Slab lifting and levelling

Quoted per sq ft of slab lifted

$3 – $6 / sq ft mudjacking, $5 – $25 / sq ft polyurethane foam

Also worth knowing
A Canadian worked example: raising two 10 ft by 10 ft driveway sections with polyurethane runs about $800 – $1,200, so roughly $4 – $6 / sq ft at that volume.
What moves it
Counter-intuitively, a small interior or load-bearing lift often costs more than a large patio lift. Labour is 70 to 80% of the cost, so a big accessible outdoor slab is the cheapest concrete you will ever have lifted.

Foundation parging

Quoted per sq ft, plus a whole-house total

$5 – $12 / sq ft new, $8 – $18 / sq ft where the old coat comes off first

Also worth knowing
A full foundation on a typical GTA detached home, roughly 400 to 600 sq ft of wall, runs $2,500 – $7,000.
What moves it
Removing failed parging is the single biggest swing, because what is behind it is unknown until it is off. Height needing staging, below-grade sections, a textured finish and the tight side-yard access common on Toronto lots all add.

Concrete removal and disposal

Quoted per sq ft

$2 – $7 / sq ft

Also worth knowing
Or a lump sum of $550 – $1,700 for a typical residential slab.
What moves it
A four-inch unreinforced slab with machine access is the low end. Eight to twelve inches, rebar or mesh throughout, hand demolition on a narrow lot and a long haul are the top. Clean concrete is exempt from Ontario’s excess soil rules, but contaminated urban soil underneath can cost more to dispose of than the demolition.

GTA market ranges, coatings, resurfacing and polishing

Coatings, resurfacing and polishing

Across every system in this group the same line decides the price: preparation. A quote that looks low is usually a quote that skipped grinding, crack repair or moisture testing.

Garage floor coating, epoxy

Quoted per sq ft installed

$4 – $8 / sq ft

What moves it
A clean sound slab with a solid colour or light flake is the low end. Grinding off a failed coating, moisture mitigation primer, crack and spall repair, and a single small bay where setup does not scale all move it up.

Source: HomeStars, Coated.ca, GLI Epoxy Flooring

The work explained →

Garage floor coating, polyaspartic or hybrid

Quoted per sq ft installed

$6 – $12 / sq ft

Also worth knowing
Premium polyurea and polyaspartic hybrids reach $9 – $14. A double garage of 400 to 550 sq ft in a full flake system runs $2,800 – $4,500. Metallic finishes are $8 – $15+ / sq ft. Moisture mitigation primer adds $1.50 – $3 / sq ft.
What moves it
The system build and how much slab repair happens first. Polyaspartic carries a premium over epoxy in the GTA for reasons that are about our climate rather than marketing: it tolerates freeze-thaw, resists hot-tire pickup, holds colour under UV and cures fast enough to install in one day and in the cold.

Basement floor coating

Quoted per sq ft installed

$5 – $9 / sq ft

Also worth knowing
A 1,000 sq ft basement in a flake system with a moisture barrier typically comes in at $5,000 – $9,000. Removing existing flooring adds $2 – $4 / sq ft.
What moves it
Basements cost more per square foot than garages, and the reason is moisture. Older Toronto slabs often sit on damp ground with no vapour barrier under them, so testing, mitigation priming and low-clearance grinding all enter the price.

Polished concrete

Quoted per sq ft

$3 – $12 / sq ft

Also worth knowing
Commercial GTA floors run $4 – $9 / sq ft. A basic grind and seal is $3 – $6, a high gloss taken to a very fine grit is $8 – $15, and decorative staining or scoring adds $2 – $10.
What moves it
Two things, consistently: how many grinding passes the target sheen needs, and the condition of the slab. A 5,000 sq ft warehouse floor to a matte finish lands near $4 – $5. A 3,000 sq ft lobby at a high gloss reaches $8 – $10.

Concrete resurfacing and overlays

Quoted per sq ft

$3 – $10 / sq ft basic, $7 – $12 / sq ft decorative

Also worth knowing
GTA resurfacing projects mostly land between $2,500 and $18,000 in total, and resurfacing runs 40 to 60% below tearing out and replacing.
What moves it
Crack and spall repair before the overlay is repeatedly named as the largest variable in a resurfacing quote. Grinding or levelling, multiple colours, hand-applied accents, vertical faces and edges, and a protective topcoat all add.

Micro-topping and microcement

Quoted per sq ft

$20 – $25 / sq ft

Also worth knowing
Minimum order about $3,000. Above 1,000 sq ft it eases to $20 – $22.
What moves it
This is the figure most often quoted wrongly, because a true microcement system, multiple hand-trowelled coats a fraction of a millimetre thick and then sealed, is a different product from a bag-mix resurfacer at a fifth the price. Conflating the two is the commonest error in this category.

Pool deck resurfacing

Quoted per project

$7,000 – $18,000

Also worth knowing
A typical GTA pool surround of 500 to 1,000 sq ft puts that at roughly $10 – $20 / sq ft. Repair alone, on small cracked or spalled areas, starts around $500 – $1,200.
What moves it
Pool decks skew high and the exposure is why: chlorinated water, de-icing salt and freeze-thaw on the same slab. Slip resistance is not optional, so the cheap smooth coatings are out. Coping, steps and raised bond beams are hand work, and many GTA surrounds are reachable only through a side gate.
Basis
The project range is sourced. The per-square-foot figure is derived from it against typical GTA deck sizes, not taken from a published rate.

Patio coating

Quoted per sq ft

$7 – $12 / sq ft

What moves it
A sound slab, one colour and a simple rectangle sit at the bottom. Repair first, a stamped or multi-colour pattern, step nosings and vertical faces, a UV and salt resistant sealer, and restricted rear-yard access move it up.

Source: Artisan Coat, HomeStars

Concrete sealing

Quoted per sq ft

$0.45 – $0.90 / sq ft

Also worth knowing
A typical 400 to 800 sq ft driveway is $160 – $280 including surface prep. Reseal every two to four years in this climate.
What moves it
Watch what is being sealed. Much of the cheap Ontario driveway sealing pricing you will find is asphalt sealcoating, a different and cheaper product. Concrete wants a penetrating silane or siloxane sealer that bonds into the pore structure, because surface films delaminate under freeze-thaw.

GTA market ranges, new concrete

New concrete

New flatwork is the one category where size works strongly in your favour. The same crew, the same truck and the same day cover a small pad and a large driveway, so the small pad carries the whole cost.

New flatwork, plain broom finish

Quoted per sq ft

$6 – $12 / sq ft

Also worth knowing
Small pads are the exception: a 10 ft by 12 ft shed pad works out to $16 – $21 / sq ft. A plain 200 sq ft patio slab at four inches is $1,000 – $2,200 installed.
What moves it
Area and access first. Then thickness and reinforcement, base excavation and imported granular, grade and drainage work, thickened edges, hand-barrowing from the street, and the season.

The work explained →

Driveway replacement, including removal

Quoted per sq ft

$12 – $20 / sq ft

Also worth knowing
A standard residential driveway is $8,000 – $15,000. Supply and place alone on a larger area with no demolition is $8 – $12 / sq ft.
What moves it
Removing a thick or reinforced slab, rebuilding the base, correcting drainage or grade, a decorative finish, City boulevard or curb-cut work, and a winter pour, which adds 20 to 30%.

Source: HomeStars, RedFlagDeals forums

The work explained →

Stamped concrete

Quoted per sq ft

$15 – $30 / sq ft

Also worth knowing
The premium over a broom finish is $5 – $9 / sq ft, so about $1,750 – $3,150 more on a 350 sq ft patio. Elaborate multi-pattern custom work in Ontario is quoted as high as $45.
What moves it
One pattern and one integral colour over a large simple area is the low end. Multiple patterns, hand-applied stain accents, borders and banding, a small or irregular area, and a premium sealer are the top.

Source: HomeStars, MCL Concrete, RedFlagDeals forums

Exposed aggregate

Quoted per sq ft

$10 – $20 / sq ft

Also worth knowing
The premium over a broom finish is $4 – $8 / sq ft. Canada-wide the band is $8 – $15.
What moves it
Premium or imported aggregate, custom blends, and a deep exposure that has to be timed precisely against the weather, which is a genuine scheduling risk here.

Ready-mix concrete, supplied

Quoted per cubic metre

$175 – $225 / m³ in Ontario

Also worth knowing
High-strength 30 to 35 MPa adds $20 – $45 / m³. Air entrainment adds about $12. Delivery beyond 30 km adds $8 – $15 / km. A short-load surcharge of $50 – $80 / m³ applies below the three cubic metre minimum, and a winter surcharge of $20 – $40 / m³ runs November to March.
What moves it
This is the material line inside every pour above. It is worth knowing because it is the one input with published price lists, and because the mix your job actually needs is usually not the cheapest one on the list.

GTA market ranges, structures and site work

Structures and site work

Formed structures do not price by slab rates. A step is a small building, and the number comes from step count, footings, railings and geometry rather than from area.

Porch and step repair

Quoted per job

$500 – $2,500

Also worth knowing
Ontario small jobs carry a $500 – $1,200 floor. Minor resurfacing and section work runs $1,000 – $2,500. A full demolition and re-pour is a different project, priced to the structure.
What moves it
One or two cosmetic spalls with the risers sound is the low end. Demolition and re-pour with footings below frost, railing removal and re-anchoring, a landing tied into the house, and curved or wrap-around geometry are separate work.
Basis
The Ontario small-job and section-work bands. We do not publish a per-step replacement figure, see below for why.

Retaining wall, segmental block

Quoted per sq ft of wall face

$50 – $90 / sq ft of face

Also worth knowing
Across all wall types in Ontario the band is $40 – $150. Engineering fees, where a wall needs a stamped design, are $1,500 – $3,500. Drainage stone and perforated pipe add $5 – $10 per linear foot.
What moves it
Height is the master variable, because past a certain point a wall needs an engineered design, a permit and geogrid reinforcement. Then curves and corners, steps and caps, tiers, surcharge loading from a driveway above, poor soil, groundwater, and removing a failed wall first.

Basement egress window, new cut

Quoted per window

$3,500 – $8,000

Also worth knowing
Including a standard casement window, the window well and the permit. The permit itself is $100 – $300.
What moves it
An existing opening with a steel well and no drainage work is the cheap version. A new cut through the foundation, excavation, a drainage tie-in, a concrete or masonry well and egress code compliance are the expensive one.

GTA market ranges, commercial and reserve-fund benchmarks

Commercial and reserve-fund benchmarks

These are third-party lifecycle benchmarks, published for reserve-fund planning rather than as quotes. Commercial and condominium scopes are bid after a site assessment, so treat them as planning figures, not prices.

Parking garage waterproofing repairs

Quoted per sq ft of deck

$15 / sq ft

Also worth knowing
Modelled at years 20 and 40 of a garage’s life.
What moves it
The Canadian Condominium Institute normalized three dozen real Ontario projects to Q2 2023 Greater Toronto pricing using the Statistics Canada building construction price index, then compared them against Altus replacement values. It is the best-sourced figure on this page.
Basis
Stated on a Q2 2023 basis. Ontario non-residential prices have risen modestly since, so read it as a floor rather than a current quote.

Parking garage major rehabilitation

Quoted per sq ft of deck

$40 / sq ft

Also worth knowing
Concrete repair plus waterproofing, modelled at year 35. Complete replacement is $250 / sq ft. Independent GTA restoration contractors put structural restoration at $15 – $40+ / sq ft, which is consistent.
What moves it
Scope growth is the norm: delaminated areas are found once the membrane is off. Post-tension remediation, multi-level staging and parking relocation, shoring, and noise restrictions in an occupied building all add.
Basis
Q2 2023 basis, as above.

Balcony concrete repair

Quoted per balcony

$800 – $2,500 minor, $3,000 – $7,000 moderate, $8,000 – $20,000+ severe

Also worth knowing
Minor is surface patching. Moderate includes waterproofing. Severe is structural repair with a new membrane.
What moves it
Access is the largest single driver: a swing stage changes the economics of the whole job. Then slab-edge repair with corroded reinforcement, full membrane and topping replacement, railing removal and re-anchoring, and how long the work was deferred. Per-unit cost drops sharply with the number of balconies in one program.

Annual garage maintenance budgeting

Quoted per square metre per year

$1 / m² in good to fair condition, $4 / m² for a rehabilitation program

What moves it
These are budgeting benchmarks rather than repair unit prices, and mixing the two is a common error in reserve-fund discussions.

The gaps, stated

Seven numbers we will not publish, and why.

These are the figures most likely to be wrong on any concrete pricing page, because the United States data exists and the Canadian data does not. Filling the gap with a converted American number is how bad pricing spreads. If you came here looking for one of these, the honest answer is the reason it is missing.

Crack repair by the linear foot

No credible Canadian source publishes a per-linear-foot crack rate. The per-foot figures circulating online are United States data. Canadian contractors quote per crack, because the first crack carries the visit and the setup.

Poured concrete step replacement, per step

Every per-step figure we could find is United States data, or is for natural stone and interlock steps rather than poured concrete. We would rather say so than convert a US number and call it a Toronto price.

Trip hazard grinding, per linear foot

The $25 to $50 per linear foot figure in circulation is United States data. Ontario work is quoted per site visit, and the standard that applies here is the Accessibility for Ontarians with Disabilities Act, not the American one.

Industrial floor joint repair, per linear foot

The available figures are United States industry benchmarks. Canadian industrial work is quoted per project after a site walk, which is also how it should be bought.

Slab lifting by the injection hole

Pricing per hole is a United States convention. Canadian levelling contractors quote by the area lifted.

Sidewalk remove and replace, as a published rate

There is no Canadian published rate for it. What we show instead is the arithmetic from two figures that are sourced here: removal at $2 – $7 plus new flatwork at $6 – $12, so roughly $8 – $19 per square foot. Note that the City of Toronto measures sidewalk work by area in square metres, not square feet, so municipal and commercial quotes will not look like this.

The height at which a retaining wall needs a permit

It is commonly stated as one metre of exposed height. We have not verified that against the Ontario Building Code or a Toronto bylaw, so we are not going to state it as fact. Ask your municipality before you design a wall around it.

Why the range is wide

Five things that move every GTA concrete price.

Labour, which is most of it

Labour is 70 to 80% of the cost on repair-type concrete work. The Government of Canada Job Bank puts concrete finisher wages in the Toronto region at $28.80 low, $43.58 median and $47.00 high per hour. The Toronto median sits above the Ontario high end, which is the cleanest single piece of evidence that GTA work costs more, and it comes from the federal government rather than from a contractor.

Job size, which cuts both ways

A 120 sq ft shed pad prices at $16 to $21 a square foot while a 600 sq ft driveway prices at $8 to $12. Same crew, same truck, same day. Mobilization, forming and finishing time barely scale down, so per-square-foot rates mislead badly on small jobs. This is also why the small-job minimum exists.

The season, which is half the year

CSA treats any period at or below 5°C as cold-weather concreting, and in the GTA that runs roughly late October to early April. Concrete has to be placed at a minimum of 10°C and protected for the curing period. Winter pours need special mixes, heated enclosures and blanket curing, adding 20 to 30%, and ready-mix carries a $20 to $40 per cubic metre winter surcharge from November to March. A six-month effective season also compresses demand, which is why spring booking is tight.

The specification, which is not optional

Exterior GTA flatwork exposed to de-icing salt has to meet CSA A23.1 exposure class C-2: 32 MPa at 28 days, a water-to-cement ratio at or below 0.45, and 5 to 8% air entrainment. That covers driveways, garage aprons, sidewalks and exterior steps. The air entrainment is the part that actually buys freeze-thaw durability. High-strength mixes add $20 to $45 a cubic metre and air entrainment about $12, so a correctly specified pour is not the cheapest quote you will get.

Access and preparation

Material pumped off the street costs less than material barrowed through a side gate, and a great many Toronto lots only allow the second. Preparation is the line most often missing from a cheap quote: grinding, crack repair and moisture testing are what separate two numbers that look like they are for the same job.

Tax and minimums

The 13% and the floor, which is where budgets break.

Ontario HST is 13%, and every figure on this page is before tax. That is how contracting quotes are written here: the contract price, then HST as its own line underneath.

Concrete repair, resurfacing, coating and replacement on a home is fully taxable. The HST new-housing and substantial-renovation rebates are a separate mechanism and do not apply to repair work, which is a distinction people conflate often and expensively.

A contractor billing more than $30,000 over four quarters has to register for and charge HST. A quote with no HST line from a very small operator may mean they are under that threshold. It may also mean the tax is coming later.

Forgetting to budget the 13% is the most commonly cited reason a concrete budget comes up short.

Published minimum charges, GTA concrete trade

Ontario concrete repair, small-job floor
$500 – $1,200
Sidewalk sections and minor resurfacing
$1,000 – $2,500
Microcement and micro-topping, GTA
about $3,000 minimum order
Crack injection
the first crack carries the visit; extra cracks the same day price lower, with volume pricing from three up

None of these is a contractor being difficult. Labour is 70 to 80% of the cost on repair work, and the truck, the crew and the day are the same whether the patch is four square feet or forty.

Where prices are going

2026, honestly: down on paper, not in the driveway.

The big-project indices for Toronto are flat to slightly down

Statistics Canada’s building construction price index put Toronto residential at +0.1% in the first quarter of 2026 and down 0.8% in the second, making Toronto one of only three census metropolitan areas to decline. Altus Group’s 2026 Canadian Cost Guide, built on 6,500 projects, found Toronto one of only two major Canadian markets where construction costs came down, while Calgary, Edmonton, Montreal and Winnipeg all rose 4% or more.

That is the condo slump, not the repair market

Altus attributes the decline to a drop in high-rise and condominium building activity leaving contractors available. It says nothing about small residential repair, where labour is most of the cost, GTA concrete finisher wages have kept rising, and the material carries its own annual escalator. Expect small-job repair pricing to be flat to modestly up, not down. Any page telling you concrete repair got cheaper in Toronto this year is reading a large-project index and hoping you will not check.

Steel is the 2026 pressure

Canada imposed 25% tariffs on steel derivative products from 26 December 2025, and most steel tariff remissions expired on 31 January 2026. Reinforcing steel is the input to watch this year, which matters most on structural repair and anything with rebar in it.

Ontario non-residential has kept climbing

The Ontario Construction Secretariat recorded non-residential construction prices up 4.5% year over year in the fourth quarter of 2025 and 3.7% in the first quarter of 2026, with Toronto below the provincial average at 2.9%. Commercial and condominium work is priced against that, not against the residential index.

1 · What are we looking at?

Checkable

Every source, named.

Institutional and national sources first, then Ontario and GTA operators who publish real figures. United States cost guides were read while compiling this and are deliberately not cited for any Canadian range, because the gap between the two markets is large enough to make a converted figure misleading. Last verified September 2026.

Two notes on limits, because a sources list without them is decoration. The parking garage lifecycle figures are published on a second-quarter 2023 basis and Ontario non-residential prices have risen since, so read them as a floor. And the pool deck per-square-foot figure is derived from sourced project totals against typical GTA deck sizes, not lifted from a published rate.

Our own published bands, and the documented jobs behind them, are on the pricing page.

FAQ

Concrete cost questions, answered straight.

Moderate concrete repair across the GTA runs about $7 to $15 per square foot, with a small-job floor of $500 to $1,200 because mobilization and crew time do not scale down. Whole repair projects commonly land between $1,000 and $5,000. Every figure here is before HST, which is 13% in Ontario and charged on top.
