Homeowners pricing foundation and underpinning work here can anchor on two line items: structural engineering drawings for underpinning permit runs $2,000–$5,000 per project (Strong Basements (Toronto)) and structural engineer hourly rate (Toronto/GTA) runs $150–$300 per hour (SEPCO Engineering). Pricing across Toronto usually lands near the GTA midpoint. Add 13% HST before comparing quotes.
| Item | Typical range | Unit | Source |
|---|---|---|---|
| Basement underpinning - turn-key project (engineering, permits, waterproofing, plumbing, new slab)Strong Basements' all-in figure for a basement-lowering project, the same sentence that carries their per-linear-foot rate. Their worked example is a 600 sq ft basement lowered by 2 feet at $62,900 all in. The $50 floor and $105 ceiling this guide used to show are not on their page. | $80–$100 | per sq ft | Strong Basements (low end: Nusite Group) |
| Structural engineer hourly rate (Toronto/GTA)An hourly consultation rate for advice only. SEPCO puts Toronto and the GTA at the top of the provincial band, $150 to $300 per hour, for highest demand and fastest turnaround. | $150–$300 | per hour | SEPCO Engineering |
| Underpinning a 1,000 sq ft basement lowered by 2 feet (total project)Nusite's worked example at their own $50 to $80 per square foot underpinning rate, over a four to ten week timeline. Permits, engineering, waterproofing, plumbing and finishing are all priced on top. | $50,000–$80,000 | per project | Nusite Group (Toronto underpinning contractor) |
| Bench footing - priced by floor areaBench footing keeps the existing footing and steps the new floor in from the wall, so it is cheaper than underpinning but gives up perimeter floor area. Nusite's timeline is four to eight weeks. | $35–$60 | per sq ft | Nusite Group |
| Basement underpinning - structural work onlyStrong Basements' Toronto average for the structural work alone. Elsewhere on the same page they put the market rate for a professionally managed, fully insured project at $350 to over $600 per linear foot, with crawlspaces often at the higher end. Cost varies with soil conditions, depth of lowering, the underpinning method (non-shrink, overpour, L-shape, bench footing, engineered bench) and structural requirements such as load posts and beams. The flat $650 ceiling this guide used to show is not on their page. | $350–$480 | per linear foot | Strong Basements |
| Exterior waterproofing, as part of a basement-lowering projectNusite prices this only where exterior work is needed; an interior waterproofing system on the same job is $5,000 to $8,000, and the waterproofing line as a whole is $5,000 to $15,000. | $10,000–$15,000 | per project | Nusite Group (Toronto underpinning contractor) |
Every foundation contractor here is ranked by the same public formula: a review-volume-weighted Google rating, what the company states on its own site, and the state of its record. The median company here carries 26 Google reviews. That keeps the list of 29 honest, and no spot is ever paid for. Read our full methodology.
We track 29 companies in the area this July 2026, at an average Google rating of 4.93★ and a median of 26 reviews each. That is enough Toronto choice to line up three or more quotes before you commit.
Always. Lowering a basement by underpinning or bench footing is structural: it needs a building permit, stamped engineering under the Ontario Building Code, and staged municipal inspections. Expect a longer, controlled Toronto schedule than flatwork, though the below-grade nature means it is not limited to the pour season.
Yes. A free on-site estimate is standard among local foundation contractors. ConcreteFinder lists the Toronto companies with their public phone number and website, so you can line up two or three visits yourself and compare scope side by side.
No, placement can't be bought. We rank the 29 Toronto foundation contractors here on a published score out of 100: reviews with volume weighed, what the company states on its own site, and the state of its record. In Toronto, 96% of rated companies clear 4.8★, so small gaps matter.
A Toronto homeowner can anchor on this line item: bench footing - priced by floor area, $35–$60 per sq ft (Nusite Group). Quotes there usually track that GTA range. Add 13% HST, then compare quotes against the full cost guide.
A solid Toronto quote itemizes site prep, mix and thickness, reinforcement, finish, jointing and disposal, then the payment schedule and warranty. A vague one-line price is a red flag, so compare like-for-like scope across three bids.
