| Item | Typical range | Unit | Source |
|---|---|---|---|
| Building permit line as quoted by contractorsWhat a contractor bills for the permit, not what the City charges. Nusite lists it inside a $2,000 to $5,000 permits-and-engineering line, alongside $1,000 to $3,500 for the engineer's assessment and drawings; the direct City of Toronto minimum fee is $214.79. | $1,000–$1,500 | 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 - 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) |
| 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) |
| 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) |
| Structural engineer site inspection / assessmentOpen-ended at the top: SEPCO writes $600 to $1,200+. Covers a site visit, assessment and an optional letter or report. | $600–$1,200+ | per visit | SEPCO Engineering |

A solid Agincourt 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.
