Typical GTA foundations & underpinning prices for Islington-City Centre West, July 2026. Each row cites its source.
ItemTypical rangeUnitSource
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$480per linear footStrong Basements
Foundation crack repair - structural epoxy injectionDryShield's epoxy tier, for bonding structural cracks where strength restoration is the goal. Same floor as polyurethane, higher ceiling. Neither the $800 floor nor the $2,500 ceiling this guide used to show is on their page.$750$1,500per crackDryShield Basement Waterproofing (Toronto/GTA, 2026)
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$60per sq ftNusite 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$80,000per projectNusite Group (Toronto underpinning contractor)
Structural engineering drawings for underpinning permitStrong Basements' Toronto figure for the engineer to design the underpinning around the home's structure and soil and produce a drawing set for the permit application and construction. Some design-build firms fold it into a project package instead of billing it separately. Neither the $1,500 floor nor the $6,000 ceiling this guide used to show is on their page.$2,000$5,000per projectStrong Basements (Toronto)
City of Toronto minimum building permit fee (2026)A floor, not a range, and not the whole permit cost. The City charges $214.79 minimum on all work in 2026 and then calculates the permit as a service index times floor area; examination and inspection time is $92.79 an hour. Engineering, drawings, revisions and plumbing permits are extra.$214.79$214.79per permit (minimum; underpinning is charged per linear metre on top)City of Toronto Building Permit Fee Schedule
