Scarborough's post-war bungalow and detached stock is well-suited to underpinning for legal apartments. Larger lots, accessible permits, City of Toronto framework. Toronto Basement Underpinning delivers basement underpinning, interior waterproofing, basement finishing, sump pump installation, concrete foundation repair, legal apartment conversions, walkout basements, and permit coordination - full scope, one licensed crew.

The homeowners who contact Toronto Basement Underpinning are usually wrestling with one of these. We solve them properly - not with a quick fix that fails in two years.
Post-war Scarborough bungalows and split-levels in Agincourt, Wexford, and Bendale typically have 6'6"-7'0" original basements. Underpinning to 8'+ enables both finishing and a legal secondary suite.
Scarborough Bluffs-area clay, especially in Cliffside and Birch Cliff, drives active settlement in older detached homes. Patches keep failing because the underlying bearing problem continues.
Original 1960s drainage tile on Scarborough's clay soil is past its life. Every spring melt brings water entry through the wall-floor cove, especially in Bendale and Wexford.
City of Toronto plan review applies to all Scarborough addresses, with Second Suite registration as an extra step for legal apartments. Typical timeline 8-12 weeks. We handle it.
Complete framing, rough-ins, drywall, flooring and trim to convert a raw basement into a legal apartment or luxury living suite. Available in Scarborough as part of our full-turnkey underpinning service.
Exterior stairwell and door opening cut into your foundation wall, engineered to code, permitted, and waterproofed. Creates a private entrance for a legal basement suite or direct backyard access. Available in Scarborough as part of our full-turnkey underpinning service.
Crack injection, footing repair, and structural reinforcement for Toronto homes, with an honest call on when full underpinning is the right answer instead. Available in Scarborough as part of our full-turnkey underpinning service.

Primary plus battery backup sump pump systems sized for Toronto's freeze-thaw water table, eligible for the City of Toronto Basement Flooding Subsidy. Available in Scarborough as part of our full-turnkey underpinning service.
Scarborough projects route through City of Toronto plan review, with the Bluffs-area clay soil profile driving the engineering details on every Cliffside and Birch Cliff site. Plan review typically runs 8-12 weeks, and we sequence the engineer's settlement assessment in the first two weeks so it doesn't extend the timeline.

“Agincourt 1970s detached, the basement was a low-ceiling storage cave. TBU underpinned to 8 feet plus a full waterproofing job, and we built a legal apartment for my parents who came over from Chennai. Tenants happy, basement bone-dry.”

“Bendale Scarborough bungalow, original cinderblock foundation. The crew handled the chronic spring water entry by replacing the perimeter drain during the underpinning. Saved us a separate waterproofing project later.”

“Wexford 1960s split-level. Underpinned the basement, lowered the slab to a real 8'2" ceiling, and finished it for the family. The City of Toronto inspector signed off on the first visit and the warranty paperwork came through fast.”
