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. ### Cramped Ceiling Height 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. ### Cracked Foundation Walls 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. ### Leaking Basement 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. ### Stalled By Permits 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.

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.” Jasmine A. Agincourt, Scarborough “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.” Devon B. Bendale, Scarborough “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.” Anitha K. Wexford, Scarborough Got Questions? ## Common Questions About Our Service Do you serve all of Scarborough? Yes, from Cliffside and the Bluffs east through Wexford, Agincourt, and Highland Creek. Travel time from our Toronto staging yard is 30-45 minutes. How does Scarborough's permit process compare to Toronto? Scarborough is part of the City of Toronto, so permits go through the same Building Department but file at the Scarborough Civic Centre district office. Plan review and fees are identical to the rest of Toronto. Can I add a legal apartment in a Scarborough bungalow? Yes - Scarborough bungalows are ideal candidates. Original ceiling heights (6'8"-7'0") fit the underpinning math, and side-door entrances on many post-war Scarborough builds make legal-apartment compliance straightforward.
