Built for the city’s older housing stock — from century homes to 1960s semis.
A lot of Toronto’s core neighbourhoods — the Annex, Leslieville, the Junction, Riverdale — are full of homes built well before modern waterproofing standards existed. Original weeping tile systems are often 60–100 years old, foundation walls are frequently fieldstone or aging brick, and many owners are underpinning specifically to legally raise ceiling height for a basement apartment. We work within Toronto’s tighter lot access and permitting requirements regularly, so a downtown job isn’t a surprise to us.
Why homeowners in Toronto choose us:
- Experience underpinning older stone and brick foundations, not just standard poured-concrete builds
- Familiarity with City of Toronto permitting for basement apartment and second-suite conversions
- Tight-access excavation experience for narrow, laneway, and semi-detached lots

FAQ
Do I need a permit to underpin my Toronto home?
Yes — underpinning requires a building permit and, in most cases, an engineer’s drawings. We handle the process and coordinate with your engineer.
Can underpinning help me legally rent out my basement?
Often, yes — underpinning is one of the most common ways to meet the ceiling-height requirement for a legal second suite.
