Underpinning & Basement Waterproofing in Toronto's East End
We lower basements, stop leaks and fix foundations in the older homes of Leslieville, Riverdale and East York. Our crew is based right at Gerrard & Broadview.
What We Do
Most East End homes were built before 1960, with brick or block foundations, clay weeping tile and low basement ceilings. That's the work we specialize in.

A Local Crew for Old Toronto Houses
A century-old semi in Riverdale isn't built like a new build in Vaughan. The footings are shallow, the walls are often brick or rubble, and the original drainage is usually long gone. We open it up, show you what's going on, and fix it properly.
- Free inspection and a written quote before any work starts
- Underpinning done in sections so the house stays supported the whole time

Common Questions
Do you offer free estimates?
Yes. We inspect on site for free and give you a written quote before any work starts.
Interior or exterior waterproofing: which do I need?
It depends on your lot and where the water's getting in. Exterior is best when there's room to dig. Interior works on tight semis and row houses where you can't excavate. We'll tell you which one actually makes sense for your house.
How long does underpinning take?
It depends on the size of the basement and how far down we're going. We'll give you a timeline with your quote.
Can you lower my basement for a basement apartment?
Yes. Basement lowering and underpinning are how most older East End homes get the ceiling height a legal basement apartment needs.
