Basement Lowering

Turn dark, low-clearance cellars into full-height, modern rental suites or family rooms.

Most older Toronto homes — heritage detached houses, Victorian semis, and narrow downtown townhouses — were built with cellars barely six feet high. Lowering the floor is the only way to unlock that footprint without touching your lot coverage, setbacks, or the exterior character of the property.

We lower the slab in a fully engineered sequence, remove and haul the excavated soil, and rebuild with a new reinforced slab, drainage layer, and thermal break beneath. The result is a dry, warm, full-height level that satisfies Ontario Building Code requirements for habitable space and secondary suites.

Our 4-Step Structural Process

1. Site Inspection & Engineering

We assess your foundation, soil, and load paths on site, then engage our structural engineer.

2. Permitting & Structural Drawings

Stamped drawings and City of Toronto permits are handled end to end before a shovel moves.

3. Sequential Excavation & Pour

Pin-by-pin excavation and reinforced concrete pours keep the structure fully supported throughout.

4. Final Inspection & Sign-Off

Engineer and municipal inspections, cleanup, and a written workmanship guarantee.

What Toronto Homeowners Say

Ken's crew lowered our 1890s Cabbagetown basement by three feet. Meticulous sequencing, permits handled, and our heritage brick came through untouched.
