Underpinning for Whitby homes
Whitby homeowners increasingly look to their basements for additional living space — home offices, bedrooms, gym spaces, and in-law suites. Many Whitby homes from the 1990s–2000s have basement ceiling heights that limit how the space can be used. Underpinning solves this by excavating below the existing foundation floor and extending the ceiling height to 8 feet or more. We offer competitive Durham Region pricing on all Whitby underpinning projects.

- Town of Whitby and Durham Region permit requirements
