Basement Underpinning in Tillsonburg, ON

Tillsonburg is experiencing steady growth and increasing property values, making it a smart location for basement apartment investments. Whether you own an older home on Broadway or a newer build in one of the expanding subdivisions, we can design and build a legal basement suite that meets all building code requirements while maximizing your return on investment.

Many older homes in London have basements with ceiling heights under 6’9”, which doesn’t meet Ontario Building Code minimums for habitable space. Basement underpinning lowers the existing foundation and floor to create the ceiling height you need — typically 8’ or more. This is a specialized structural process that involves excavating beneath the existing footings in carefully sequenced sections, pouring new concrete to extend the foundation depth, and then pouring a new floor slab. Our team has extensive experience with underpinning London’s older housing stock, including homes with stone, block, and poured concrete foundations. Every project is engineered by a licensed structural engineer and inspected at every stage.
