Basement Underpinning in Dorchester, ON

Dorchester’s growing community just east of London is home to many properties with untapped basement potential. Whether you’re looking to finish an unfinished basement, add a legal apartment for rental income, or address foundation moisture issues, our team provides professional basement services throughout the Dorchester and Thames Centre area.

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.
