Basement Underpinning in Aylmer, ON

Aylmer homeowners in East Elgin are adding legal basement apartments to generate income and increase property value. Our team serves the Aylmer area with comprehensive basement renovation services including underpinning older foundations, waterproofing, egress window installation, and full legal suite construction with all necessary permits and inspections.

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.
