About Legal Basements London

15+ years transforming basements across London, Ontario into legal, livable, income-generating spaces.

Our Story

Legal Basements Londonwas founded to solve a specific problem: homeowners in London and Southwestern Ontario want to create legal basement apartments but don't know where to start. The permit process is complex, Ontario Building Code requirements are strict, and finding a contractor who truly understands second suite construction can be difficult.

With over 15years of hands-on construction experience and deep knowledge of Ontario's building code requirements for secondary suites, we've helped homeowners across London, St. Thomas, Woodstock, and surrounding communities transform their basements into legal, income-generating apartments.

We're not a general renovation company that happens to do basements. Basements are all we do — and that specialization shows in every project. From underpinning older foundations to meet ceiling height requirements, to designing efficient suite layouts that maximize rental value, to navigating the municipal permit process, we bring focused expertise that generalist contractors simply can't match.

Every project starts with a free, no-pressure consultation where we assess your basement's potential and give you an honest evaluation of what's possible, what it will cost, and how long it will take. No surprises — just straight answers from people who do this work every day.
