Our Services

At OnlyBASEMENTS, we specialize exclusively in major basement renovations—projects that go far beyond surface-level upgrades. From structural transformations like underpinning and waterproofing to the creation of fully finished living spaces or legal secondary suites. Our work is driven by thoughtful design and expert craftsmanship. We bring together architecture, engineering, and construction under one roof to ensure a seamless and sophisticated result.

Basement Finishing

We believe that a professionally finished basement not only adds significant livable square footage but also enhances your home’s functionality and increases its resale value. Whether you envision a cozy family lounge, a guest suite, or a legal rental apartment.

 

Underpinning & Waterproofing

Underpinning is the process of safely lowering your basement floor to increase ceiling height, improve functionality, and new possibilities for your living space. The process involves digging a sequence of carefully planned holes beneath the existing foundation walls.

 

Legal Rental Units

With over a decade of experience in Toronto’s established neighbourhoods, we handle the lifecycle of legal suite projects. Our integrated team—covering architectural, structural, and construction—ensures you work with one accountable company from start to finish.
