Basement Renovations

Transforming unfinished basements into legal suites, family rooms, home gyms, and income-generating spaces.

A finished basement adds living space, property value, and often a significant income stream. Whether you want a legal second suite, a family entertainment room, or a home gym, we design and build basements that are properly waterproofed, code-compliant, and built to last.

Essential Considerations

Waterproofing & Moisture Control

Basement moisture is the root cause of most failures. We address drainage, vapour barriers, and waterproofing before any framing or finishes go in.

Legal Suite Requirements (OBC)

Legal suites require minimum ceiling heights, egress windows, fire separations, and separate mechanical systems. We design to code from day one.

Ceiling Height & Underpinning

Low ceilings can often be addressed through underpinning or bench footing. We evaluate options and costs honestly before you commit.

Permits & Inspections

Basement renovations frequently require building permits, especially for suites, structural changes, and new plumbing. We handle the full permit process.

Our Basement Renovations Process

  • Assessment & Design

    We assess existing conditions (moisture, heights, mechanical), define the scope, and produce a layout that maximizes the space.



  • Permits & Material Planning

    We handle permit submissions, confirm material selections, and schedule trades so the build starts without delays.



  • Waterproofing & Rough-Ins

    We address moisture first, then complete structural, plumbing, electrical, and HVAC rough-ins before closing walls.



  • Finishes & Inspection

    We install drywall, flooring, cabinetry, fixtures, and trim, then complete all required inspections and final walkthrough.

Basement Renovations FAQ

Do I need a permit to finish my basement?
Most basement finishing projects require a permit — especially if you're adding a bathroom, creating a rental suite, or making structural changes. We identify permit requirements upfront.
How much does a basement renovation cost in Toronto?
A standard finished basement runs $50,000–$100,000+. A legal suite with separate kitchen and bathroom typically costs $80,000–$130,000 depending on existing conditions and finishes.
What makes a basement suite 'legal' in Ontario?
Legal suites require OBC-minimum ceiling heights (1.95m), egress windows, fire-rated separation, a separate entrance, and independent mechanical systems. We build to these standards.
Can you fix an existing damp or leaky basement?
Yes. We address interior waterproofing (drainage channels, sump pumps, vapour barriers) and can coordinate exterior waterproofing where needed before finishing the space.
