Basement Finishing in Toronto, the GTA & Niagara

Turn unused square footage into the room your home is missing

In the GTA, the basement is usually the cheapest square footage you will ever add - the walls and roof are already there. A finished basement can become a family room, a bedroom, a home office, or a separate suite that pays part of the mortgage.

The work is less about decoration and more about getting moisture, insulation, ceiling height and egress right. We start with what the space can actually become, and tell you honestly if something will not work before you spend on it.

Common questions

Do I need a permit to finish a basement in Toronto?

Yes, in most cases. Finishing a basement usually involves framing, electrical and often plumbing, which require a building permit from the City of Toronto. A basement apartment or secondary suite has stricter requirements still, including ceiling height, egress windows and fire separation. We go through this with you before any work begins.

Is my basement suitable for finishing?

The three things that decide it are moisture, ceiling height and access. We assess all three before quoting, and we will tell you honestly if the space will not work as you are imagining it - that conversation is cheaper before the project than during it.

Can you build a basement apartment or rental suite?

Yes. A legal secondary suite in Toronto has specific requirements for ceiling height, egress windows, fire separation and a separate entrance. We build to those requirements so the suite can be registered, rather than building something that has to be undone later.

How do you deal with basement moisture?

We deal with it before anything is closed up, never after. That means finding the source, addressing it, and using the right insulation and vapour control for a below-grade space. Finishing over a moisture problem hides it for a year and then destroys the finish.
