Basement Finishing in Mississauga
Moisture handled first, then a space you can actually live in.
From the large unfinished basements of Erin Mills and Meadowvale to the older homes near Port Credit, a finished basement adds real living space to a Mississauga home for far less than moving. It only works if the water is handled first. ArchCap finishes basements with the moisture dealt with before anything else.
Moisture comes first
We deal with drainage, vapour and insulation before a sheet of drywall goes up. Skip that step and even the nicest finish fails. We do not skip it.
Built to code, built to live in
A rec room, a home office, an in-law suite, or a bathroom where your home and the City allow it. We handle the permits and build to code, so the space is safe and insurable.

Questions homeowners ask
Do you handle moisture and waterproofing?
Yes, and it comes first. Managing the moisture before finishing is the most important step.
Can you add a bathroom or a separate entrance?
Often, depending on your home and City rules. We will tell you what is possible up front.
Do I need a permit?
Usually, yes. We handle the drawings and the permits as part of the build.
How long does it take?
Most basements run 4 to 8 weeks depending on the work. You get a real timeline before we start.
Do you handle design and permits?
Yes. We handle design, drawings and the permits your project needs, so you are not managing separate people for each step.
Will I get a fixed price before work starts?
You get a written, itemised quote before any work begins, with materials, labour and scope laid out, so there are no surprises at the end.
How long will a renovation take?
It depends on the scope, but we give you a realistic schedule with the quote and keep you posted as the work moves.
Do you clean up after the work?
We hand the space back done and clean, and our own cleaning crews can take it further if you want.
