Design-build renovations since 1996
Design, permits, construction and final inspection handled in-house, on a written scope with no last-minute add-ons. The crew that builds them is the same one behind our whole-home projects.



A finished basement is framing, structure, plumbing, electrical, usually a bathroom, then flooring and finishing — sequenced in one space, which is why it takes two to three weeks on site rather than months. The estimate starts with a measure, a floor plan and a 3D sketch of the finished space, then an itemised price based on square footage, so you see the layout before you commit to it. Design, permits, construction and final inspection are handled in-house.

Basement projects are quoted and built under FinishedBasement.ca — the same company, ISM Renobuilders, the same crews and the same Mississauga showroom. That is where the basement portfolio, the layouts and the square-footage pricing live, and it is the better place to start a basement enquiry.
The boring, important part
Ask us for any of it in writing before you sign anything — with us or with anyone else.
The showroom is in Mississauga and the cabinets are built in Woodbridge, but the crews work well past the GTA — Collingwood and Barrie to the north, out to Peterborough and Cobourg in the east, Kitchener and Brantford to the west, and down through Hamilton to Niagara.
Further out across the GTA depending on the size of the project — put your postal code in and we’ll tell you.
