Before you start

What to know.

Permits
In most GTA municipalities, finishing a basement needs a building permit when the work involves structural changes, new plumbing, heating changes or a new entrance. We confirm what applies to your address.
Water first
Any leak, damp wall or drainage problem has to be fixed before framing goes up. Finishing over moisture leads to mould behind the walls.
Ceiling height
Low ceilings, ducts and beams limit what a basement can become. If more height is needed, underpinning can lower the floor.
