Basement Renovation in Burlington

A finished basement adds a full floor of living space without changing the outside of the house. Done properly, it starts with keeping the space dry and warm. In Burlington, south Burlington has mid-century homes on mature lots, and the north has subdivisions from the 1980s onward.

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.
