Finishing a basement in Grimsby
Permits

Finishing a basement with new walls, a bathroom or a bedroom needs a Town of Grimsby building permit. We prepare the drawings, apply and book each inspection.

Second units

Ontario now allows additional units in most houses on full municipal services. A basement apartment still has to meet the Building Code as a separate home, and we confirm what your lot allows first.

Sump pumps

If there is a sump pit, it stays reachable behind an access panel. We can put the pump on its own circuit and suggest a backup before floors go in.

Older Grimsby homes

Some older homes near Grimsby Beach have low basements or crawlspaces. We measure headroom and check for damp before suggesting what the space can become.

Questions

Grimsby basement renovation FAQ

Do you finish basements in Grimsby?

Yes. We finished the Mountainview basement in Grimsby and work across Grimsby, Grimsby Beach, Beamsville, Lincoln and Stoney Creek from our Burlington office.

How much does it cost to finish a basement in Grimsby?

It depends on size and what goes in. The table above shows our ranges for a family room, a room with a bedroom, and a basement apartment, all before HST.

Do you charge extra to travel to Grimsby?

No. Grimsby is priced the same as Burlington, travel included.

Do I need a permit?

Yes, for new walls, a bathroom or a bedroom. It comes from the Town of Grimsby, and we handle the drawings, application and inspections.

Can I put a bedroom in my basement?

Yes, if it has a window large enough to get out through. If the existing window is too small, we can enlarge it.

Can I add a basement apartment?

Ontario now allows additional units in most houses on municipal services. It needs a separate entrance, fire separation, connected alarms and a permit. We confirm your lot first.

How long will my basement take?

Usually a month to six weeks of work in the house, once the layout is set and the Town has issued the permit.

What if something goes wrong after you finish?

Call us and we come back. Our workmanship is covered for four years, and flooring, fixtures and windows carry their makers' warranties.
