A quick note from the editor:
Before you turn a lower level into a room people will actually use, test what you cannot see and document what the basement is already telling you.
🧭 What should I do next?
Should I care?
Once finishes go in, bad basement air gets more expensive to understand and harder to correct. Radon, humidity, mould clues, and stale-air patterns are worth catching before the room starts looking "done."
Who is affected?
Homes with basements used for offices, guest rooms, playrooms, storage, or future rental space, especially older Montreal homes with stone foundations or mixed moisture history.
What's next?
Start a long-term radon test before making any finishing decision for the basement.
