You won't always see mould, but your home and body may signal it in Brockville.
- A persistent musty smell
- Allergy symptoms that ease when you leave home
- Past water damage or leaks
- Warping or discoloured walls
- High indoor humidity
- Condensation on windows
- A damp basement or crawlspace
Any of these is worth a mould inspection.
Musty smell but no visible mould? That's exactly when inspection helps.
