Signs to Watch For
- Damp soil, standing water or odours under your home.
- Damp or stained drywall, flooring or storage boxes
- Musty odour or noticeably higher humidity
- Problems that worsen after rain or spring melt
What Causes It
Most basement moisture comes from groundwater and surface water building up against the foundation, humid air meeting cool concrete, or drainage that can't keep up. In Calgary, clay soils that hold water and rapid freeze-thaw cycles make these issues common.
Why Not Wait?
Moisture rarely fixes itself. Left alone, it can damage finishes, stored belongings and indoor air quality — and repairs get more costly over time.
