Mold in Calgary usually starts with moisture, not âdirtyâ homes. In our climate, the big culprits are leaks, condensation, and poor ventilation around cold surfaces.
Common building-related causes in Calgary:
- Roof, window, or foundation leaks that let in meltwater, rain, or groundwater, especially during Chinooks and spring thaw.
- Condensation on cold walls, basements, and windows when warm indoor air hits cold surfaces in winter.
- Poor ventilation in bathrooms, basements, attics, mechanical rooms, and cold rooms, so everyday humidity from showers and laundry has nowhere to go.
- Tightly sealed, energyâefficient buildings that trap moisture inside wall cavities and around insulation when thereâs even a small leak.
If you are already seeing musty smells, staining, or fuzzy spots, that means the problem has started. Wise Abatement can safely remove the mold and contaminated materials so your contractor can fix the moisture issue and put everything back together. Send us a message to book remediation!
