Why Indoor Moisture is a Problem in Winter
Wisconsin winters bring cold temperatures, but they also introduce indoor moisture issues that can lead to mold growth, condensation, and property damage. Controlling indoor humidity is key to keeping your home safe and comfortable.
As temperatures drop, homes are sealed tightly to keep heat in. This traps moisture from cooking, showering, and daily activities, increasing humidity levels. Signs of excess moisture include:
✔️ Condensation on windows
✔️ Musty odors in basements or bathrooms
✔️ Peeling paint or warped wood
✔️ Visible mold growth on walls or ceilings
5 Tips to Reduce Moisture & Prevent Mold
✅ 
Use Exhaust Fans Properly
Run bathroom and kitchen exhaust fans while showering or cooking. Keep them on for at least 
20–30 minutes afterward to fully vent moisture.
✅ 
Control Humidity Levels
Keep indoor humidity between 
30–50% using a 
hygrometer. If levels are too high, use a 
dehumidifier, especially in damp areas like basements.
✅ 
Check for Condensation on Windows
Wipe away moisture and improve air circulation by 
keeping blinds and curtains open during the day. Persistent condensation may indicate ventilation issues.
✅ 
Prevent Water Leaks
Inspect 
plumbing, roofs, and basements for leaks. Even small drips can cause 
hidden mold growth behind walls. Address water damage immediately.
✅ 
Improve Airflow
Move furniture 
away from walls, run 
ceiling fans on low, and open interior doors to 
improve ventilation and reduce moisture buildup.
