Denver Mold Considerations

Low Humidity Advantage

Denver's dry climate (average 30-40% humidity) naturally inhibits mold growth compared to humid regions.

Basement Risk

Basements remain a concern due to groundwater and foundation seepage, especially during spring snowmelt.

Swamp Cooler Issues

Evaporative coolers can create moisture problems if not properly maintained or if used in enclosed spaces.

Winter Condensation

Cold winters can cause condensation on windows and walls, creating mold-friendly conditions.

New Construction

Tightly sealed new homes may trap moisture. Ensure proper ventilation in energy-efficient homes.

Mold Prevention Tips

Keep indoor humidity below 50% (use dehumidifier if needed)
Fix water leaks within 24-48 hours
Ensure proper bathroom and kitchen ventilation
Use exhaust fans when cooking and showering
Clean and maintain HVAC systems regularly
Insulate cold surfaces to prevent condensation
Improve air circulation in closets and corners
Clean gutters and ensure proper drainage away from foundation
Don't carpet bathrooms or basements
Monitor basement humidity especially in spring
