The Dangers of Hidden Moisture & Mold in Winter: Checking Attics, Crawlspaces, and Basements for Moisture

2/5/2025 (Permalink)

Winter in Olathe, KS, and surrounding cities, brings cold temperatures, snow, and ice—but it can also create the perfect conditions for hidden moisture and mold growth in your home. While you may not see standing water, damp areas in attics, crawlspaces, and basements can lead to mold infestations, structural damage, and even health concerns. Here’s what you need to know about detecting and preventing moisture buildup in your home this winter.

Why Moisture Buildup Happens in Winter

Cold weather and increased indoor heating can lead to condensation in hidden areas of your home. Factors contributing to moisture issues include:

• Poor ventilation – Trapped warm air in attics and crawlspaces can create condensation.

• Ice dams – Ice buildup on roofs can force water under shingles and into attics.

• Frozen pipes – Burst pipes can leak water into basements and crawlspaces.

• Snowmelt seepage – Melting snow can enter through foundation cracks or poor drainage.

Where to Check for Hidden Moisture

Attics:

• Look for dark stains on wood or insulation, which indicate water intrusion.

• Check for frost buildup on roofing nails or rafters, a sign of poor ventilation.

• Ensure attic vents are not blocked by insulation or debris.

Crawlspaces:

• Inspect for damp or musty odors, which can signal hidden mold.

• Feel the ground and foundation walls for excess moisture.

• Check for standing water, which may indicate a drainage problem.

Basements:

• Look for water stains on walls or floors, especially near foundation cracks.

• Monitor humidity levels—high humidity can accelerate mold growth.

• Inspect sump pumps and drains to ensure they are working properly.

How to Prevent Moisture & Mold Growth

• Improve ventilation by using exhaust fans and keeping vents unblocked.

• Use dehumidifiers in damp areas to control humidity levels.

• Inspect and clean gutters to prevent ice dams and roof leaks.

• Seal foundation cracks to keep melting snow from seeping in.

• Schedule a professional moisture inspection, with your friends at SERVPRO- if you suspect hidden water damage.
