HVAC Tips

Preventing Basement Moisture in Connecticut’s Older Coastal Homes

November in Southwest Connecticut often brings heavy rains, damp soil, and high humidity—conditions that can create basement moisture problems, especially in older coastal homes. Moist basements can lead to mold growth, structural issues, and musty odors, creating both comfort and health concerns.

With proactive steps and HVAC strategies, homeowners can keep basements dry, protect their homes, and maintain indoor air quality during the fall season.

Why Basements Are Vulnerable in Coastal Homes

1. Damp Soil and Rainwater

Coastal regions often have high water tables and saturated soil, which can seep into basement foundations during November storms.

2. Aging Foundations

Older homes may have cracks or gaps that allow moisture intrusion more easily than modern constructions.

3. Poor Ventilation

Limited airflow in basements allows humidity to build, creating ideal conditions for mold and mildew.

4. HVAC System Limitations

Older or improperly maintained systems may not remove excess moisture effectively, leading to dampness.

Steps to Prevent Basement Moisture

Use a Dehumidifier

A quality dehumidifier keeps humidity levels in check (30–50%), preventing mold growth and musty odors.

Maintain Your HVAC System

Ensure ducts, vents, and filters are clean and functioning properly to help regulate basement humidity.

Seal Cracks and Gaps

Inspect foundation walls, floors, and basement windows. Seal any openings to prevent water seepage.

Improve Airflow

Circulate air with fans or vents and consider opening vents to connect basement air with the main HVAC system.

Extra Tips for Coastal Homeowners

  • Check Gutters and Downspouts: Direct water away from the foundation to minimize moisture intrusion.
  • Elevate Stored Items: Keep boxes and furniture off the floor to avoid water damage.
  • Monitor During Storms: Inspect basements after heavy November rains for early signs of water intrusion.
