HVAC Tips

Managing Humidity and Mold in Older Delaware Homes

November’s cool, wet weather can make older homes in Newark more susceptible to humidity and mold. Basements, crawlspaces, and poorly insulated areas are particularly vulnerable. Excess moisture can cause damage to wood, walls, and flooring while also creating health risks for your family.

Fortunately, managing humidity and preventing mold is possible with the right HVAC strategies and home maintenance.

Why Older Homes Are More Vulnerable

1. Outdated Insulation and Sealing

Older homes often have gaps in walls, floors, or around windows, allowing cold, damp air to enter and trap moisture inside.

2. Limited Ventilation

Homes built decades ago may not have modern ventilation systems, making it harder for moist air to escape.

3. Basements and Crawlspaces

Lower levels often lack proper airflow, allowing humidity to accumulate and mold to grow.

4. Aging HVAC Systems

Older HVAC systems may struggle to remove excess moisture from indoor air, especially when running continuously in fall and winter.

How to Control Humidity and Prevent Mold

Use a Dehumidifier

Portable or whole-home dehumidifiers help maintain 30–50% indoor humidity, making it harder for mold to develop.

Inspect and Maintain HVAC Systems

Regular maintenance ensures proper airflow, clean filters, and efficient moisture removal.

Seal Air Leaks

Caulking windows, weatherstripping doors, and sealing gaps in floors and walls keeps damp air out and warm air in.

Improve Ventilation

Use exhaust fans in bathrooms and kitchens, and consider adding vents in basements or crawlspaces to circulate air effectively.

Monitor Humidity Levels

A hygrometer can help track moisture levels and alert you to areas that need attention.

Extra Tips for Newark Homeowners

  • Check for Water Intrusion: Look for leaks around windows, roofs, or foundations.
  • Keep Storage Off the Floor: Raise boxes and furniture to avoid contact with damp surfaces.
  • Address Mold Promptly: Small spots can be cleaned, but widespread growth requires professional help.
