Mold Prevention Tips for Vacation Homes and Seasonal Properties

Owning a vacation home or seasonal property in Massachusetts is a dream—but it comes with unique responsibilities. When a home sits unoccupied for weeks or months, it's more vulnerable to moisture buildup and mold growth. Without proper precautions, mold can silently spread behind walls, in basements, or inside HVAC systems—leading to costly cleanup and damage when you return.

Whether your second home is in the mountains, by the coast, or tucked into a quiet New England neighborhood, here are practical mold prevention tips to help keep it safe year-round.

Why Vacation Homes Are at Higher Risk for Mold

Mold thrives in areas with:

• High humidity

• Little to no ventilation

• Undetected leaks or moisture intrusion

Seasonal homes are often closed up for long periods, with HVAC systems turned off, water lines idle, and no one present to catch small problems before they become big ones.

Top Mold Prevention Tips for Seasonal Properties

1. Shut Off and Drain Water Lines (If Vacant During Winter)Turning off the main water supply and draining pipes can prevent burst pipes and leaks during freezing weather. Leaks that go unnoticed for months are one of the top causes of mold damage in second homes.

2. Maintain Proper VentilationStagnant air and high humidity are a recipe for mold. Use a programmable thermostat to run your HVAC system periodically, or install a ventilation system with humidity control features.

3. Use a Dehumidifier with DrainagePlace a dehumidifier (ideally one with a continuous drain to a sump or floor drain) in moisture-prone areas like basements or crawl spaces. Keeping humidity below 50% is key to mold prevention.

4. Inspect and Seal the Roof and WindowsBefore closing up for the season, inspect the roof, flashing, and window seals. Even minor gaps can let in water during storms or snow melt.

5. Clean and Disinfect Before LeavingWipe down surfaces, clean out the fridge and pantry, and empty garbage. Mold can grow on food residue, damp rags, and even dust when left undisturbed.

6. Keep Interior Doors OpenThis promotes air circulation and reduces the risk of mold growing in closets, bathrooms, or other closed-off rooms.

7. Install a Smart Water Leak DetectorConsider installing smart leak detectors that alert you via smartphone if water is detected. Some systems can even automatically shut off your water.

8. Schedule Routine Property ChecksIf possible, have a trusted neighbor, property manager, or home watch service check in periodically—especially after heavy rain or freezing temperatures.

Bonus Tip: Get a Mold Inspection Before Peak Season

Before opening your home for the season, schedule a mold inspection to ensure everything is safe and clean. Mold can develop slowly over time, especially in basements, attics, and behind walls where you can’t see it.
