Quick Answer

To prevent mold and mildew in a summer home, clean thoroughly before closing, remove all food and damp items, lower the thermostat and humidity, leave interior doors open for airflow, use moisture absorbers, and arrange for periodic checks. When reopening, ventilate immediately and schedule a deep cleaning to remove any early growth. On Martha’s Vineyard, where coastal humidity makes closed homes vulnerable, these steps protect the property. ICP Cleaning Services provides seasonal opening and closing cleaning across the island.

Closed summer homes are prime targets for mold and mildew. Prevention starts before you leave and continues at opening.

Why Closed Summer Homes Grow Mold

Mold and mildew need moisture, warmth, and still air to grow. When a summer home is closed for months with no ventilation, humidity builds up and creates the perfect environment — especially on Martha’s Vineyard, where coastal air is naturally damp.

Prevention is far easier than remediation. A few steps before closing and a proper opening clean keep the property fresh and protect finishes, fabrics, and air quality.

Before You Leave: Prevention Steps

  • Clean the home thoroughly and remove all food, trash, and damp items
  • Empty and clean the refrigerator, and leave the door propped open
  • Run the dishwasher and washing machine empty, leave doors open
  • Lower the thermostat and set dehumidifiers if available
  • Leave interior doors and cabinet doors open for airflow
  • Place moisture absorbers (DampRid or similar) in bathrooms and closets
  • Close windows tightly and check weather seals
  • Turn off water supply to prevent leaks during vacancy
  • Arrange for a caretaker or service to check the property periodically

At Opening: What to Check and Clean

  • Ventilate the home immediately by opening windows and running fans
  • Check for visible mold on walls, ceilings, grout, and fabrics
  • Sniff for musty odors that indicate hidden growth
  • Run dehumidifiers to pull out trapped moisture
  • Clean bathrooms, kitchen, and surfaces where mildew may have started
  • Wash any linens or fabrics that smell damp
  • Replace moisture absorbers

If you find visible mold, persistent musty odors, or months of dust and humidity residue at opening, a deep cleaning addresses the problem before it worsens. For extensive growth behind walls or in HVAC systems, a specialized mold remediation provider is needed.
