Fire & Water - Cleanup & Restoration

Empty properties are a breeding ground for mold.

Vacant homes can be breeding grounds for mold growth. Quite often we are called to a vacant home that is up for sale or the renter has moved out. The realtor/rental agent has come to show the home and finds mold growing on the walls. Mold can be seen growing most often in the upper wall locations, though it is not unusual to see growth at the lower wall levels as well. Closets that have been closed will quite often have the worst mold growth, partly because they are dark and mold loves the dark.

What could cause this? No broken water lines are found, the water is usually turned off to the home. Sometimes the HVAC system is off and that is the source of the problem. Having the heating and air turned off creates a high humidity level in the home. When the HVAC system is off there is no airflow circulating in the home therefore the air becomes stagnant. This is the perfect scenario for mold development.

Here are some tips on preventing mold issues in vacant homes:

  • Always keep some heat and air running in the home. Set temperature so heat or air runs periodically during the day.
  • Open closet doors to allow for airflow and light to enter.
  • A ceiling fan left on low can help circulate the air in the home.
  • Open window treatments/blinds at least ¼ open to allow in extra light. Remember, mold loves the dark.
  • Visit the home occasionally. Just opening the doors and entering the structure allows for the exchange of fresh air and extra airflow. It’s also a great way to catch any issues before they become serious problems
