Moisture or condensation on walls is usually a result of improper ventilation. Please always use ventilation fans and heat lamps that are provided with the property. If the home or unit does not have ventilation devices, you must crack a window or use your own if you do not want to crack a window. DO NOT PUT PLASTIC OVER YOUR WINDOWS IN THE WINTER. If the provided ventilation equipment stops working, please notify your manager. In some areas of a home, it may be necessary to regularly wipe down or clean shower surrounds and bathroom walls, cooking areas, and window seals.
