Mold likes damp, humid places.  Using a dehumidifier in damp areas of a home will help stop mold growth and keep it from coming back.  In bathrooms that do not have a vent, cracking a window or door will work in the same fashion.  You may need to fix leaky window seals, or other possible sources of leaks if mold continues to return.

Using a dehumidifier and keeping damp areas dry will help stop mold growth and help keep it from coming back.  Make sure that you properly clean affected mold areas.   Use a towel to keep walls dry after using the shower.  If mold returns quickly or spreads there may be an underlying problem such as a water leak.  

Make sure you are using the correct cleaning methods.  If the mold returns quickly or spreads, there may be an underlying water leak.  The best way to keep mold from coming back is to fix leaks and keep damp areas dry, such as using a towel to dry off walls or a dehumidifier.  Locate and repair any water leaks and accumulations found in your home.  

Property owners have an obligation to keep a rented residence in good condition so mold will not grow and present a safe living condition.  That means repairing water leaks and significant moisture accumulation.  If you have a significant amount of mold or it keeps coming back after you have cleaned it, it could be an indication of a larger issue such as a water leak or moisture accumulation.

If you find mold in a rented residence, take the proper steps to clean and prevent future mold exposure.  Follow the appropriate cleaning guidelines, and continue to maintain the affected area by keeping it dry and monitor for leaks.  If the mold returns quickly or spreads, contact the property owner to inform them of the mold and a possible leak.  If further assistance is required, contact your local code enforcement agency.

Make sure mold is cleaned properly.  Surfaces should be dry and clean before being painted.  If the mold returns quickly or spreads, there may be an underlying water leak or water accumulation.  It is the property owner’s responsibility to fix and maintain leaks to prevent mold.  Contact your local code compliance office if there is water accumulation or leaks which have not been addressed.   If a leak has been ruled out, maintain damp areas by keeping them clean and dry.
