Steam cleaning can prevent mildew from returning for a short period.

  • On dry days open doors or windows to allow fresh dry air to circulate your home to help remove any humid air.
  • Mold is commonly formed from leaks, so check windows regularly to see if they’re letting any rain seep in. Also, check guttering and drainpipes for the same concept.
  • Use any built-in extractor fans around your home to help remove humid air where windows can’t.
