Home Mold House Mold

A guide to common house mold locations

Home mold issues are a common concern among homeowners today.  Home mold problems are not new, but public awareness has increased dramatically over the last decade.  The affect of the increased awareness has lead to positive and negative repercussions.  Homes are now built with better moisture management techniques to reduce the incidence of home mold problems. Unfortunately the increased awareness also created numerous misconceptions and unfounded fears regarding mold growth

How common are home mold problems?

  • No reliable statistics exist for residential mold issues, however the EPA estimates as many as 30% of homes suffer from mold problems. 

What are the most common house mold problems?

  • The answer depends largely on the location of your home.  In the Southwest for example, with high outside temperatures and cool, air conditioned homes, mold growth inside the wall cavity is common.  In cooler climates like the Pacific Northwest, mold growth in a wall cavity is rare unless a water leak occurred.  More commonly, mold growth is found on the side of the sheetrock facing the inside of the home. 
  • Common areas of home mold problems include attics, crawlspace, bathrooms and walls with plumbing fixtures. 

Is it possible to keep your home mold free?

  • No, maintaining a 100% mold free environment in your home is impossible.  Mold spores are ubiquitous, every time you open a window or door, mold spores and fragments enter your home.  The only environments considered 100% mold free are clean rooms in hospitals with highly specialized filtration equipment. 
  • When considering the goal of keeping your house mold free, focus on maintaining an environment free of mold growth.  You cannot eliminate the mold spores from your home, however, you can prevent spores from colonizing and growing.
