Poor air circulation, high humidity undetected leaks and unclean air filters can all contribute to elevated mold conditions in your home.  In most cases, there is no visible mold in the home, however, this does not mean that you are in the clear.  Several clients have called me this year explaining that there allergic syptoms that had been progressing over several months.  Some were advised by their Doctors to get tested for mold allergies.  Through air testing, we were able to determine that several of the homes had very high mold conditions causing family members to become very sick.  Professional remediation was necessary in many of these cases.
