  • Humidity Testing And Mold Problems In Hot Humid Climates
    In hot humid climates, such as are encountered in tropical and sub tropical regions around the world proper humidity testing and control can be crucial to properly understanding and solving a mold problem.

    In fact many coastal homes in Florida and the South East experience mold problems in the absence of any leaks. Many homeowners and even mold inspectors fail to properly understand the connection between common building defects that cause humidity and the buildings mold p...
  • Mold Inspection Tips For Homeowners
    I once received a call from a potential mold inspection client who feared that she may have hidden mold in her walls. She was concerned about possible hidden mold because a mold inspector told her that the ants observed in her property were a very likely sign of hidden "house mold" because ants eat mold.

    Forget about house ants

    Before we discuss a few basic tips on how to look for mold and moisture problems around the house lets talk about how not to find mold. Do not d...
  • Mold Testing Methods Surface Samples
    When a mold inspector takes bulk, tape, carpet/dust, or swab samples, spore numbers are not compared quantitatively to outdoor levels. Thus, the number of spores in these types of samples often are not as meaningful as the numbers found in air samples. Also, because the air is not being tested, your inspector cannot say for sure how much if any of the mold sampled from surfaces is in the air you are breathing. However, these samples can be helpful because they typically provi...
  • Mold Allergy And Other Mold Related Health Issues
    MOLD ALLERGY

    The leading cause of health problems associated with mold is the common mold allergy. Many who believe they are being poisoned by toxic molds are actually experiencing a mold allergy. Allergenic responses to molds as well as to other bio-allergens such as dust mite allergens, cat and dog allergens, and cock roach allergens can nevertheless be a serious concern and can result in mild to severe reactions that often get worse over time. Mold allergy symptoms incl...
  • The Most Popular Mold Testing Methods
    Below are the five most widely used methods of taking mold spore samples from the air during mold inspections. They are used by scientists, industrial hygienists, and mold inspectors.

    These mold testing methods have been proven over and over by time, legal trial, and third party scientific lab verification for reliability taking into account many complex factors related to aerodynamics and physics. Surface sample methods just do not provide as much quantitative info as the...
  • Do It Yourself Home Mold Testing Kits
    What are they good for?

    If you feel that you have a mold problem, you can save money on a mold inspection by buying a mold testing kit from your local South Florida building supply store. The kit consists of a standard, plastic Petri dish containing a mold growth media, most likely MEA (Malt Extract Agar.) Simply open the kit and let mold spores fall in it from the ambient air above it. Within a few days, mold colonies will start to grow. Typically, you will see black, whi...
  • Mold Spores In Your Home
    The below information was not provided as final and defenitive mold spore level specifications because health responses to mold spore exposures differ from person to person. Also, health responses to mold spores can be affected by the length of time you are exposed to spores, the size or type of spore you are exposed to, the levels of dust mite and roach allergens, individual sensitivity to allergens, emotional stress, general health, as well as other substances and factors t...
  • How To Identify Toxic Black Mold
    Stachybotrys not always, but almost always exhibits a circular growth pattern forming round colonies of about 1 inch or less to about 1 foot across approximately. Sometimes the circles are complete.

    Other times, the circles are incomplete and form semi circles or crescent moon shapes when one side of the colony grows but the other side does not grow well, possibly due to a lack of moisture or competition with other mold types on the weaker growing side of the colony. Also,...
  • Mold Biology And Mold Related Heath Issues
    BASIC MOLD BIOLOGY:

    Fungi share some basic similarities with plants and bacteria but are not plants nor are they bacteria. They are in their own kingdom, the Fungi Kingdom.

    The terms mold and mildew are often used interchangeably by lay persons, but according to some more specific definitions, mildew is a powdery growth that attacks and grows on living plants while molds are often fuzzy and grow on all sorts of moist surfaces. Molds, mildews, and other fungi usually rep...
  • 10 Common Indoor Air Quality Problems
    Mold and water damaged building materials

    When leakage occurs it results in the growth of mold that in turn results in the release of pungent smelling and irritating volatile organic compounds, and allergenic mold spores into your air. Persons with allergies or asthma often have reactions to such contaminates in the air while others may have no reaction at all. People with compromised immune systems may even contract infections from some molds.Fungal infections are more a ...
