Severe toxic mold contamination beneath the floor board and on walls

The first thing to understand about mold is that there is a little mold everywhere - indoors and outdoors. It's in the air and can be found on plants, foods, dry leaves, and other organic materials.

It's very common to find molds in homes and buildings. After all, molds grow naturally indoors. Mold spores enter the home through doorways, windows, and heating and air conditioning systems. Spores also enter the home on animals, clothing, shoes, bags and people.

When mold spores drop where there is excessive moisture in your home, they will grow. Common problem sites include humidifiers, leaky roofs and pipes, overflowing sinks, bath tubs and plant pots, steam from cooking, wet clothes drying indoors, dryers exhausting indoors, or where there has been flooding.

The importance of mold in the real estate market today


Various Mold Types

Much has been made of indoor mold in advertising and the media lately, so it's a common concern for homeowners and buyers. It's common to find mold even in new homes. Whether you're selling your current home or looking into buying one, it's vital to get a mold inspection. Presence of active mold can drastically affect the resale value of any home.

For homeowners, a mold inspection will either put your mind at rest or make you aware of any problems that could otherwise cause delays or deal breakers once you've entered negotiations with a buyer. A professional mold inspection will give you a signed report from an expert before you put the home up for sale. Imagine being able to show a "clean bill of health" to potential buyers that express concerns - they'll be impressed by your thoroughness and commitment to your home.

For buyers, getting a mold inspection will ensure that you're not surprised by costly clean up and the potential health hazards of mold. If any mold is found to be present and active in the home, the mold inspection will allow you to ask the seller to do the clean up prior to buying the home.

Mold Testing and Assessments:

The first step in an assessment is to determine if mold is present. This is done by visually examining the premises. If mold is growing and visible this helps determine the level of remediation that is necessary. If mold is actively growing and is visibly confirmed, sampling for specific species of mold is unnecessary.

These methods, considered non-intrusive, only detect visible and odor-causing molds. Sometimes more intrusive methods are needed to assess the level of mold contamination. This would include moving furniture, lifting and/or removing carpets, checking behind wallpaper or paneling, checking in ventilation duct work, opening and exposing wall cavities, etc.

Careful detailed visual inspection and recognition of moldy odors should be used to find problems needing correction. Efforts should focus on areas where there are signs of liquid moisture or water vapor (humidity) or where moisture problems are suspected. The investigation goals should be to locate indoor mold growth to determine how to correct the moisture problem and remove contamination safely and effectively.

Three types of sampling are available:

  • Air sampling: the most common form of sampling to assess the level of mold. Sampling of the inside and outdoor air is conducted and the results to the level of mold spores inside the premises and outside are compared. Often, air sampling will provide positive identification of the existence of non-visible mold.
  • Surface samples: sampling the amount of mold spores deposited on indoor surfaces (tape, and dust samples)
  • Bulk samples: the removal of materials from the contaminated area to identify and determine the concentration of mold in the sample.

When sampling is conducted, all three types are recommended by the AIHA, as each sample method alone has specific limitations. For example, air samples will not provide proof of a hidden source of mold. Nor would a tape sample provide the level of contamination in the air.

Air sampling following mold remediation is usually the best way to ascertain efficacy of remediation.
