Mold Remediation Mold vs Mildew mold

There are 3 Basic Categories of Water

Category 1 originates from a sanitary source and poses no substantial risk from dermal, ingestion, or inhalation exposure. However, it may not always remain clean after it comes into contact with other surfaces or materials.

Category 2 contains significant contamination and has the potential to cause discomfort or sickness if contacted or consumed by humans. It may contain potentially unsafe levels of microorganisms or nutrients for microorganisms, as well as other organic or inorganic matter (chemical or biological).

Category 3 is grossly contaminated and may contain pathogenic, toxigenic or other harmful agents. Such water sources may carry silt, organic matter, pesticides, heavy metals, regulated materials, or toxic organic substances.

The 4 Primary Classifications of Water Damage

Class 1 is the least amount of water, absorption and evaporation.  It affects only part of a room or area, or larger areas containing materials that have absorbed minimal moisture.  Little or no wet carpet and/or cushion is present.

Class 2 involves a large amount of water, absorption and evaporation.  It affects at least an entire room of carpet and cushion (pad).  Water has wicked up walls less than 24 inches.  There is moisture remaining in structural materials and substructure soil.

Class 3 involves the greatest amount of water, absorption and evaporation.  Water may have come from overhead.  Ceilings, walls, insulation, carpet, cushion and subfloor in virtually all of the entire area are saturated.

Class 4 relates to specialty drying situations.  Wet materials with very low permeance/porosity (eg. hardwood, plaster, brick, concrete, light-weight concrete and stone).  Typically, there are deep pockets of saturation, which require very low specific humidity.  These types of losses may require longer drying times and special methods.

Mold in my basement

11/23/2018 (Permalink)

Several times a week during this humid rainy summer we get called to inspect a basement with apparent mold growth primarily on furniture, clothing, and some of the drywall or paneling. With no apparent water damage, homeowners are stumped as to why they have mold. Here are some common factors in these outbreaks:

  1. Homeowners don’t go down to the basement much anymore.
  2. Humidity control by dehumidifier or central air conditioning is absent.
  3. If air conditioning is available, many times the vents are closed.
  4. Very little direct light and little or no air-flow.

 So if you have a basement that does have air conditioning, make sure you leave the vents open during the summer heat and humidity – even if you don’t use the space often.

If you don’t have AC, put dehumidifiers in the space and use the manufacturer’s recommendations as to how much space the unit will handle. You may need more than one. Also, it’s a good idea to keep a fan running to circulate the air.
