RE: 436 Sunnybrook
The mold that was on the backside of the floor sheeting & I joist was removed with a solution on
1.5 cups of bleach to a gallon of water. This was applied & then air-dried. This was the
recommended way to remove from Western Wood Products Association and the National
Association of Rome Builders.

r"'lolds can be found almost anywhere; they can grow on virtually any substance,
providing moisture is present. There are more than 100,000 species of mold and at
least 1,000 varieties are common in the U.S., according to the New York City
Department of Health. Mold is most likely to grow where there is water or dampness,
such as in bathrooms and basements.
Mold can occur naturally on lumber under certain conditions, normally due to the
presence of moisture in or on the wood and warm temperatures. Molds are fungi,
ubiquitous organisms that under proper conditions can grow on organic matter. Surface
molds, which can come from a variety of sources including airborne spores, feed off the
sugars and starches readily available in wood.
Cleaning Mold
WWPA has reviewed recommendations from a variety of sources on cleaning and
removing mold from wood. The most common recommendation is to clean the wood
with a mixture of bleach or soap and water, as shown in the following:

"For exposed conditions, any discolored wood can be cleaned by using a mixture of one
part household bleach to three parts water sprayed on the wood or applied with a
non-metal brush. The wood should be flushed clean afterwards. Commercial mildew
removers are also available."

"Small areas of mold should be cleaned using a detergent/soapy solution or an
appropriate household cleaner. Gloves should be worn during cleaning. The cleaned area
should then be thoroughly dried. Dispose of any sponges or rags used to clean mold."

Health Effects Associated With Molds
Generally, the majority ()fcommon molds are not a concern to healthy individuals.
Currently, the Environmental Protection Agency does not regulate mold or mold spores
in indoor air. Some forms of mold, however, may pose potential'health risks under
certain conditions.
According to the Center for Disease Control (CDC): "There are very few case reports
that toxic molds (those containing certain mycotoxins) inside homes can cause unique
or rare, health conditions such as pulmonary hemorrhage or memory loss. These case
reports are rare, and a causal link between the presence of the toxic mold and these
conditions has not been proven."

molds:
