Exposure to mold

Everyone is exposed to some amount of mold on a daily basis, most without any apparent reaction. Generally mold spores can cause problems when they are present in large numbers and a person inhales large quantities of them. This occurs primarily when there is active mold growth.

For some people, a small exposure to mold spores can trigger an asthma attack or lead to other health problems. For others, symptoms may only occur when exposure levels are much higher.

Should I be concerned about mold in my home?

Yes. If indoor mold is extensive, those in your home can be exposed to very high and persistent airborne mold spores. It is possible to become sensitized to these mold spores and develop allergies or other health concerns, even if one is not normally sensitive to mold.

Left unchecked, mold growth can cause structural damage to your home as well as permanent damage to furnishings and carpet.

According to the Centers for Disease Control*, “It is not necessary, however, to determine what type of mold you may have. All molds should be treated the same with respect to potential health risks and removal.”

Can my home be tested for mold?

Yes. An indoor air sample can be taken as well as an outdoor sample to determine whether the number of spores inside your home is significantly higher. If the indoor level is higher, it could mean that mold is growing inside your home. Reliable air sampling can be expensive, time consuming, and requires special equipment and a qualified technician.

If you can see or smell mold, then you should take steps to clean-up the mold. Mold growth is likely to continue unless the source of moisture is removed and the contamination is cleaned-up.
