Answers to common questions about asbestos, mold, lead, and environmental testing.
If asbestos isn't being disturbed, there is little health risk. However, if asbestos-containing materials are in bad condition or are going to be renovated, there is a risk of asbestos fibers releasing into the air. Asbestos exposure can result in mesothelioma, asbestosis, and lung cancer.
The only way to be sure a material is asbestos containing is to have it analyzed by a qualified asbestos laboratory.
Asbestos containing materials were most commonly used pre-1978. However, imported materials may still contain asbestos. We recommend testing a building of any age before renovation or demolition.
Mold problems often present with visible mold growth. However, it is possible to have elevated levels of mold without visible mold. If you suspect a mold problem, we recommend a mold investigation be performed.
Mold will grow in moist areas. Oftentimes mold growth will occur indoors due to water leaks, high humidity, or condensation.
Mold will not go away on its own. The mold growth may die if the water source is removed, but the staining will remain.
Yes. To collect a mold sample, press a clear piece of tape against the discoloration. Be sure the discoloration shows on the tape and affix the tape to something clear (a plastic container, a second piece of tape).
Elevated blood levels can lead to kidney damage, nervous system damage, seizures, and death. According to the CDC, adverse effects have no threshold. Blood levels are considered elevated at or above 3.5 µg/dl for children and 5 µg/dl for adults.
If anyone in the household has an elevated blood level, prior to renovation in a pre-1979 home, or when there is damaged, flaking, or peeling paint in a pre-1979 home.
Collecting a lead sample yourself can be done for certain materials, such as paint chips or dust, as a preliminary step. However, proper sampling techniques are crucial. We recommend that samples be collected by a trained professional.
