Everyone responds differently to mold. Some people are very sensitive, while others don’t respond to very high levels of mold.Higher levels of toxic mold spores has been linked to asthma in some groups. Most reactions are sneezing and coughing when exposed to higher levels of mold. Please consult your physician or health professional for personal guidance.

Your physician may want to run additional allergy tests before giving you guidance. Please show your physician your report. We are always available to answer questions.

The laws around asbestos sampling are complicated. Basically, we need 3 samples of each material identified on the EPA asbestos list that is under 5,000 square feet. More info here.

If your building was built before 1981, there is a high probability that asbestos is present. Test BEFORE you demo or remodel. Read more Assess Your Asbestos Risk.

Formaldehyde is used in building materials, primarily as an additive to wood glue because it requires a low-cure temperature and is resistant to abrasion.  Formaldehyde is a carcinogen.  Formaldehyde was listed by the State of California  in 1988 as a chemical that causes cancer. There is a new bill under current review that will ban formaldehyde in beauty products, especially baby shampoo. Formaldehyde off-gasses quickly to the point where it is not smelled by most, but the chemical still remains in the air.
