Mold Investigation and Mold Testing

If you’ve found something that looks like it could be mold in your home or building, ESG can perform mold testing to determine what it is.

Mold is commonplace and the spores are usually harmless in small amounts, but when the spores come into contact with moisture (for example, from a leak, a flood, or excess humidity) they can grow. When this happens, spores are released into the air, where they can be inhaled by the building inhabitants. Depending on the type of mold it is and the susceptibility of the individuals exposed, this can be a health risk.

There are many kinds of mold, and some kinds are more dangerous than others. Toxigenic molds are especially dangerous and should be dealt with immediately. When people say “black mold,” they’re usually referring to toxigenic mold, but not all black mold is toxigenic, and not all toxigenic mold is black. 

What Does Mold Testing Entail?

An investigator (who is a certified Indoor Environmental Professional) will  take air and/or surface samples from the space and hand-deliver them to an independent, accredited lab for analysis. The investigator will then provide a report of the assessment that includes the data collected, the lab test results, and recommendations for improving your air quality. 

Symptoms of Mold Allergy/Exposure

The most common symptoms of mold exposure are respiratory reactions, including runny nose, sinus congestion, sneezing, coughing, itchy eyes, sore throat, and wheezing. Headaches are also a common occurrence, and asthma attacks are often triggered by mold in those who have asthma.

Some of the less common symptoms include digestive issues, skin rash, joint pain, fatigue, and mental symptoms like depression and memory loss.
