  • Real-time testing—state of the art technology can detect benzene, formaldehyde, methane, and PCBs immediately. You get real-time feedback.
  • A comprehensive report, written so you can understand it, documenting our real-time test results, laboratory findings (for any specimens sent to our lab), and interpretation of those findings.
  • We’re a company insured so you can rest assured.
  • Credit cards are accepted.

Real-Time Testing

In many instances, we can perform a real-time test. This means that while the inspector is there, he can immediately inform the owner if there are elevated readings of the substance–or not. For airborne toxins, we utilize portable gas-chromatography-based detectors for real-time measurements with unsurpassed accuracy and extremely low detection limits (ppb = parts per billion):
benzene: 5 ppb;
ethylbenzene: 10 ppb;
formaldehyde: 100 ppb;
methane: 0 – 100% LEL (Lower Explosive Limit) and 0 – 100% by volume of sampled air;
toluene: 3 ppb;
xylene (m-xylene): 10 ppb.

Protocols and Documentation

Our trained, certified, experienced, and professional inspectors will conduct our investigation while adhering to protocols approved by a Certified Industrial Hygienist. After our inspection is complete, we will prepare and send to the owner our comprehensive and comprehendible report, documenting our real-time test results, laboratory findings (for any specimens sent to our lab), and interpretation of those findings. It also includes detailed recommendations on how to reduce your exposure to toxic substances in your immediate environment.

Mold Testing

Concerning mold and mycotoxins–certain molds, such as Stachybotrys, and some kinds of Penicillium, are known to produce airborne toxins called mycotoxins.  One Stachybotrys chemotype can produce trichothecene mycotoxins (including satratoxins), and another can produce atranones. (See additional reference below.) What those toxins cause in us can vary from person to person.  If a person is very susceptible to mold then any kind of mold in any quantity may affect that person.  All mold indoors is bad but not all mold is toxic–matter of fact, most molds are not toxic. But, our laboratory analysis of submitted samples (from both indoors and outdoors) will identify the type and quantity of mold spores present in the samples, and reveal whether indoor spore counts are elevated.

Formaldehyde Testing

We can check your formaldehyde levels (also BTEX and Methane) in real time. Exposure to formaldehyde can cause symptoms like watery eyes, burning sensations in the eyes, nose and throat, nausea, coughing, chest tightness, wheezing, skin rashes, and allergic reactions, or it can cause no discernible symptom at all, though it is a known carcinogen. Don’t suffer from exposure, or concern that you are being exposed. You can schedule an inspection right away.
