ATLAS Environmental Inspections is a fully licensed and fully insured environmental inspection firm offering experienced and professional mold and asbestos testing services to residential, commercial, and industrial clients in the greater Philadelphia, Chester, Montgomery, Bucks, and Delaware counties. ATLAS Environmental Inspections continually strives to provide professional, courteous, and accurate environmental inspection services with an emphasis on total customer satisfaction. Atlas Environmental Inspections believes in partnering with its clients and attempts to simplify highly technical industrial or chemical jargon into a more understandable context. Most of our clients have never been exposed to an environmental hazard and consequently do not know where to turn for testing or what steps to take in addressing these concerns.

"I had a bad experience with a different company, and so, I was a little skeptical and wary when I started working with Jason. He was very patient with me, showed me all his credentials, took the time to explain what he would be doing and why, and otherwise showed me that he runs a competent and professional outfit. The type of test they took satisfied my insurance company and they even offered to let me pay after the test was done. In short, I am 100% satisfied with Jason and Atlas Environmental Inspections. It was great being able to work with such a great company after having had that previous bad experience."

"We had our radon fan replaced by Radon Bros in January 2025. From the beginning, the new fan was noticeably louder than the previous one. At that time, the technician advised us that the increased noise was due to the fan being stronger than our prior unit. Over time, the fan became increasingly louder and ultimately stopped working in early December 2025. When a technician returned to replace the fan, we were informed that the fan originally installed was defective and that Radon Bros had stopped using that manufacturer due to known issues. Despite this, we were charged a $99 labor fee for the replacement. We do not understand why we were responsible for this charge when the failure was due to a defective fan that your company was already aware of and no longer installs. We felt we had no choice but to pay the $99 in order to have our radon mitigation system restored and functioning properly. "

When you have mold, making the correct decisions right away is critical. Whether it is mold in your home, school, place of work, or apartment there are many factors to consider. Are you going to be involved in a mold lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need post mold remediation testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.

"The mold testing is fine. The mold remediation company is very sketchy. Just buy some air purifiers."

Mold Testing and Remediation questions, answered by experts

Refrigerant leaks are extremely toxic and dangerous to your health. Not only can you face health risks, such as headaches, nausea, and dizziness, but there’s also the chance of death or loss of consciousness. In addition, refrigerant leaks are toxic to the environment, and they can cause permanent damage to the ozone layer and the earth’s atmosphere.

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.

Mold thrives in wet or moist conditions, so a fridge water dispenser can be the perfect place for them to live. You may transfer mold to the dispenser's nozzle by touching it with the rim of an unwashed water bottle or your hands. 

If you see splotches that look like mold, you can clean them using vinegar. Distilled white vinegar is acidic enough to kill and remove most mold species.

Yes, mold under silicone caulk can potentially cause health issues, which may be more noticeable in people with asthma, allergies, or other respiratory conditions. Mold releases spores into the air, and inhaling these spores can cause symptoms such as coughing, sneezing, eye irritation, and skin rashes. It's important to address mold issues promptly to protect your health.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.
