Our mission is to provide a full service qualitative approach to indoor air quality and microbial concerns by coordinating the investigation, remedial design and application elements of each project. We are committed to achieve leadership and excellence in providing high quality microbial assessment, investigation and certified mold remediation services throughout NJ, PA, & DE. We believe this can be accomplished by recognizing and meeting our essential responsibilities to our clients, employees, suppliers, and the community. Our approach allows us to provide our clients cleaner and healthier living by utilizing practical experience, technical excellence, and client responsiveness.

"I needed to have a mold issue addressed in my condo which had developed due to a leak in the roof. I contacted Aerotek Environmental having received their contact details from Angi Ads. From my first contact with Brandon of Aerotek Environmental he was the most helpful of all that I had spoken to about my issue. In addition to giving a reasonable cost estimate, Brandon took the time to carefully explain the step by step remediation process that his company would provide which included digital photos before, during and on completion of work. Having decided to use Aerotech the process ran very smoothly from setting the schedule date through the actual work and payment for services. Communication with Brandon was excellent - If I called or sent a text Brandon would either promptly answer or respond in a very short time. On the scheduled day, Felix Castro (job foreman) and his team arrived on time. Felix explained in detail exactly what he and his team would be doing. On completion of the work, Felix ensured that all debris was removed and provided full details as to what had been done and what he and his team found to be the most likely area of the leak. I am very satisfied with the entire process of working with Brandon who along with Felix and his team provided excellent customer service and would not hesitate to call in again should the need arise. I would highly recommend Brian and Aerotek Environmental to anyone in need of mold remediation services"

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."

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."

Mold Testing and Remediation questions, answered by experts

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Mold remediation is required if the mold growth covers more than 10 square feet of an area or the mold spore concentration is above 500 spores per cubic meter of air. You should also seriously consider remediation if there is a lot of water damage along with mold growth or if you suspect your HVAC system has been contaminated with mold. Remediation is also crucial if the mold damage has been caused by sewage or other contaminated water.

Condensation in your dryer can create a dangerous situation. It can cause lint to clog up the venting components of the system. If you have a gas-powered dryer, excessive lint buildup can create the potential for carbon dioxide buildup within your home. Clogged vent systems can also be a severe fire hazard. 

While mold in the bathroom can appear black, it isn’t always the dangerous black mold strain Stachybotrys chartarum. This type of mold typically appears after a flood or a long-term leak. If you suspect black mold, you should get it tested by a local mold testing service to determine whether it’s safe to remove yourself.

It’s unlikely your leaves are a hazard, especially if you get to them while they’re dry. However, a couple of rare risks exist. University studies suggest that decaying leaves can produce organochlorines, toxic pollutants similar to man-made PCBs (polychlorinated biphenyls), so avoid keeping them in an enclosed area.

Also, leaves and compost may cause the growth of fungi that can cause diseases like histoplasmosis and aspergillosis, as well as mold spores that are unhealthy for human lungs. Again, severe issues are rare, but those with compromised immune systems or allergies to mold should wear face masks when directly handling leaves.
