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

You normally won’t see any dust or mold actively floating out of your vent, but you might notice your vent looks dirty. Mold will cling to the sides and collect almost like black soot. Dust will look, well, dusty, but there will usually be a heavy buildup so expect thick gray layers on the bottom and sometimes the sides of the vent. If you suspect you have mold in your vents, call a professional immediately.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Nearly all homes have at least some airborne mold spores. If you want to determine the concentration of spores in the air, you have a few options. The most effective option is to hire a professional tester who can take air samples of the home. The tester would send the samples to a laboratory to determine the concentration of mold spores. 

While the resistance of lime to mold is a hotly contested topic of debate, it is true that because it allows porous materials to breathe, it avoids trapping moisture close to the structure of a building. This breathability makes it less susceptible to mold than paint because it gathers less moisture.

If you’re wondering which is more toxic, laminate vs.vinyl flooring, you might be surprised to learn that both can include toxic chemicals. Depending on the specific brand and the manufacturing process, both are likely made from synthetic materials that can emit volatile organic compounds, or VOCs, into the air. However, since laminate has a wood core, it is more sustainable and less polluting than vinyl, which is entirely synthetic and almost always emits more VOCs than laminate flooring. If you’re concerned about indoor air quality, choose a low-chemical flooring manufacturer or, better yet, choose flooring that doesn’t off-gas VOCs.
