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."

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."

"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"

Mold Testing and Remediation questions, answered by experts

The flooring that is the least toxic is solid wood. Natural linoleum, tile, stone, bamboo, and cork flooring also make the list of least-toxic flooring types. These flooring materials are safer and healthier for your home because they are natural materials that aren’t manufactured with chemicals, unlike laminate flooring. While some laminate flooring brands are made with less formaldehyde, many contain high levels of toxic chemicals that can off-gas in your home for months and years after installation.

Choosing natural flooring materials that are easy to clean without chemical cleansers can also help keep your home safer.

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.

According to the EPA, mold grows within 24 to 48 hours if left untreated after a water leak. So unless you notice the leak and stop it right away, you only have a day or so before mold is a real concern. If you don’t notice the leak, it can take about three weeks for the mold spores to become visible. That means you’ve likely had an active mold infection for a few weeks by the time you notice discoloration.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Water damage doesn’t always cause mold and wood rot, but it can. Both mold and wood rot require moisture in the wood to form, so water damage that continues to leave water or moisture behind can lead to both issues. Water damage and mold often go hand-in-hand, but you can prevent mold growth after water damage by addressing the source of moisture and drying out the area quickly. The same goes for wood rot. The longer you let water damage go, the higher the risk of mold and rot.
