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."

Mold Testing and Remediation questions, answered by experts

The primary signs of mold in an ice machine is a musty odor, slime buildup, and discolored ice. If you notice any of these signs, clean your ice maker immediately.

If you would like the insurance company to potentially help you pay for the mold remediation, you need to inform the insurer. When you notify your insurance company, they may say that you need a mold inspection before receiving any money for mold remediation. It’s possible that the insurer would not pay for this inspection unless they find mold.

Black mold and wood rot are both types of fungi that form in damp or wet areas, but they cause different problems. Black mold grows on the surface of wood or other materials, while wood rot affects the structure of the wood material. Additionally, inhaling or contacting toxic black mold spores can make people sick. Wood rot spores are not known to cause illness in humans. 

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.

Cork floors are naturally antimicrobial, which helps increase their resistance to mold and mildew growth. But mold and mildew can still grow on cork floors if you install them in a humid room or if they are exposed to moisture, like a spilled glass of water that you don’t clean up quickly. It’s important to keep cork out of high-moisture areas like bathrooms and clean up spills as soon as they happen to avoid mold growth.
