"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

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"

Radon Detection and Reduction questions, answered by experts

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.
