"Henry came to our house. He was very knowledgeable about mold and what to look for. He answered all my questions and was very helpful. Peter who called me with the results was very nice and answered my questions. He even called back the next day when he noticed that an email he sent me didn t go through. They gave me a lot of information to help me continue my search to get rid of my mold and poor air flow."

"Environmental Resources efficiently and effectively removed the asbestos-coated ductwork in my kitchen wall so that my remodel could proceed on target. After my kitchen remodel was complete, I found what I thought was exposed asbestos on the top of the ductwork in my basement (in a different location from where they had worked). I called and they came out the next morning. They confirmed it was not asbestos. And then they spent the next hour cleaning up the kitchen remodel rubble that had fallen onto the top of the basement ductwork and that I had been unable to reach. Not their mess. Someone else's. At no charge. This level of service is unheard of."

"We hired Jeff to give us pre and post mold remediation air quality tests, and I am so glad we did. Jeff was extremely knowledgeable and had no conflict of interest on the outcome of the results since we had a different company doing the remediation. We actually had to go back to the mold remediation company when his air quality report did not pass clearance, and he was our chief advocate in getting the company to come back and do further remediation. He has been a great to work with because he is not only an expert but is a caring individual, and I would recommend anybody use his services. He also is licensed to test for asbestos, which is our next project before we remove our popcorn ceiling!"
