"I received my call earlier today, and discussed my concerns. I wanted to start the process toward remediation asap! Mr. Griffin was at my house 4 hrs later. He was professional, compassionate, and answered all my questions, since this was a new experience for me and of concern. By 3pm, my home was totally inspected and my airborne samples were collected and headed to the GA lab for testing and results. Within minutes, a email to track my lab results status was sent to my phone! I can't do anything until the results are determined,and Mr. Turner, Senior Mold Analyst gets the report! The ball is rolling! MsV"

"Very well. Will serviced the house. He suspected there could be mold in the ducts, because there wasn't any in the furnace itself. I had burning sensations in my eyes and throat and that usually is generated by mold. The burning continues, so I'm not sure there was a mold issue, but I'm glad I had the service done just in case there was. Will is very professional. Explained everything that he was going to do. He left the house in the same condition as when he arrived. Also, he was quick to say that if I had any problems in the future, he would be glad to come back."

"Eric and his crew, Christopher and Joe, did a great job. Eric informed us of his three day plan to complete the job and it went exactly as he stated. They showed up on time and kept us informed throughout the process. The price was fair and exactly as quoted. In addition, they were courteous and professional. I highly recommend Fox Environmental Services."

"We had a good experience with this company performing mold removal and installation of a water proofing system in our basement. They took the extra time to really evaluate the mold and water issues we had in our basement and explained in detail all of our options and the process involved in the resolution. The crew was knowledgeable, and professional. They reviewed the scope of work with us to make sure we were pleased with the process and results. They showed us pictures of the progress, tested the system sump pump in front of us, and went over how everything was put together and how the system will function. They also provide a good comprehensive warranty on the system. We'd recommend this company to anyone out there with similar issues in their basement."
