"TESTING FOR ASBESTOS I need to make sure people know about a man named Jeff Miller Owner of Scope Environmental. I wanted to have my basement checked for Asbestos. This man was absolutely the nicest person. Jeff is a professional, who explained things extremely well and in detail, offered positives suggestions, and extremely knowledgeable. Oh, and extremely honest and helpful. If you ever want to have your basement checked for Radon or Asbestos or Mold, please call this nice man who has a vast amount of experience and knowledge on these three issues. His phone number is 314-220-1810. His pricing is very reasonable and he is Certified in the State of Missouri which is a requirement by the State to do testing. He sure put my mind at peace."

"It went great! They set up a system in my parent's house and they mitigated the radon down to a save level. They did a test before and after, and I was satisfied with the results. Proper Environmental did a thorough job and would recommend this company to anyone!"

"We wanted the house inspected because we were buying it. He did a thorough enough job of examining the outside and inside of the house. One thing that he didn't do... He didn't pull some building materials away from the basement storage area to examine the basement wall for cracks. I was a little surprised about that. He also didn't notice that the basement door was getting stuck when we tried to close it. We noticed it ourselves and asked the current homeowner's to fix it. However, he did notice the slow drain in the master bath. A leaky window in the master bedroom and that their was no GFCI outlet in one of the bathrooms. He tested for water/dampness in all the rooms and all of the windows. He communicated well and arrived on time. He took about an hour outside and inside. Also looked for termite problems in the house as well. Overall, I would hire him again."
