"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!"

"K&E was very responsive to my request through Angi and came the same day (a Saturday) to review the work. He gave a reasonable estimate and completed the work the following Monday. I really appreciated the quick turnaround. However, he did not provide the contractcertifications and company info prior to coming to do the work as he said. He was not responsive to my emails and text messages about the contract and work start due to bad weather. Clean up was pretty good, but I did find chipped paint debris when I expected to all of that vacuumed away. That's why I gave a 4 point rating rather than a 5. I will not need to hire again because the lead and asbestos have been abated and there is no need for further work."
