"I used Scope Environmental recently to test floor tile and the underlying mastic to determine if either contained asbestos. I selected Scope because Jeff was very responsive, professional, independent of the abatement companies and his price was competitive. Jeff suggested testing both the tiles and mastic. The tiles tested positive for asbestos but the mastic contained no asbestos. As a result, I saved considerable expense by abating the tiles only and not the mastic so I also used Scope again for the post abatement air testing rather than the abatement company. I would hire Scope again for material and air testing for asbestos, mold or any other potentially toxic materials."

"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."
