"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."

"They were responsive to every call, did the work professionally and cleaned up nicely. We would not hesitate to recommend them to friends and family. We had two leaning columns in the back yard that are now straight and piered so they will never shift again. They then removed a large area of cracked cement and relayed. It looks fantastic!
