"The Mold One Missouri was very professional from the start to the end. They even came back to our house to redo a mold test in one of the rooms. All this happened September 2022."

"My review is tiered because the overall service seems to run on tiers. The technician was great. Very personable and professional. 5 stars for his work. Your tests get sent to the lab. The lab explains the results and recommends a company for a DIY solution. This is where things start to fall apart. The company you get referred to has abysmal reviews and the sales pitch feels extremely predatory. That taints my opinion of the lab results which would be teamed up with a business they probably shouldn't recommend. We're planning on either an independent company locally to get a quote from for any remediations we will take or even see what home depot has to offer. In any event please read the reviews of BioCide, the company they will recommend you use. We're still not sure we even have a real problem if they are working together."

"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."

"The best thing about my basement flooding was that Nutech made it very easy to get my basement and house back in order with very little time lost on my end. I would recommend them to anyone and Shawn (sales manager) is one of the best guys to work with in the business. He's honest, hardworking, and very easy to talk to and reach."
