decontamination and biohazard cleaning services reviews
Sandra Robbins, Columbia, 04/2025
Awesome! Ivan & Yolanda and their team did a wonderful job of clearing out and cleaning and sanitizing a 60’x30’ workshop that had ac... cumulated 30 years of dirt and grime. The process was quick and easy, the best part was they were able to complete the job from estimate to work completion in five days. They took care of all the details, including arranging for the dumpster and kept me updated along the way. Highly recommend.  Read more >

Iman Ahmad-Sediqe, Columbia, 03/2025
They were able to remove a stain in our car that we had completely given up on ever getting out— we bought a used car which had a deep blood...  stain, we had the car detailed several times and it was only with their professional work that it was finally cleared. They were incredibly communicative, very sensitive to our situation and handled the entire process with such grace and care.  Read more >
