What our clients say

decontamination and biohazard cleaning services reviews
Carol Chase, Waukesha, 3/1/2025
Bio-One did a great job for me. Very professional and they knew what to do. Came in on time and budget! I had a horrible mouse infestation that had been going on for years. Lots of mess and damage and they cleaned it all up. Plus, they consulted with me, ensuring that my mouse problem was eradicated before they came in to do the cleanup so that my effort would not be wasted. Very reliable highly recommend!
decontamination and biohazard cleaning services reviews
Jim Morales, Waukesha, 10/1/2024
Getting rid of things you've amassed over a lifetime can not only be difficult and deeply personal, but knowing who to trust to handle it for you can add to the stress. Andrew and the crew at Bio-One of Milwaukee made everything, and I do mean EVERYTHING a breeze. From the initial estimate to the last box out the door, the Bio-One folks were all thorough and professional. Perhaps most importantly, they were deeply concerned on a personal level that the experience was stress-free and everything I needed it to be, including the fact that the owner was on-site with his crew the whole time! Bio-One is not a low-cost provider, but you will not regret the minimal extra expense to have your cleanup and removal handled with their amazing quality of service. If had known that there was someone of Andrew and his crew's caliber available, I would have hired them years earlier. Not joking. Years! Call Andrew. Get an estimate. It will only take 5 minutes of chatting with him to realize that you made the right call. Thanks Bio-One!
