Thank you for trusting us.
We're ready to serve you!

Words cannot express the thanks and gratitude I have for Bio-One of Worcester! Mike and his son came to our aid after one of our cats created for herself a bathroom in a crawl space in our split level home, which also went under the lower staircase. This dynamic duo wasted no time getting everything clean again! They accommodated us on many levels including working in a swelteringly hot airless environment to cleaning up, as well as visiting us three times to make sure the area had responded to the treatments, coupled with the utmost respect and courtesty for our situation! I highly recommend Bio-One and will definitely use them again!

Mike and his team helped me work through a very difficult time. They made sure to ask if I was ok during the process of removing my family's personal items. They made sore I felt safe and also involved.

Prompt, superior service and thorough work!

Mike was recommended to us by the Worcester Detectives. I can see why they would recommend him. I certainly wouldn’t hesitate recommending him and his team. If I could give 10 stars, I would. I can’t even find the right words to thank Mike Belanger for his help. He was discreet, helpful, neat, understanding, great communicator, fast worker, listener, the best of the best. Mike worked with me, from out of state until I could get there. Of course, it’s hard to think clearly during time of mourning, but I honestly didn’t need my brain with Mike. He thought of everything. He handled everything from biohazard, clean up after death, to a remarkably quick clean out of an overstuffed condo quickly, neatly, and discreetly. From tiny items to the heaviest of items, all were removed. Mike is an extremely intelligent, knowledgeable, compassionate man. There isn’t an ounce of hesitation, on my part to recommend him. My family is beyond appreciative to him. You won’t be sorry picking him for an uncomfortable project that confronts you. I promise you.

Mike and his team were honest, prompt and thorough. They made us very comfortable and explained the process and cleaners they use. Very friendly to my family and offered help to us as we cleared other household items into dumpsters. I would highly recommend them to anyone who needs to clean up done right.

This is an amazing company. They cleaned out a house in Millis in no time. They loaded multiple 30 yard dumpsters with gunk and waste in less than a week. What a great company to work with.

I'll add to all of the great reviews here. Mike and his crew did a great job. Mike is the kind of communicator you wish you had for all of your service calls, and he asks all the right questions and handles everything. He delivered on time and on the estimated cost, and working with him was a real bright spot in an otherwise very difficult time. Can't recommend enough. Thank you so much, Mike.

In May of 2024, I called Mike at Bio-One and he quickly set up an appointment to visit my home in Worcester, MA. A shed attached to my house, the crawl space above it and a finished room in my basement had an infestation of mice and squirrels and their urine and feces were causing dangerous odors and more. Mike is a smart, experienced and trained investigator so he was able to find the source of my problems and to provide a well-planned out solution to my critter problems. I highly recommend Mike and Bio-One to anyone who needs the right and affordable guy and business to provide advice and actions to resolve a wide variety of hazardous conditions. Gary R

Mike and the Crew are the most motivated, caring, considerate group of people I have met in a very long time. They restored my belief that people when given the chance will choose to do good. My son and I were struggling in our home the over the years had become a cluttered up hoarders nest. We also were going through a very dramatic change of wife of 30 years died very unexpectedly just a month after our 25th wedding anniversary. She had been pretty sick for a couple of months. The doctor she saw in the afternoon 11 hours before I found her unresponsive on the porch seemed to believe she was on the mend. I was put in touch with Mike by a state agency. We met and he, made it his mission to give my son and I a clean slate to rebuild our live after our loss. That he and crew did with incredible speed and care. The dumpster was filled to the brim in 6 hours. Not everything we would liked to see happen happened because of the short time frame available. I am so happy. I can walk from one end of the house to the other with the lights off at night just by ambient light coming through the windows without fear of tripping and falling. I can clearly see and access the things that need to be repaired. My son is now helping keep the space clean because he's not overwhelmed by the enormous mess that was once our house. Thank you Mike and the crew, for giving us a clean and manageable house and a new outlook on life. Without their help I'd still be putting a few extra trash bags curbside each week never really making headway. Mike is a creative man and his positive outlook is infectious. Whatever your situation is Mike will find a way to help. As he did for me and my son.

Bio One was so professional and compassionate. We cannot thank them enough for the very thorough job they did! The car looks like brand new.
