Unfortunately, I recently found that I had a rather significant amount of mouse droppings in an unfinished basement area used only for storage. I was delighted by Gary’s cleanup of the area this week which is now spotless. Gary and his team impressed me with their communication, follow-up, punctuality, professionalism, and most importantly, knowledge of the chemicals for a safe clean-up of my basement. He even went the extra mile to identify how the mice gained entry to the house. While this is an not inexpensive service, it was worth it based on the result and peace of mind. Five stars!

Amy & Sterling are by far the best duo to help clean & pack. They worked hard and were very professional. Thank you Gary for sending 2 of your best employees. I would definitely recommend this company!

Wow. Gary and his team are amazing. My little sister was about to get kicked out of an apartment because the hoarding was so bad. They cleaned everything so it was like a brand new place. The landlord thought she was in the wrong apartment. No more smell. They were great with helping my sister sort and organize. Gary even helped to clean out the car. The work would have taken me two weeks. They had it done in a day. Worth every penny!

Words can not fully express how incredible Gary and the Bio-One KC team were to work with, but I will try. First and foremost they are absolute professionals, quick to respond, honest and complete in their estimate, great and consistent communication, and delivered exceptional service that exceeded my expectations. Maybe as important as the quality of work is the compassion and understanding they showed in a very difficult situation. I had a family emergency and I needed their services very quickly and unexpectedly. I was completely overwhelmed with all that I needed to do, and potentially having to navigate many vendors in a short time frame, it seemed impossible. Gary and his team were able to provide me with a one-stop-shop and able to get me 90% of the way complete with the job at hand and provide references to other service providers whom I could trust to get me 100% there. In an emotionally difficult time you need a company you can trust and that believes in not just getting the work done, but caring for the people involved. Gary's support and reassurance during this process is something I will never forget and always appreciate. This is a company that delivers in both integrity and excellence in their work. Pros: Honest and accurate estimate, no surprises. Professional and thoughtful staff. Complete service highly customized to the needs of each client. Quick response. Fair prices - particularly for the quality of work. References to other trusted services and vendors for other services needed. Cons: None

Outstanding customer service. A rental of mines had waste in the basement leftover from a mainline being clogged. BioOne came over and I received a fair estimate. I had to reschedule due to major pipe problems. Gary was understanding and a few weeks later a tech came out and cleaned everything up perfectly. My tenants were happy and complimented the great work. Gary worked with me from beginning to end and made it very easy since I live out of state. If you’re looking for an honest & caring company, you’ve came to the right place! Thanks again!
