House went from uninhabitable back to desirable in just 4 days! The crew worked very hard, despite a couple of illnesses among co-workers. They went above and beyond, even jumping in the dumpster when I thought I threw something out that I shouldn't have. Such dedication and always had smiles on their faces.

God sent us two angels of the worst day of my family’s life. Ryan and Kristi came to us after a very tragic murder/suicide occurred in my parents home. They did a fabulous job cleaning all areas affected. The energy of the house shifted to peace despise such a horrible incident. They absolutely went above and beyond for my mother in her time of need. We can’t say enough nice things about them. They really took the time and spent long hours to make sure everything was spotless. We can’t thank them enough. ❤️

Working in end-of-life care, we’re usually the ones offering comfort and support—so it was incredibly meaningful to be on the receiving end of such genuine compassion. From start to finish, Bio-One brought us peace during a difficult time. Ryan, in particular, showed such care and empathy. It was truly refreshing and deeply appreciated. From here on out, Bio-One will be the only disaster cleanup company we recommend and promote.

We had a great experience working with Kristi and Ryan. They did all of the work we agreed upon, helped us clear out trash and recycling and did it at a fair price.

Ryan, Kristi and Dan, I cannot that you enough. You made an awful situation just a little more bearable. Not only did you do a phenomenal job but you also were there for me and made me feel like family. You truly are a remarkable team!!! Lisa & Jon

I can't express how awesome of an experience it was to have witnessed what this company is capable of doing. In two days they turned a nightmare into a new positive outlook for me. Danny, Chase, Oscar and Toby were very professional and made it easy on me. The owner Ryan is a very compassionate helpful man who also made this experience very easy. I can not recommend these guys enough.

Where to start..Bio-One Delaware came to our rescue almost immediately , on a Friday despite a heavy schedule.First, Ryan was so helpful on all aspects what to expect of the job.He sent his lead Dan who brought with him Oscar, Freedom and later Christian and they did a magnificent job of cleaning up a very nasty sewage problem. They were fast, efficient, considerate,and so polite. I could go on forever. If something happens this is the team to call!!!!! We are forever grateful to all of them!

I called Bio-One after weeks of a horrible smell in our office like an open sewer. We had our HVAC company, 3 different plumbers, a roofer and 3 inspectors go through our building, and NO ONE could find the source of the smell!!! Finally, we had a client refer another plumber to our office. He showed up and did what all the other plumbers had done, but then he went above & beyond his job and was searching around in our drop ceiling. He was in the office where the smell was strongest and to our surprise, he found dead mice and a TON of mouse droppings and nests. I emailed Bio-One and that same day I received a call from Ryan. I explained our situation and he was able to get us on the schedule for an inspection to see if we needed remediation of the mice and their mess. He explained everything to me in great detail during his inspection and was able to get us set up for a clean-up appointment that same week. We had to move it to the following week due to some work deadlines. Kevin & his partner were here yesterday and if I hadn't let everyone in the office know they were here they would have never noticed them. They were very quiet & discreet even while running the machines they had to use including a vacuum cleaner. They were very professional and cleaned up everything after removing 4 drop ceiling tiles, rodent droppings and carcasses. They used a type of fog machine up inside our drop ceiling that dispersed a disinfectant that traveled through the entire building making any & all organic matter 100% inert in case there were any areas the mice were living that we hadn't noticed we wouldn't smell anything anymore. After over 7 weeks of sitting in the office for 12-15 hours a day 7 days a week (tax season we work almost around the clock) there was NO smell! NOTHING! The other people in the far side of the office made comment that their side of the building smelled ""fresher"" this morning and asked me if I had cleaned or vacuumed the common area. I was so happy that everyone noticed the lack of odor. If you need a company for clean-up or remediation I would 100% recommend Bio-One! They were in constant contact with me before & after each visit. While in the building they were extremely professional and polite. They were clean and neat and left the office space cleaner than they found it. They even put up 4 1/2 new ceiling tiles (I provided) to replace the 4 1/2 that they had to remove and dispose of at no charge. Having to deal with this rodent problem in an office full of women was a nightmare but Ryan at Bio-One answered all of my questions and made the removal very easy. I truly appreciate all they did for us! Thank You!!!!

I had a waste issue that prevented my AC and plumbing company from fixing a sewage pipe. Ryan immediately sent his crew (Oscar and Toby), and they were able to remove the waste so the plumber could replace the pipe in a crawl space. Oscar and Toby worked so hard they passed up a meal to complete the job. When something like this happens you feel helpless because you're limited to companies who specialize in this removal. Bio-One was a life saver.

Ryan, Kristi and "St. Nick" the man (LOL!) were just the Christmas miracle I needed! The past few years have been nothing but physical and mental turmoil in our lives due to family deaths, physical disabilities and personal health challenges. Ordinary household chores have become difficult and our tiny 2 bedroom apartment was slowly starting to turn into a hoarding situation. It was so overwhelming and I needed help quickly to declutter and restore order to our home while my husband was out having open-heart surgery. I wanted him to return home to a clean, non-chaotic environment, but did not have the physical strength or mental energy to do it on my own. One quick phone call to Bio-One saved the day! The very next day Ryan and Kristi viewed our apartment, gave me a reasonable quote, and within the same week accomplished in 3 days what would have taken me months to clear out and clean. They were friendly, empathetic, and non-judgemental and worked until I was satisfied with the outcome. God used them to perform a miracle for me that I didn't think was possible. I highly recommend their services. Don't hesitate to call them; it will be worth it in the end!
