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.

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!

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!

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.

I hired Bio-One to remove sewage from the crawlspace in my house, and they did an excellent job. They were prompt, professional, and thorough. Their team was respectful of my property and made a stressful situation more manageable. I highly recommend their services to anyone dealing with a similar issue.

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.

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.

Calling Ryan was one of many difficult phone calls I had to make after my late wife's unexpected passing. He, Nick, and Dan did an outstanding job helping me with the clean up after a very painful loss. Not only were they professional about it, they also treated me like I was friends or family during the entire process.
