I can not give Tom and his staff enough praise. They were wonderful and professional in all ways. Lance came out to give us the estimate we needed and was curious and a pleasure to deal with. Excellent customer service. I highly recommend.

I highly recommend Tom and Bio-One. He was amazing from the first phone call. He handed a delicate situation for us and was very helpful for further recommendations. He was prompt and helpful in resolving the problems. We were in town for only a few days and he was quick to help us resolve all. He went the extra mile and did a great job! Professional, accommodating and very helpful in a stressful situation.

Tom and his team promptly responded to my need for a home cleaning after a COVID quarantine. They were extremely accommodating despite my last-minute request. They made it to my house within a day of contacting them and kept me updated the entire time. Once at my house, they worked efficiently and even offered to extend their services to sanitize my car. They went above and beyond for me and also happen to be some of the friendliest people I've come across. I would highly recommend Tom and Bio-One!
