Great business, i do a lot of business with them. Very professional.

Jason and his crew were very helpful during a difficult situation. They handled everything professional. I would definitely recommend their service.

He was on time. And was reasonably priced. Crew was professional and courteous.

Hard working crew, and extremely reliable. We have several issues with cleaning out hoarder and dump sites, and the Bio-One crew is never afraid to tackle the nastiest of jobs. Their tenacity is appreciated, and I highly recommend them for these types of jobs and clean-ups. Thanks!

Jason and his team did a fabulous job in rodent infestation removal and sanitization in a travel trailer. He was prompt in getting the job done - very professional and thorough. His price was very fair and we wouldn't hesitate to use this company again!! Looked so good, it sold immediately!

A bio cleanup company isn't something you ever think you need, but when I did, Bio One Chula Vista came and put everything right again. The owner Jason Madsen couldn't have been more professional. Jason and his staff were very considerate and extremely great at their jobs. I highly recommend this company.

My studio was in a pretty bad state after a bad mental health situation caused it to get this bad but Jason and his crew cleaned it up so incredibly well that I won't be ashamed to have people come over finally. I'm extremely pleased with the outcome and definitely recommend them for any clean up job.

Outstanding Service After a tragic situation in one of the units, there was a lingering odor and extensive biohazard cleanup needed in the apartment after police removed the more then a week old one of my greatest resident’s dead body. I can’t thank Jason at Bio-One enough for the incredible job he did with Gary. From the moment I reached out, Jason was so easy and professional and respectful of my stressed out situation as a manager. Jason and Gary arrived promptly right after the medical examiner ok'd to enter the apartment, Bio-One handled everything efficiently removing the week or more lingering odors and thoroughly cleaning up all traces of biohazard materials. They also throw all the (hording) belongings. Their expertise in removing the odor and thoroughly cleaning up body fluids left even under the bathtub and under tiles and floors, removing and cleaning everything in the unit that smells. The best part was they communicated clearly and honestly throughout the entire process. Not to forget they kept following up and checking until making sure it's all in their and our satisfaction before they sent their reasonable invoice. Thank you for making this situation manageable. I highly recommend Bio-One to anyone in need of biohazard services.

Recently I had a need to disinfect a small rental property. Jason was on site within one hour of my call and was extremely professional providing the service. I feel very comfortable and confident with the result of his work.

In the most stressful time possible, when the unexpected and shocking events of life happens, these are THE best professionals to step in and help. Jason provides the most timely comprehensive expertise how to best accomplish the specific needs of a situation. With a clear understanding of a family's objective on what needs to be addressed, his excellent communication and insight truly help to lessen the weight of accomplishing what seems overwhelming. We are so very grateful for his compassionate understanding of the situation and an amazing sanitizing job. What a relief to have found superb authorities cleanup and biohazard. Thank you so very very much!!
