Thank you for trusting us.
We're ready to serve you!

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!

I can’t say enough good things about my experience with Jason from Bio One... But one thing that really stood out in this whole hoarding/decluttering process (which was so hard & emotional for me) is that he made me feel comfortable not only by his professionalism but by his kindness & understanding as well. I thank you so much Jason! Sincerely, Justyne Meza

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.

Jason and his Bio One team helped my family out with some extreme cleaning. The before and after was dramatic and well appreciated.

Great service and friendly to work with in trying times! So thankful for their timeliness and attention to detail!

Just recently I have called upon Bio-One of Chula Vista for a second time. Face it, if you need their services, you are already very stressed. I was so impressed with their amazing service, care, and pricing the first time they helped me (Mom was a serious hoarder), that when I simply couldn't face a second cleanup two years later, I called them. I called from outside my mother's ER room. Even at 8pm, my call was answered and arrangements were made. First, every other company I spoke with charges by the day. Bio-One charges by THE JOB. The amount of $$$ that can be saved is staggering. (BTW, be sure you get the right Bio-One, there's another with a very similar name.) Yes, the service is fast and complete. But here's what I find most valuable: the sincere care that I've recieved during the worst of circumstances. The option to be on site or not was completely up to me. I stayed, I felt like I needed to be there. While my skin is crawling with what these gentlemen had to handle, to them, it's no big deal. Really, honestly, not at all. Not a wince, not an upturned nose, nothing. And they're terribly personable. This combination made this horrible experience much less horrible. You'd think they were planting rows of daisies whistling while they work. Their attitude greatly helped me and it's much appreciated. If you find yourself in need of this type of service, call these guys first. I promise, you won't be disappointed.

We are very grateful to Jason and Bio-One for the wonderful job they did cleaning the room of our family member. He was able to give us a quote the same day we called and finished the job the next day in just a few hours. They cleaned everything to perfection and hauled all the trash and junk. Could not have done it without them! Don't hesitate and give them a call!

My neighbor recently needed some help with a hoarding issue, so I called Bio-One on her behalf. They were super helpful and did a job no one else wanted to do. Definitely recommend.

Jason and his team at Bio-One are just incredible! We've used them for a couple of high quantity hoarder cleanups as well as human remains bio- remediation. They went above and beyond on each and every project. Not only can they handle serious cleanups, but are also very careful to find specific items that might be of value to family members, beneficiaries, etc. I highly recommend Bio-One for your property clean up needs!
