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

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!

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.

Thank you Jason for arriving to check my problem less than 2 hours of my call. Jason checked all around the affected area and gave me excellent advice on how to handle it. Jason is efficient and his advice was effective and useful. I am very happy I called Bio-One and will call again if needed.

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

Great job. Jason helped me out of a bind at the last minute and was very professional, patient and efficient in his work. I highly recommend and will use his company again in the future.

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.

During a most difficult time, Bio-One Chula Vista showed incredible compassion to our family during a difficult time.

I can’t say enough good things about Jason and Jason! I was extremely overwhelmed with helping my family after we received some devastating medical news that required them to make an immediate lifestyle change. I came from out of town and found that their house was infested with mice and just cluttered beyond anything I’ve seen before. The mice were hiding in the garage and several pieces of furniture in the house. Jason came over and walked through the house with me. He was direct and honest about his recommendations. He had zero judgement, and was extremely easy to work with. He quoted a reasonable price for the undertaking. He showed up on Saturday with a big truck and another Jason, and they loaded everything that was covered in mouse droppings from the garage and even walked through the house to help remove things. First of all, they worked so hard! Mice were coming out of everywhere, and these were not great working conditions, but they gave my family their garage back, and came through the house and took out the furniture that was not easy to reach. This is probably my longest review, but I’ve never encountered any business like this. My dad, who is disabled, even told them that they saved his life. I agree! They absolutely restored hope in so many ways. Most importantly, they helped my Vietnam veteran grandfather come around and get comfortable with the idea of getting rid of things. It was so hard for him, and they were very patient with us through the whole process. It helped that they asked questions about his life and hobbies, and took care to only take things that needed to be removed. By the end, my grandfather was willingly giving away things. Thank you so much!!!

I was ashamed of my place before Bio-One whirled through it. Now I can confidently have people over and not be afraid to show pics of just normal day activities at home. 10/10 recommend to anyone needing a thorough cleaning service. I never took before pics but these are ones taken my Jason and his team. The after I took. It's a huge improvement.

Jason Madsen and his staff at Bio-One are punctual, flexible, friendly, and efficient. I had a really difficult personal situation and needed their services on short notice. Jason was understanding and helped me out when I was struggling to find anyone who would. The staff at Bio-One are professional and efficient and my job was done in just a couple hours. I would absolutely recommend their services to anyone who needs serious cleaning done quickly and professionally.
