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!

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.

Bio-One Chula Vista did an awesome job cleaning the house! They did a more thorough job and at a better price than what other companies offered. They went above and beyond. The crew got floors, counters and showers clean that I thought were impossibly stained. They sorted and retrieved precious family heirlooms and valuable items. The guys even did an extra good job detail cleaning my aunt’s room because she has allergies and asthma. Jason honored the original estimate, even though it was more work than originally thought and stayed late to get the job done. He communicated and documented throughout the job. I highly recommend Bio-One Chula Vista!

The owner's name is Jason. He is extremely responsive and understanding. My situation was very stressful and he took the time to listen and provide a solution to help me move forward. I strongly recommend working with him and his company.

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!

Jason and his company were great! He answered the phone himself at 10pm at night and met me the next day based on my schedule availability. He went above and beyond during an emotionally difficult time. His professionalism and kindness made the whole process so much better than I could have ever imagined. Would highly recommend Bio-one to anyone who may need the services this company offers.

Jason and his team have been great! They get the job done while maintaining professionalism and integrity. Bio One is on speed dial for all of my property needs. Junk removal, mold remediation, de-odorizing, they have always exceeded my expectations. I can’t recommend enough!

An absolutely wonderful service, with easily the best value in San Diego. The speed, efficiency, and care taken is unrivaled. A company that cares, a company that's efficient. I had a problem that would have taken me months, if not years, to do on my own, and they managed to pull it off in three days. They managed to sift through things and keep a lot of things I wanted to keep, unlike many businesses that'd toss near everything. Truly delivers the help that I needed.

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.

I didn't realize before meeting Jason, the importance and necessity of his service as an imperative part of a healthy and functioning society. What his business provides is the work that most people don't think about, the hard but real situations many elderly and debilitated people live in that are unsafe and unsanitary. Jason is very compassionate and takes pride in helping people improve the situation they are living in by cleaning up and helping his clients find resources to improve their wellbeing. He doesn't stop at what his service provides, but gives people options and solutions so that they can avoid another disaster. He is incredibly responsive and will do anything he can to fix the problem. Thank you Jason and Bio-One Chula Vista for your hard and important work.

I can't thank them enough for their help in getting my home safe and clean again. Jason and his team were very respectful of my home and made sure to keep me aware of everything going on during the process of cleaning up. They were so helpful, polite, and very professional . They marked everything off on my list for them and even more! I definitely recommend them!

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

Jason was easy to communicate with, prompt and very clear on what process he would be doing in the space. Thanks Jason!

Wow! What a difference! My home is actually a home again! Jason and his team were very kind and respectful, getting things organized and accessible. I so appreciate their hard work and highly recommend them.

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.

I had a situation where I needed covid clean up fast. I had called several other companies and was put on hold or they will call me back in a couple of hours. I calle Bio One and Jason answer said he would be here at 2:30pm and he showed up on time gave me a quote on the spot and took care of the job! Thank you Jason it gives me peace of mind that we are able to continue to work in a disinfectant environment!

Jason and Steve know their stuff, and they are very personable & professional. They got to the root of our mold problem, took care of it quickly and educated us throughout the process. We are glad that we used their services.

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.

I needed my house Covid sanitized before i can put it in the market. Working with Jason was a breeze! I needed a weekend appointment and he was very accommodating. Scheduling was a breeze and he showed up early. . Very professional! 👍👍

Amazing service, and on time, thanks! If you need a place disinfected, call Jason!

BIO-ONE did a great job with rat feces 🐀💩clean up in my attic. My attic has a small crawl space and it was ALOT of work in a very confined area. They were friendly to me and my two dogs 🐕 🐶. They really took pride in their work and I"m very happy with the results. Thank you Bio-One!

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

I recently worked with Bio-One Chula Vista. They delivered on everything they promised and finished early.

Jason Madsen was extremely helpful and provided excellent quality work. He was able to address all questions and concerns that I had.

When the worst things happen, it's good to know that there are still people out there to help. Thank you so much Bio-One for your professionalism and your thorough work.

I wanted to thank Jason at Bio-One for being so professional and considerate in our time of need.

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

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

BioOne is fantastic, and they arrive in an hour!

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

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.

Bio- one is a new local company that is going to do a wonderful job for you in the worst of times. Give them a call.

I started working for BIO-ONE, under the guidance of Jason Madsen in January of this year. Being an Environmental Engineer, relocated from Northern California and former US Army Ranger I have been absolutely impressed with the level of professionalism and integrity that he has displayed. B.D.

Quick & easy service! Jason reached out right away to set up services & had the job done within an hour the following day. Thorough job! Would highly recommend to anyone looking for any kind of biohazard cleaning services. Thank you Jason!

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 did a great job! Very professional and friendly!
