Diego and his crew were so kind and helpful during our time of loss. They did such a wonderful job cleaning and disinfecting the area. It was a pleasure working with people who make a difficult time so much easier. I strongly recommend Bio-One of San Francisco for this specific type of cleaning.

Bio-One San Francisco was quick, professional, and thorough. Highly recommend!

From the first call I made, Diego was communicative and patiently explained the process and fees involved. He quickly made a plan with me and he and his crew did a fantastic job, cleaning up a huge mess in one day. Perfect service, would definitely be happy to do business again.

Due to the unexpected and sudden death of a sibling two other siblings and I had to immediately travel across the country to California to handle our sibling’s affairs and the disposition of his possessions. Upon our arrival at his apartment we were completely overwhelmed as to how to handle the enormous task at hand within the few days we had in which to complete it. Through an internet search I found Bio-One of San Francisco. The various services advertised seemed to be exactly what we needed. I reached out and my call was immediately answered by Diego. Within hours he met us at the apartment to assess the situation. He was very calm and reassuring about his team being able to get the job done in the timeframe we had. One day later his team arrived and the work began. The compassion, sensitivity and respect for the situation by each and every team member was far and above anything I could have hoped for. We simply could not imagine that this job could be completed in 2 days but it was! Not only did the team assist us in getting the apartment completely emptied but they very thoroughly cleaned it as well. I don’t typically write reviews but I had to write one for this company. I so highly recommend this company and their team to get the job done with the sensitivity and compassion needed to assist in the midst of grief and an incredibly challenging and overwhelming situation.

Miracle workers! This team did such a great job — they were helpful, professional, really good communicators, and very detail-oriented. I'm very detail-oriented myself and it takes one to know one.😉 Can't recommend them enough!

These are very trustworthy guys. They won’t let you down.

Diego and his crew were very professional and understanding during the clean up of my relatives house. I never felt judged or embarrassed at any time during the process despite the huge mess my family member left. The price was very fair and I would not hesitate to recommend Diego and Bio One to anyone in need of his services!

I could not be happier that I hired this company. Th

Very reliable and professional, i would recommend this company to everyone you will not regret it

I had a great experience with Diego and his team from Bio-one. They were very professional and did a great job! I could not have asked for a better service! Thank uou Diego!
