What our clients say
Robert Onaga, San Francisco, 07/2025
If you've ever seen the show hoarders, then you need a team like this one to help you out. Diego and his team were hard-working, communicative every step of the way and very understanding/compassionate throughout the whole cleanup process. The project we hired them for was easily worse than many of the hoarders episodes. Tons and tons (literally) of e-waste, biohazard waste, and things that would condemn a home in a heartbeat. They didn't bat an eye and did everything from junk removal, biohazard remediation, to deep cleaning of the home. They brought a 40 cubic yard dump truck and hauled away 5 dump trucks worth. Every day was a noticeable achievement. What we thought was an insurmountable project suddenly became doable. And most of all, the amount of burden Diego and his team lifted off our shoulders (literally and figuratively) was incredible. Given the scope of work and our timeline (mine, not Diego's) we stopped about 2/3 of the way through and hope to have Diego and his team back out on site later in the year to finish up the remaining 1/3. 100% would recommend his team to anyone.
Laura Saunders, San Francisco, 07/2025
Diego and team are fantastic. They are smart, hard-working, respectful, and kind. I had a hoarding cleaning - they worked with my limits, found things I needed them to find, found other things (a passport!) that I hadn't even asked them to find, and in 2 days transformed my house from a toxic site to a home. Part of my direction was to save all photos, books, and paperwork. It took longer, but they stacked them neatly around the edges, by category, making it much easier for me to deal with them. I heartily recommend Bio One of San Francisco. They are safe to work with and worth the money!
K. Ford, San Francisco, 06/2025
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!
