This is the second time I have used Bio-One PDX for cleaning and I plan on using them for more projects in the future. They are professional, efficient and truly care about the work they do. I highly recommend their services; it is worth every penny.

Given the kind of work that Bio-One does -- cleaning-up horrendous messes -- they're not likely to get a lot of customers who will write reviews on Yelp. That's a shame, because these wonderful people deserve mountains of praise for what they do and the great way they do it. I had a relative who needed their services recently and we found Bio-One's entire crew to embody all the good adjectives: professional, kind -- so, so, kind --, honest, caring, patient, fast, thorough ... I could go on. Most of all, they enjoy helping people and bring a lot of heart to what they do and that made the hard work easier to bear. On a more tactical level, they use mostly their own employees, not day laborers. That's a major reason we chose them and, I think, that has much to do with how thrilled we are with their work. So, if you are in the unfortunate position of needing their kind of services, then you have my sympathies and one emphatic recommendation to use Bio-One.

This company blew me away with their excellent service, but even more with the compassionate way they provided cleanup of a tragic event so the parents would not have to face the carnage. I would never use a different company if I ever needed one in the future. This family owned company really cares about the people they serve. I would recommend them for any job. Cleanliness with Care and Compassion. You won't find this anywhere else at this level.

I contacted Bio-One to assess cleaning and decontaminating the attic and basement of my home from years of undetected rodent infestation. And when I say cleaned out, I mean they removed and disposed of all debris, insulation, and unwanted junk from these areas. He then sanitized both areas with a decontamination enzyme, cleaning shelves/floors/attic beams, even the basement crawlspace. Phil the owner did the work himself, and was a pleasure to work with. All I had to do was mark the items in the basement I wanted to keep, and he took care of the rest, saving me from conducting hazardous cleaning work. Phil was very professional and respectful of both me and my home, and understanding, and he worked very fast (took less than 2 days total). Unlike another company I contacted to do the same work, Bio-One used an effective combination of decontamination/deodorizing products (not just something to mask the odor) as well as and enzyme product to further clean/decontaminate the beams and floors. On top of all that, they removed all the random boxes and junk from my basement whether it was contaminated or not (bonus), and cleaned everything that was to be left behind! Phil and his assistant took steps to ensure there was no mess left behind on the way to/from the attic and basement, and wore industrial PPE gear themselves during the whole process, a mark of true professionals (trust me, you don't want someone cleaning out rodent mess without properly protecting your home as well as themselves, not doing so indicates they don't know what they are doing). I would highly recommend Bio-One if you find unwelcome critters have invaded your home, I only regret I did not call Bio-One sooner. Thank you for helping me reclaim my home, Phil!

Arrived next day after calling for an appointment. Courteous. Explained everything they planned on doing. I would definitely.have them return if needed.

Unbelievable kindness! Gentle souls who were compassionate and integral; they worked hard to do the job and ease our stress. It is more than a season of kindness; it is clearly a business that cares about the service they provide and the people they serve … what a rare blessing! Thank you!!!

Bio-One did a deep clean and rodent extraction of our storage facility. They were great! Everything was removed, sanitized, re-arranged and returned to the storage unit. The staff were friendly, set on their jobs, and very helpful. I would recommend to others.
