    Bio-one NW helped me greatly during a period of hospitalization. Sean and his team were thorough in their questions, and explanations, and that thoroughness and attention to detail carried over into the work that they did. I felt safe coming home knowing that I was going into a clean environment to recover. Thank you Bio-One NW Team!

    I want to give a huge shout out to the Bio-One team for the amazing job they did for a family member’s basement. To give you an idea of the horrific state of the basement, let me say two words…. Hoarder and Rats. After getting Pest Control in to eradicate the rats, I called Bio-One to see what they could do to help. Sean was amazing at getting a team out to the house and reassuring me that they could take care of everything. Because of the magnitude of the items to be removed and the clean up afterwards, Sean sent out a team of four. These guys are incredible. I can’t say enough about Jason, Travis, Joe and Jaz. These guys worked hard, quickly and efficiently and even though this was really nasty, heavy, and hard work, I never saw anyone slacking. Everyone, from Sean in the office to the guys in the field (Jason, Travis, Joe and Jaz) were professional, kind and courteous. Just as Sean promised, they took care of everything, from getting rid of all the items from 60 years of hoarding, cleaning/vacuuming up EVERYTHING, and disinfecting the entire basement from top to bottom. I am so appreciative of all they did, and I would give them more than 5 stars if possible.
