    What our clients say

    decontamination and biohazard cleaning services reviews
    Ruth Walker, Washington, 1/1/2025
    Bio-One did an excellent job cleaning up my in-laws apartment after a death. They are very Nic people who helped the family at a difficult time when they didn't know where to turn. The in-laws had been hoarding and hiding it from us - we couldn't even move in the unit. Bio-One cleaned out all the trash and disinfected so that we could have an estate sale for the rest. The customer should be sure to take before and after photos of the affected areas if you plan to file an insurance claim as your insurance company will want a full explanation of what was done.

    The team, with Jermaine as our point of contact, was able to help our building with a sensitive and often surprising situation. They rolled with the changes that came up and delivered professional and attentive service, keeping us up to date on the day to day operations and being willing to work through tricky scenarios. Jermaine was quick to pick up the phone and addresses everything with courtesy and patience. Thank you!
