    decontamination and biohazard cleaning services reviews
    Megan Harbuck, Exton, 2/1/2025
    Working with Tom and Bio-One of Chester County has been an absolute pleasure. Tom, the owner, has explained to me how their services work in great detail, in a way I can easily understand. The team is full of reliable people who get the job done right in an efficient manner. I can't recommend them enough.

    If I could give them 10 stars, I would. I can’t say enough about the efficiency and professionalism of everyone from the owner to the foreman to the work crew. Very respectful on every level and finished the job ahead of schedule. Highly recommended.

    Had Bio-One clean up at a friend's house. They are a very pleasant crew to work with and very thorough. Very prompt also. Was there within 24 hrs for the cleanup. I will highly recommend them. Tom the owner took his time to explain everything about the job from start to finish.
