The owners, Brent and Mandy, are fabulous! They came out to give me an estimate in person after most people would have stopped working for the day, gave me a prompt and reasonable estimate, worked hard and did a great job, I'm very satisfied and highly recommend their services!

I have hired other companies in the past to spray and disinfect our office and Bio-One of Dallas County is by far the best. Brent and Mandy Grigsby are really focus on providing great customer service. They use EPA approved surface-active agent, they are friendly and the team showed up with proper PPE. I definitely recommend them.

Bio-One of Dallas County first listened to my situation then the ball was rolling. Not only was Mandy kind, friendly and understanding she and her co-owner husband were both compassionate and considerate. If our world had more people like the good people at Bio-One of Dallas County it would truly be a better world. The job Bio-One of Dallas County did was stellar,they were efficient, extremely professional, honest and extremely kind. I'll be forever grateful to these people.

Brent & maggie cleaned things that I thought were impossible to be cleaned. I called several similar businesses and this was by far the best priced with way more work involved than other companies. They're very friendly & respectful of the property. I felt comfortable that they would get the job done and that's exactly what they did.
Roberta Ford
Very professional company and very compassionate toward their clients. Would definitely recommend Bio-one to anyone who needs these services
