I recently hired Bio-One of South Sound for remediation service on a long-overdue garage clean-up and to address a mouse infestation, and I couldn't be happier with the results! From the moment they arrived, Tim and his team were professional, knowledgeable, and attentive. They conducted a thorough assessment of the space and developed a clear plan tailored to my needs. Their attention to detail in organizing and decluttering was impressive; they transformed my chaotic garage into a clean and functional storage area. As for the mouse infestation, they tackled the problem with expertise. They vacuumed up the nest and droppings, disinfected contaminated items and surfaces, and took the time to educate me on preventative measures to keep my garage critter-free in the future. The entire process was seamless, and the team worked efficiently without cutting corners. I truly appreciate their dedication to quality and customer satisfaction. If you're facing a similar issue, I highly recommend their services!

My grandma and I recently hired Bio-One to help us clear out some rooms we were overwhelmed by. This is something we've put off for a while out of embarrassment but making the choice to reach out and get help from Bio-One and the people who work there was worth letting others see our embarrassment. Jillian, Ian and Tim were all absolutely wonderful to work with and were all incredibly understanding and kind throughout a very emotional process. The help they've given us has been genuinely life changing, words cannot express how grateful we are and how amazing everyone was through the whole process.

When you read this review, don't think of it as a normal review, that people casually post. Please view this as a heartfelt thank you and as true and honest endorsement for Tim, Bio-One, and his team. We are truly grateful for the top notch service that Tim and his team provided for us in our time of need. Not only did he call us back right away, he squeezed time into his already busy schedule to take a look at the job and give full assessment with a fair and accurate quoted price. Once we agreed to move forward with the quoted service, it was scheduled and taken care of without any issues the next day. You are probably thinking at this point that this sounds pretty standard. Well let me assure you it was not by any means standard. At every interaction Tim, Bio-One, and his team went far above and beyond at each step. On top of that, the caring, compassion, and true field experience really shines through in all that they do. You can really tell that they are here to help you, truly care, view you as a customer yes, but more than that, as a human and not a number or just another job. Honestly I could go on and on but I think you get the point. For all of these reasons we will never use any other company than BIO-ONE, and give the highest of thanks and praises from our family to their family. :) If anyone needs a reference I would be happy to provide it, please reach out. Until then don't trust anyone but BIO-ONE! Thank you Tim and the Bio-One Team!
