"Words cannot fully express how grateful I am to have found Biotek Environmental! Ted took a lot of time compassionately listening to my concerns and explaining the initial process over the phone. Tyler patiently shared his extensive knowledge on how mold develops along with natural ways to clean clothes and surfaces. He also explained the meter reads of mold counts and humidity levels as I tagged along from room to room during the home inspection. Every step of the process was clearly explained creating a great sense of confidence in me and Dad. Crew members Jermaine, Ray, and Matt were friendly, considerate, and diligent in their hardworking task of removing the mold source. Donna was very professional and prompt to respond to any questions by email. I could go on and on with how pleased and relieved I am to have found Tyler and company but I will just close by stating the obvious: health is vital. My elderly father's health and general quality of life have improved substantially since we hired Biotek Environmental. They are also a clean company with a generous warranty. I highly recommend them to anyone in need of a healthier home."
