My initial house treatment was performed by Kelvin. He was on time, courteous, knowledgeable and respectful of my home. Kelvin educated me as he performed his tasks and made sure to keep my entire menagerie of pets safe. I had an entirely positive experience. Incidentally, I used ChemTec in my previous home for 11 years and have always been thoroughly pleased with both the company, as well as the technicians that have come to treat.
