We started using Safeguard when our house was built. He was recommended to me by Cathy Maben. Gabriel is very reliable and thorough. He calls a few days before each quarterly treatment is due to scheduled a time and day and he shows up when he says he will. We have been very happy with his service and the fact that I never have to worry about him coming when he says he will is very important to me. If there is a problem in between our regularly scheduled visits he is very responsive.
