Donald H., our tech, called before arriving and showed up right on time. He was very knowledgeable and explained everything he was doing to get rid of our pests. He took the time to explain the process and the every two month service but did not try and do a hard sell. I This is my first time using Bulwark and I plan to use them again as long as I can et Donald as our tech. FYI: I chose this company and bought the service as a member of Angie's list.
