Bulwark's has provided great reliable service and a timely response to all of our regular service calls and any additional service requested. Dustin, the Bulwark service tech, has treated my home numerous times and has been good about call ahead if he is running early or running behind. Communication with Bulwark has always been one of their strenght, especially from corporate office. I been with Bulwark for approx. 5 years, and have referred them to a number of my friends. Keep up the good work.
