We switched to Bulwark from another company and couldn't be happier. I was having an ant issue and called after hours and left a message. To my total shock I got a call back from Seth who set up an appointment for a technician to come out the very next morning. Our technician Stephen wasn't just on time he was early! He addressed the problem that I had and even went above and beyond and treated some other areas as a preventative measure. Wonderful customer service and their product works!
