Eric Burch, was very kind and polite as a service tech, July, 11- 13th he came in service my house upon request and my back yard. He also concerns for any another issues that we might have. But all in all he did a fantastic job in providing he services and concerns for the client. I also want to add that Bulwark concern to come and service was exceeds that of most other vendors here in Las Vegas. I just wish there were more people like your service tech in N. Las Vegas ! Thank you, Sincerely Michael A. Perry PS. I would rate this service as a five star service, and I would also like to request him back as my service tech..
