Luke was very polite and knowledgeable about my fireplace and did an excellent cleaning of my fireplace. My original appointment was yesterday between 10:00-1:00, I called office yesterday after 1:00 since no tech arrived yet and was told tech would arrive by 4:00. Luke called me close to 4:00 and we agreed upon an appointment for today at 8:00. Yesterday I spent entire day waiting at my house from 10:00 to 4:00. This was not the fault of Luke who did an excellent job but rather due to overbooking, from what I was told when I called your office after 1:00 yesterday.
