We had Mark R. out to our house to take a look at the gas fireplace in the basement. It runs off of a remote which takes 9-V batteries and ours was dead, so he ran to a hardware store nearby to pick some up. He also took the time to show me how to disassemble to fireplace and replace the AA batteries for the receiver, which was the underlying issue, so I can check it myself next year. Mark R. was polite and friendly the entire time and wore a mask both in and outside of our house. He made sure I had all of the information I needed and gave me a few tips for our specific model of fireplace. The company as a whole was very communicative and flexible as well. We'll definitely be using Chimney pros from here on out. Thanks, Mark!
