Ok, thanks. We service a lot of Gas Appliance Chimneys like yours. How long has it been since you last had the chimney inspected?
They probably will answer never, or chances are they had a very basic inspection at some point. Now we’re going to help them see the importance of an annual NFPA 211 based inspection. We will be doing and inspection and sweep if needed by default. No need to talk about the differences on the phone.
