The chimney "doctor" is, unfortunately, a quack. I say unfortunately because he was seemingly a nice guy. But I don't recommend people based solely on their personality. They must also be competent and the "doctor" was not. We had recently purchased a new home and the home inspector, in front of my eyes, had successfully tested the gas fireplace. When we moved in we found that the fireplace was no longer working. I looked online and found the chimney "doctor." Over the phone and in person, he was a nice guy and seemingly spoke intelligently about our gas fireplace issues.After finishing his inspection he informed us that the coupler (or something) was broken and that we would need to special order a piece. The cost of his inspection was around $200, he estimated the piece to be around $30 and the installation to be another $200. That was not good news to hear, but we didn't feel we had much choice if we wanted our fireplace to be up and running again for the winter. When he left, he informed me that I needed to determine the make and model of the fireplace (using the manual from my neighbor down the street with the same model house) and to give him a call. After getting the make and model I attempted to reach the "doctor" but did not receive a call back. I tried again with the same result. And again with the same result. Frustrated, I gave up. Fortunately, a few weeks later I was shopping with my wife and children downtown San Luis Obispo and walked into Forden's as the kitchen supplies peaked my interest. When I realized they also sold and serviced fireplaces I took a card to schedule an appointment. Not only was the gentleman that came from Forden's nice but he was compitent to boot., Within two minutes he was able to troubleshoot our issue: "Here is the problem. This wire is detached.." Within three minutes he corrected the problem. He spent the next 27 minutes cleaning and touching up some paint inside our fireplace at no additional cost. What a world of difference between the "doctor" and this gentleman. Bottom line, if you need to make a house call for your fireplace issues, don't trust the "doctor".
