We have two gas fireplaces that have not worked in a few years which we hadn't bothered with until the recent bitter cold spell. (When the fireplaces first stopped working about 4 years ago, I had called another provider who specializes in gas fireplaces, and short version of the long story, our fireplaces weren't working again the day after their "repair".) I called Guirkin mid-morning and at first, they said they couldn't get to us until Monday, but then they realized they would have someone in the area for another job and said they would stop by sometime that afternoon. He arrived around 4:15 and quickly got the first fireplace started. He explained the reasons the pilot light may go out, including stating that they do eventually require replacement. He took down the model and serial numbers for both fireplaces to have on record for Guirkin and for us in case we start having problems again and need replacement. (So far both are still working fine. ) The upstairs fireplace had been turned off with the key (which I do not recall us doing, but apparently we had for some reason 4 or more years ago). I couldn't find the key, so he used pliers to turn it back on. Then he messed with the pilot light for several minutes and made some other adjustments, and it was working in about half an hour. He was here for just a little over an hour. He seemed very knowledgeable about gas fireplaces, providing a complete answer for every question I had. He also offered other recommendations, for example, using steel wool around the hole where the gas line comes in to stop some of the draftiness and to keep out mice. Overall, I was very satisfied and will be using Guirkin again in the future, particularly for yearly care and maintenance on our gas fireplaces as well as our heating and cooling systems.
