I bought a fireplace insert several years ago and they did an excellent job. But a few days ago, I found a piece of aluminum in the yard that appeared to be a chimney cap. So I took it in and showed it to Mike. He immediately recognized that it was not one of his but due to the fact that I cannot easily get on my roof, I asked him if he would come out and take a look to see if it may have come from my furnace pipe. He did so the very next day! He told me everything looked good up there and when I tried to pay him for his time, he refused! That’s going the extra mile in customer service! I highly recommend this company for quality of products, installation, and service after the sale.
