Bowdens did a great job on our fireplace.
The only reason that I give it 4 stars instead of 5, is that they were a little slow during the install process. They seem to have a busy schedule, so that is a good sign that they do great work. Some of the delay may also be due to our incompetent Township building office, but would have appreciated if the installer stayed on top of it a little better as the paperwork could have stated clearer that we already had gas run to the fireplace and inspected.
We had a Mendota unit installed and have been very happy with its performance this cold winter. The install went great. One piece on the inside surround had a small defect and Bowdens dealt with it right away and got me a replacement.
Overall would highly recommend Bowdens. Make sure you give sufficient time for the install process.
