We had a few quotes, of which Marsh was not the cheapest, but ultimately matched another quote.
The service was excellent, and the installer who's name I forget (an east coaster), was the most professional guy I think I have met. He had other guys working with him, and I can honestly say I have never heard someone be a better leader than him. He was calm, collected, knew how to direct people and motivate them. I wish my industry had 100 people like this guy.
Overall they did a fantastic job of installing and following up. There was a flaw in the fireplace, that they fixed within the week.
Go with these guys. You will not regret it!
