Hello! My husband and I just purchased an 11yo house that has a 14X17' vaulted room off the back. It has a poor quality gas fireplace in it, but we desperately want to put ] brick hearth fireplace in its place. Did we mention we are wood purists? There is crawl space under the room, and two small windows above the mantel - we are getting prices all over the place. We live in Loudoun County, VA, and would love to hear from some wise, knowledgeable men who could tell us more about it - maybe even some that are in our area! Any estimates? I know that can be hard to do...
