you shouldnt have any cracks, what size crack? what is the field stone mortared to? is the fireplace brick all the way or did they frame out in metal studs and put up a backer board that the field stones are on?..a picture would help..
We had a wood burning field stone fireplace built at our house in 2013. Last weekend, I noticed some step cracking in the mortar which runs down from about a half a foot above the mantle to the top of the fireplace doors. The cracks seem to follow a path around the field stones. I was wondering if these cracks are normal, or if they will get worse and we will need to have the masonry re-pointed?
Thank you for your help.
