After being told by several contractors that the fireplace was not restorable, Antrim’s made it happen. We opened up the sealed up chimney and lined the cavities with UL listed lifetime warrantied stainless steel liners. We poured a new concrete hearth floor and built a modified Rumford firebox. (We used reclaimed antique brick for the hearth extension.) Upon the owners choice we used a Pennsylvania blue stone for the facing. The mantel is being restored and it should be reinstalled soon.
