I have a all brick from wall to wall fireplace, the brick stops at the mantle which goes wall to wall. The hearth is raised 15inches or so and is from wall to wall. It looks like a dark hole at the end of the room. We have mirors and shelves above the mantle. I want to change it possibly remove the sides of the firepace hearth and brick. I thought stocco would be good What are your suggestions?
