FireRock pre-engineered masonry fireplace and chimney systems are unique in that they are easily installed, even by a novice. They go up in about half the time as an all masonry fireplace and eliminate all backup material therefore lowering cost of both labor and material. Being a brick mason by trade and having built several all masonry fireplaces, I would highly recommend installing a FireRock fireplace in place of an all masonry fireplace for both the ease of installation and efficiency.
