What is the difference between a pre-fab fireplace and a masonry fireplace?

Click here to see our selection of fireplace doors.

Pre-fab fireplaces are installed on site from components made in a factory, while a masonry chimney is constructed on site by brick masons. The easiest way to tell is by the outside of the chimney. It is most likely a pre-fab if it is covered in wood or vinyl siding like the house. Instead of a brick chimney a pre-fab chimney has a metal pipe flue to vent smoke out of house. Pre-fabs are smaller and some have blowers built in. All pre-fab fireplaces are UL listed. The pre-fab chimney is encased in a wood chase covered by a metal cap to prevent water and provided with termination cap on top.

A masonry or brick chimney is built on site using brick and terra cotta tile for liners and is more expensive to build to maintain. Most masonry chimneys do not have chimney caps installed allowing water and animals to get inside the structure and sometimes inside your house.

Special Note: Pre-fab fireplaces are not any more or less safe than masonry fireplaces. They are just different. Either will help keep you warm and they are romantic!
