Fireplace Mantel Surround Measuring Guide
Below are tips for measuring your existing conditions or planning for new construction projects or remodels. Visit FAQ page for even more advise.
Firebox– Measure the height and the width of the firebox. Most fireboxes are rectangular. For masonry or brick fireboxes measure the inside opening. On a pre-fab or a gas firebox measure the areas that you would want exposed. Most pre-fab or prefabricated fireboxes are black and may have vents at the top and the bottom. Those vents need to stay exposed. In remodel situations the new fireplace inner panels should come up to where the old ones were installed. Go to the fireplace quote page to see a diagram. Inner panels that are provided by Stone Fireplaces are typically large so that they can be cut down to size for a perfect fit. Some models can be designed to be installed without the flat inner panels. Most fireplaces are made and installed with inner panels. If you do not want inner panels make sure that you discuss this with our sales representative to see if it is an option with the fireplace design that you want and your firebox size.
Overall Space– Be mindful of the space that your new fireplace mantel will be installed on. Are there any windows or doors that might be in the way. Is there a buildout that the fireplace surround will be installed on. If so what is the size of the buildout. BE aware of where the gas valve or key hole for the gas valve is located. This is often installed on the side of the chimney or firebox but can sometimes be placed in the hearth area. How high do you want the fireplace to be? If you are looking for an overmantel do you want it to go to the ceiling or stop just below. If there is a TV mount or lighting above the mantel shelf it is something that we should be made aware of. It is a good practice to send us a picture of the existing space. This way we can ask for specific measurements if we for see a concern. Those pictures can be emailed or one of our team members can FaceTime or video chat with you. A larger room may require a large fireplace. Be mindful of the overall space when choosing the mantel surround size.
Hearth– The hearth is the large slab that sits on the floor and the that surround legs rest on. The hearth is normally the size of the mantel shelf. Most codes for an open flame require for the depth to be anywhere from 18″ to 20″. An open flame is an exposed flame. If there is permanent glass in your prefabricated firebox this can sometimes allow for a smaller depth depending on your local city code. Almost all masonry/brick fireplaces are exposed flames and would require an appropriate hearth. The hearth can sit on top of the existing flooring or be dropped in flush with the floor. It can also sit a little depressed into the floor. These are all options that are usually open in new construction projects. For remodels you can place the hearth the same way it was before to not have to make flooring changes. On wood flooring, tile or carpeting a quarter round can be added around the hearth to finish into the floor. This is not necessary but is an available option.
