To attach a mantel to a brick fireplace, you can use a "slide-over-bolts" or a "cleat" method. For the slide-over-bolts method, drill holes into the brick, insert rods or bolts, and then slide the mantel onto them. For the cleat method, you attach a wooden cleat to the brick first, and then fasten the mantel to the cleat.
Method 1: Slide-over-bolts
This video demonstrates how to install a fireplace mantel on brick:
- Mark and drill holes in the brick: Use a masonry drill bit to drill holes at your desired mantel height. For a strong hold, drill into solid brick or mortar lines, avoiding transitions between materials. You can use a template board with pilot holes to ensure proper alignment.
- Insert rods or bolts: Apply a masonry-safe adhesive like construction adhesive into each hole and insert steel rods, dowels, or lag bolts into the holes. If using rods, some shims may be needed to secure them if the holes are loose.
- Prepare the mantel: Drill corresponding holes into the back of the mantel to accommodate the rods or bolts.
- Attach the mantel: Slide the mantel onto the rods, and for extra security, you can apply a thin bead of construction adhesive to the back edge before sliding it into place. Use temporary supports to hold the mantel while the adhesive cures.
Method 2: Cleat
- Create a cleat: Construct a wooden cleat, such as a 2x4, that is level and centered with the fireplace.
- Attach the cleat to the brick: Mark and drill pilot holes in the cleat and the brick. Use a hammer drill and a masonry bit, then insert anchors like expansion anchors into the brick. Secure the cleat to the anchors with a lag bolt.
- Attach the mantel: Attach the mantel to the cleat using brass screws or other appropriate fasteners, ensuring the mantel is level and secure.
