Ceiling tiles are thin, light sheets of tile that are typically made out of either wood or thin metal. The tiles are typically glued to a clean ceiling or nailed up to cover a popcorn ceiling. Because the tiles are so light, there is no need for added structural support. Ceiling tiles can be removed and replaced when done with care.
Recessed lights, which are installed into the space between the ceiling and the roof, are heavy and can do damage to the ceiling if not properly supported. They have two components: a recessed can light, where all of the electrical components reside, and the trim ring, which is the visible and adjustable portion.
Determine where each recessed light will sit and mark the position. Ideal positioning should be between two ceiling joists. You may locate the joists with a stud finder. Remove the tiles around the area and cut out the drywall using a handsaw. Wear eye protection and a face mask in case the ceiling is insulated. You’ll want a large enough drywall square removed to allow you access to the ceiling joists.
Position a recessed lighting support bar between two joists, drilling wood screws through the support bar and into the joists. The support bar is strong enough to hold the light. Set the can into the support bar’s hole and secure the can in place using bolts and nuts. Attach the electrical components and the light is installed.
Trace the shape of the can onto the drywall and cut out the shape with a keyhole saw. Run a wooden slat between the joists and level with the drywall, securing each side. Reinstall your drywall square, screwing into the wood slat with drywall screws. Patch the drywall with putty. Trace the can’s shape onto the tile and cut it out using a utility knife and reinstall the tile, either gluing or nailing it to the drywall in accordance with the tile manufacturer’s directions. Install the trim ring and enjoy your new light.
