In this video, This Old House general contractor Tom Silva shares tips and techniques for safely hangings framed objects on walls.
How to hang a heavy mirror
- To hang mirror on a plaster wall, use a toggle bolt outfitted with a picture-hanging hook.
- Drill hole through plaster large enough to accept the toggle bolt.
- Thread machine screw through toggle bolt nut, then pinch flat the wings on the toggle and push it through the hole in the wall.
- Tighten the screw with a screwdriver until toggle bolt contacts the back of the wall.
- For drywall, start by weighing the mirror to ensure you don't exceed the capacity of the hanging hardware.
- Mark a short line on the wall to represent the top edge of the mirror.
- Take a 12-inch-long piece of 1x2 and mark a centerline at 6 inches.
- Pull the 1x2 tightly under the hanging wire on the back of the mirror.
- Measure down from the top of the mirror to the top of the 1x2.
- Take the measurement from the previous step and measure down from the short line marked on the wall. Draw a second line to represent the position of the hanging wire.
- Align the center mark on the 1x2 with the second line. Use a torpedo level to align the 1x2 perfectly level.
- Draw short pencil lines along the upper right- and left-hand corners of the 1x2.
- Tap in a hanging hook on each corner mark.
- Hang the mirror on the two hooks.
