How to Install Decorative Wood Beams

Decorative (faux) wood beams can add a rustic look to a cathedral ceiling. The lightweight beams are easy to install and don't add any structural load to the ceiling. Most are made of polyurethane and wood laminate or a stainable composite. Read on to learn how to install decorative wood beams.

Things You'll Need

• Faux wood beams
• Box of 4-inch by 3/16 toggle bolts
• Angle finder
• Chalk line
• Cordless drill with magnetic screw tip
• Drill bits
• Hand saw
• Measuring tape
• Pencil
• Miter box

Instructions

1. Measure your ceiling space and order the beams. When the beams arrive, set up your scaffolding or ladders to mark the ceiling. Rented scaffolding is the safest alternative.

2. Calculate and write down the angles at each end of the ceiling slope using the angle finder.

3. Mark the locations for multiple beams by snapping a chalk line on the ceiling for each beam's location. Mark the ceiling for the center of the beams after measuring the length of each one.

4. Install mounting blocks every 24 to 36 inches along the chalk line. Blocks should be mounted to ceiling joists whenever possible. Use 4-inch toggle bolts if there are no ceiling joists. Mounting blocks need to fit the interior dimension of the beam.

5. Cut the top end of the beam to the angle you measured earlier, measuring from the center mark you made. Then cut the bottom angle as well.

6. Place the beam over your mounting blocks. Make sure the beam is pushed up tight to the ceiling, then use 2-inch drywall screws to mount the beam to the blocks. You should have someone holding up the opposite end of the beam.

7. Fill the screw holes with color-matched wood filler.
