Tips For Installing Wood Beams on a Ceiling

January 2, 2020

Decorative beams can transform a ceiling and a room, adding warmth, character, and ambiance to the home decor of the space. Vaulted ceilings look particularly stunning with the addition of wood beams and help improve the look of the large, blank canvas. 

In most instances, ceiling beams are not used for support and can be installed by the homeowner. This is particularly true for faux wood ceiling beams. Faux wood beams look just like the real thing, since they are still made out of real wood, but are made up of three or four pieces to create an empty “box” on the ceiling. These faux ceiling beams are much lighter and are able to conceal wires or pipes.

Gather Materials

Regardless of whether you are installing antique ceiling beams or faux ceiling beams, you will need to make sure that you have the right tools on hand for the job:

  • Measuring tape

  • Circular or miter saw

  • Chalk line

  • Tape measure
  • Wood glue

  • Ladder or scaffolding

  • 2×4 “nailers”

  • Finish nails

  • Hammer or nail gun

  • Stud finder
  • Brackets

Real wood beams need to acclimate to the temperature and relative humidity of the room where they will be installed in order to get the best results. This means making sure that the room has a consistent temperature and humidity level for 6 – 7 days leading up to the installation. The beams should be left in the room they will be installed in for roughly 72 hours prior to installation to give them a chance to acclimate properly.

In addition to making sure that the beams are ready, you should also make sure that your ceiling is able to support the beams. Check for ceiling studs or add a frame if necessary. Measure the ceiling and create the desired pattern for the beams.

If you are installing faux wood beams, they will need to be assembled prior to installing them on the ceiling:

  1. Identify the different pieces of the beams; they should be labeled for easy assembly.

  2. Measure and mark any pieces that will need to be cut to fit the ceiling.

  3. Make cuts on a circular or miter saw, and double-check that all pieces that will make up a beam have been cut to the same size.
  4. Place the first piece of wood on your assembly table and run a bead of wood glue along the edge where it will interlock with the next piece.
  5. Insert the next piece (or pieces) and make sure that they fit snugly into their joints.

  6. Wipe away any excess glue that may have come out of the joints.

  7. If desired, use finish nails to secure the pieces of the box beam to one another.

  8. Repeat for the remaining beams.

  9. Leave enough time for the glue to dry before you begin installation.

Once you have the beams ready, take the time to prepare the ceiling:

  1. Measure and mark the ceiling where you intend to install the beams.

  2. Stretch a chalk line across the ceiling and snap it to keep lines even and to mark the necessary grids.

  3. Install “nailers” on the ceiling to make installing the faux wood beams easier. Nailers are thin strips of wood that the beam will fit over snugly. They’re easily nailed to the ceiling joists, and will allow you to install the diy faux beam over them securely, without needing to use bolts. Follow the pattern you marked out to attach the nailers to the ceiling.
  4. Install the faux ceiling beams by sliding them over the nailers, and securing them temporarily with a bracket.
  5. Nail the edges of the faux wood beams directly into the nailers to secure them, and remove the brackets.

Tips for Better Installation

Always test any sandpaper, wire brushing, or other cuts or materials on an unseen area to test its appearance.

Never directly attach the beams to drywall or ceiling plaster; always make sure there is a joist that can support the beam.

Make sure you can safely lift and support the beams while they are being nailed into place. Use help as needed.

Enlist the help of a professional for solid wood beams, which will require the use of lag bolts and potentially additional ceiling support to install.
