Repairing a Load-Bearing Wall From "DIY to the Rescue" episode DTTR-204

The DIY to the Rescue crew puts safety first -- by adding a new support beam as the first order of the day. The crew gets started by taking out the remainder of the wall, cutting the old joists and adding a new support beam. The beam is installed, then the drywall is taped, mudded, sanded and painted.

Materials:

Reciprocating saw
Drywall saw
Hammer
Chop saw
Wood screws
Tape measure
Drill

For Safety's Sake:

• Always add bracing to support any structural area of a home (figure A) before altering it. Always consult a licensed contractor or architect before removing any part of your home.
  
• Turn off any electrical wiring in the area, and check for plumbing and wiring. Have a licensed electrician move or remove any wiring which may be problem.
  

1. Once the bracing is replaced and any problematic wiring has been removed, take out the drywall and insulation around the area to be replaced. Use a chalk line and reciprocating saw (figure B) to keep your drywall cuts as straight as possible. Tear drywall (figure C) from ceiling and replace insulation that has fallen as needed.

2. Make sure your bracing is still strong before removing any joists or ceiling supports.

3. Build your support beam in advance of removing any support to eliminate the down time between removal and replacement of support. Measure the length of the space to be spanned and allow at least 8" extra for setting on top of supports on each end.

4. For a really strong beam, the Rescue crew used 2" x 8" lumber with a piece of 1/2" plywood sandwiched in between (figure D). Four nails were positioned every twelve inches along the edge of the beam for strength.

5. Next, use a circular saw take out the area where your new beam will fit (figure E). Cut through the joists to allow enough space for the beam.

6. Install new beam. Angle the crown -- or the natural curvature of the boards -- upward to keep the ceiling from bowing. Then, attach the beam to the joists with nails, followed by joist hangers (figure F) for added strength.

7. Once beam is secured, remove bracing before replacing drywall to avoid cracks from shifting.
