How to Support a 32-Foot Sagging Wood Beam
Remove all furnishings, storage or miscellaneous items from the floor that the sagging beam supports. If the beam supports a roof, remove snow and any unattached items on the roof to reduce as much weight from the beam as possible.
Use the tape measure to mark locations recommended by the structural engineer to install adjustable steel columns to support the sagging beam.
Move the adjustable steel columns to their recommended locations. Hand-tighten the top support plate to gently hold the column in place. Use a level to straighten each column to a perpendicular position.
Nail each adjustable column's base and top plates in place. The structural engineer's recommendations will include the number and length of nails and horizontal bracing, if required.
Tighten and raise each adjustable top plate as recommended by the structural engineer. Do not reduce the depth of the beam's sag, or attempt to level the floor, without specific instructions from the engineer.
Replace items removed from the floor or roof above the beam prior to installation of the columns.
