How to Replace Wooden Columns

Removing the Old Column

• 1

  Position post jacks on either side of the column. Measure up from the top of the jacks to the overhead beam. Cut 4-inch by 4-inch posts to fit, with 2 inches to spare. Cut one 11 1/2-inch long piece of 2-inch by 12-inch lumber to cushion the top of each post. Set one post into the bracket on each post jack, with a 2-inch by 12-inch piece on top.

• 2

  Raise the jacks until the posts are snug. Alternate between each jack, raising them one turn at a time until the beam is supported by the temporary posts. Use a pry bar to remove any trim around the top of the column to expose the joint. Cut any fasteners holding the top of the column in place with a reciprocating saw.

• 3

  Tap out the base of the column from under the beam with a sledge hammer until the top of the column is clear. Tip the column over and remove it from the work area.

Installing the New Column

• 4

  Measure and cut the new column to fit from the bottom, if needed. Use a handsaw for a smooth cut. Attach any brackets or hardware required to install your column, at the top and bottom. Fit the trim rings onto the capitol (top) and base (bottom) and slide the column into place.

• 5

  Place a level on each side of the column and adjust the leveling feet in its base with a wrench. If levelers are not available, use shims to adjust the column until it is plumb. Lower the jacks slowly, allowing the weight to settle onto the new column, inspecting it for signs of weakness or other problems.

• 6

  Remove the posts and jacks from under the beam after the weight is solidly on the new column. Attach the hardware in the base or capitol as required for your make and model of column. In general, use the supplied or recommended fasteners and install as many as are recommended, following the manufacturer's instructions.
