modernizing exterior columns

To properly enclose an existing metal support column, you need to first ensure that the existing column is level and adjust if necessary by tapping on the leveling bolts (usually found under the caps at the bottom).  Next, box the column in by custom cutting plywood (you want only one plywood piece per side).  Screw the plywood in place but, as seen in the final picture below, add construction adhesive and caulking on the corners.  Note that when you place the first piece onto the existing metal column, you need to use self-tapping screws.
