How to Repair Porch Columns
Repair or Replace Your Wood Porch Columns the Easy WayKnowing how to repair porch columns (or replace a porch column) can save you lots of money and prevent damage to your porch and home. It is easier than you might think and can be done fairly quickly.
Wood porch columns are susceptible to rot and decay over time. If not repaired or replaced, a structurally deficit porch column may no longer support the porch roof causing extensive damage.
On this page, we share ways to repair your porch columns
Depending on the amount of decay or damage to a wood porch column, you have options ranging from wood restoration products such as liquid wood and epoxy and others to actually replacing part of the column.
Almost anyone with basic carpentry skills can repair a porch post; however, for more extensive repairs, we highly recommend you contact a reputable local contractor.
Repair Porch Columns Using Wood Restoration Kits to Save Time and MoneyWood restoration kits are an excellent way to repair porch columns (and other rotted or decayed wood structures) without removing the column itself. You can even use some of these products for structural repairs too.

How to Repair Porch Columns the Easy WayWe'll show you how to remove and repair a decayed porch column or for replacing one. Depending on your skills, time available, or budget, you might want to consider each option. Sometimes, it is best to just replace the column; the process is the same.
Here's how to repair porch columns that have only minor decay at the bottom.
Cut Nails or Screws Attaching Column to BeamUse a hack saw (or a reciprocating saw) to cut through the nails or screws that attach the column to the beam at the top of the beam.
Raise the BeamUse a jack (we used a car jack) and a 4x4 post or equivalent cut to fit between the jack and the beam. Raise the jack ever so gently as to take the pressure off the column - you don't have to raise it much.
You then should be able to remove the column.
Using jack to lift beam
Mark and CutRemove the bottom plate if applicable (as was the case with our porch column). Mark and cut the column a few inches above the damaged wood.
Mark and cut off bottom of porch column
Replace Rotted SectionsIn this case the bottom of the column and a partial side needed to be repaired. We were able to cut out the damaged section which required us to cut new sections from treated lumber.
We then used construction adhesive and exterior screws to attach the new pieces. Ensure the new pieces are sized appropriately to ensure the column is the same length as the original column.

Attach the Bottom Plate If Applicable
Re-attach bottom plate if applicableIf there was an existing bottom plate, re-attach it to the column.
Install the Repaired Porch ColumnPosition the column, lower the jack, and secure the repaired column to the beam with nails or screws.
