Determine the Damage
For posts in direct contact with the floor, probe with a screwdriver to determine if there’s any rot. If it’s not rotting, then the concrete footing is likely sinking or deteriorating. You will have to saw through the floor to get to the footing.
Consult With Professionals
A lot of factors play into the structural integrity of your home, and if you’re like most people, then you’re likely not an expert in structural engineering. For issues related to the structural integrity of your home you should always contact the pros first.
Raise the Beam
After consulting with the professionals, acquiring any necessary building permits, and hiring help for the project, the load-bearing beam can be lifted to repair the post and/or footing. But before you raise the beam, make sure to release any lines connected to the beams in the basement—i.e.
Install Concrete Footings & Plinths
For undersized footing, you will have to excavate, remove the old footing, install steel reinforcing rods, and pour fresh concrete. If you plan to install a plinth block as well, place it on the wet concrete footing once the concrete can support the block’s weight.
Step 1
Use a level against the bottom of the beam supported by the old post. Check the indicator; if the bubble is in the center, make your new post the same length as the old; if not, tip the level away at one end until the bubble is centered.
Step 2
Measure the distance from the end of the level you tipped away back to the beam. Divide the length of the level into the length of the beam to calculate the distance the beam has settled.
Step 3
Choose a replacement post, equal to or stronger than the original. Measure the height of the original post and measure and mark the new post for cutting, plus any settling you are going to correct. Make the cut on a miter saw for a square end.
Step 4
Set two post jacks one on either side of the damaged post. Cut 4-by-4 posts to length, 3/4-inch shorter than the space from the top of the lowered jacks to the bottom of the beam above the post you are replacing. Position one post in the bracket on the top of each jack.
Step 5
Raise each jack a little at a time, going from jack to jack to maintain a level lift. Watch for a separation to occur at the top or bottom of the original post and stop lifting at that point.
Step 1
Use a sledge hammer to tap the old post out of position. Raise the jacks if needed to account for settling. If it is more than 1/2 inch, raise the jacks 1/8 inch at a time and allow the beam to rest between raises for one hour.
Step 2
Watch for signs of other damage on each rise. Get professional assistance if the beam pulls away, or significant cracking takes place.
