How much does floor pier repairs cost?

The cost of floor pier repairs depends on how many piers have lost contact with the bearers above them, and how far the floor has dropped.

A single pier that's sunk 15mm is a different job to a subfloor where 12 piers have dropped and the floor slopes 40mm from one end to the other. The number of injection points, the volume of resin, and the monitoring time all drive the price.

Here's what catches most homeowners off guard when pricing floor pier repairs: the piers themselves are usually fine. They haven't cracked or rotted. They're sitting on ground that's moved. If your floors are sloping or bouncy, that's a sign of sinking floor piers — and floor pier repairs fix the ground, not the pier. Restumping can run $25,000 to $35,000 and takes weeks. The piers weren't the problem in the first place.
