Pier and Beam
Repair
in Maryland

A pier and beam foundation supports the house on a series of individual piers, brick, block, or concrete, spaced beneath the structure, with wood beams spanning between them to carry the floor framing above. A standard crawl space home, by contrast, typically rests on a continuous perimeter foundation wall, with the crawl space simply being the ventilated area beneath the floor. Pier and beam construction is its own foundation system, common in older Maryland homes, farmhouses, and additions built before continuous foundation walls became standard practice.

You likely have a pier and beam foundation if, looking into your crawl space, you see individual masonry or concrete columns supporting wood beams rather than a continuous concrete or block wall around the full perimeter. An OBW inspector can confirm the construction type during a free inspection.

No, and the distinction matters. Crawl space jacks, our permanent Smart Jacks or temporary adjustable posts, are support posts added beneath an existing beam to correct sag or add support at a specific point. Crawl space structural repair covers general joist sistering and beam work anywhere in the crawl space. Pier and beam repair is specific to the piers themselves, the masonry or concrete columns the whole foundation system rests on, and the beams that sit directly on top of them.

The three connect in a specific way: a failed pier is often repaired using the same techniques as a crawl space jack (a new support post takes the load while the old pier is rebuilt or replaced), and beam damage on a pier and beam foundation is repaired the same way beam damage is repaired anywhere else. But pier and beam repair as a service is about diagnosing and fixing the foundation system itself, piers, pier footings, and the beams they carry, not just adding a post under a sagging beam.

Individual piers settle unevenly when the soil beneath one column consolidates more than its neighbors, tilting the beam it supports and creating a localized low spot in the floor above. Masonry piers can crack, spall, or crumble with age and moisture exposure, especially in Maryland's freeze thaw cycles. Beams resting directly on piers can develop rot where they contact masonry that's held moisture, and undersized or widely spaced piers from original construction may simply be inadequate for the load they're carrying today.

Because piers work largely independently of one another, a pier and beam foundation often shows localized problems, one section of floor sagging or bouncing while the rest of the house is level, rather than the uniform settlement patterns seen in a continuous foundation wall.
