# How Pier and Beam Leveling Works: A Step-by-Step Guide > Pier and beam leveling restores floor elevation by adjusting or adding piers, shimming beams, and repairing crawl space framing. Canonical: https://foundationrepairlab.com/pier-and-beam-leveling/ Last updated: 2026-11-09 Pier and beam leveling restores floor elevation by adjusting or adding support piers, shimming beams, and repairing or replacing damaged wood in the crawl space. Unlike slab repair, this system sits above the ground with a crawl space underneath, which gives technicians direct access to the framing. The process starts with measurements, not assumptions. ## What a Pier and Beam Foundation Looks Like A pier and beam foundation consists of concrete footings or piers spaced beneath the house, wooden beams resting on those piers, and floor joists spanning between the beams. A crawl space, usually 18 inches to 3 feet high, separates the structure from the soil. Because the wood is accessible, leveling crews can measure deflection directly rather than inferring it from interior cracks. The load path runs from the floor, through the joists, to the beams, then down through the piers to the bearing soil. If one pier settles or a beam rotates, the floor above sags. Leveling reverses that movement by restoring the piers to their original elevation or by adding new support where the original piers have failed. ## Measure First: The Inspection Every leveling job begins with a measurement phase. A technician or structural engineer records floor elevation at multiple points, typically using a laser level or zip level, and maps the high and low spots. Crack width is noted where interior drywall or exterior brick shows stress, using the standard benchmarks: cracks under 1/16 inch are generally cosmetic, while cracks at or above 1/8 inch warrant monitoring. The inspection also identifies the cause of movement. Common culprits include: - Poor drainage under the crawl space - Rotted or termite-damaged beams and joists - Piers that have shifted or sunk into soft bearing soil - Improperly spaced original piers that cannot carry the load An engineer inspection typically costs $400–$1,500 and has a lead time of 1–2 weeks. Permit requirements vary by city and county, with approval typically taking 1–3 weeks. ## How the Leveling Process Works Once measurements are complete, the crew levels the structure in a controlled sequence. Raising a foundation too quickly can crack drywall, damage tile, or stress plumbing lines, so movement is usually limited to small increments over several visits. The standard steps are: 1. **Shore the structure.** Temporary jack posts are placed beneath beams to carry the load while existing piers are adjusted or replaced. 2. **Adjust or replace piers.** Existing concrete or steel piers are raised to the target elevation. If a pier has failed, a new pier is installed adjacent to it. 3. **Shim the beams.** Steel or pressure-treated wood shims are placed between the pier cap and the beam to lock in the new elevation and eliminate gaps. 4. **Repair damaged framing.** Rotted beams, joists, or sill plates are sistered or replaced before the load is transferred back to the piers. 5. **Remove shoring and verify.** Temporary jacks are removed, and final elevations are checked against the initial measurements. The goal is not to make every floor perfectly flat. Older homes rarely achieve perfect flatness, and chasing it can cause new damage. The objective is to stop active movement and bring the structure within an acceptable tolerance. ## Cost Arithmetic for a Typical Job Pier and beam leveling is priced by the scope of work, not by square footage alone. A typical pier job ranges from $6,000 to $30,000. The variables are pier count, depth to bearing soil, accessibility of the crawl space, and the amount of wood repair required. Here is a simplified cost illustration for a mid-sized home: - Eight new piers at $1,000–$3,000 each: $8,000–$24,000 - Beam shimming and minor carpentry: $1,000–$3,000 - Engineer inspection: $400–$1,500 Estimated total: roughly $9,400–$28,500, which falls inside the typical $6,000–$30,000 pier job range. If extensive framing replacement is needed, costs can move toward the higher end or beyond. For comparison, other foundation repair methods carry different price structures. Mudjacking costs $3–$8 per square foot, while poly foam injection runs $5–$15 per square foot. Carbon fiber straps cost $400–$1,200 each, and wall anchors run $500–$1,500 each. These methods apply to slab or basement walls, not to pier and beam crawl spaces, so they are not substitutes for pier leveling. ## When Leveling Is Not Enough Pier and beam leveling works well when the issue is settlement, sagging beams, or deteriorated pier support. It does not fix a foundation that has lost structural integrity across a large portion of the structure. As a general reference point, replacement is often considered when roughly one-third of the foundation has failed, though that threshold depends on an engineer’s evaluation. Repair costs are typically measured as a percentage of structural replacement value. Minor restoration work may run 10–25 percent of structural replacement cost, while major repairs can reach $20,000–$40,000. Full foundation replacement can range from $40,000–$150,000. Leveling sits at the lower end of that spectrum when the crawl space framing is otherwise sound. ## Warranties and Long-Term Expectations Pier installations typically carry a lifetime, transferable warranty. If the home is sold, a transfer fee of $100–$500 may apply. This warranty covers the pier itself against failure, not future movement caused by unrelated issues such as new drainage problems or additional soil settlement elsewhere under the home. Homeowners should also manage moisture in the crawl space after leveling. Standing water or chronic dampness can rot new shims and framing, undoing the structural work. Crawl space encapsulation costs $3–$8 per square foot, or $4,000–$15,000 per job, and may be recommended if the crawl space shows signs of persistent moisture. ## Choosing the Right Contractor Because pier and beam leveling depends on accurate measurement and careful sequencing, the contractor’s process matters more than marketing claims. Ask for a written scope that lists pier count, pier type, depth to bearing, shimming method, and any wood repair. Compare unit prices, not just the total, and confirm whether the engineer inspection and permit handling are included.

Pier and beam leveling is a measurement-driven repair. When the piers are sound and the framing is intact, adjusting elevation and shimming beams can restore stability without replacing the foundation. When the wood or piers are beyond repair, replacement of those components becomes part of the leveling scope.
