Pier and Beam Foundation Repair Cost in McKinney, TX

Pier and beam foundation repair cost McKinney homeowners face is priced by the piece rather than by the wall. A pier and beam house sits on wood beams that rest on concrete or masonry piers, with floor joists spanning between the beams and a crawl space underneath, so a repair is a list of shims, joists, beams and piers rather than a single pier count. Modernize’s 2026 pier and beam guide puts the typical range at $3,000 to $9,500 with a $6,500 average, and Fixr’s 2026 guide runs $2,000 to $15,000. This page explains each line item, what moves a McKinney job up or down, and how to read the estimate. The crawl space inspection through this site is free and the estimate is written, so call (972) 555-0100 when floors start to bounce.

What pier and beam repair costs nationally

Modernize publishes a dedicated pier and beam guide. Its 2026 figures run $3,000 to $9,500 for a typical job, with minor reshimming from $1,000 and major structural work above $10,000. It also sorts jobs by severity: minor at $1,000 to $3,500, moderate at $3,000 to $8,000, and severe at $8,000 to $15,000 and up.

Fixr’s 2026 foundation repair guide gives $2,000 to $15,000 for pier and beam homes, and Modernize’s main foundation guide gives $2,500 to $8,000 for the same category. The disagreement is at the top. Fixr’s $15,000 covers full underpinning with many new piers, while Modernize caps the typical range at $9,500 and treats major structural work as its own tier.

Every row names its guide, and a free written estimate replaces those ranges with a count for your crawl space.

What changes the pier and beam foundation repair cost McKinney homeowners pay

Start with the soil. The USDA Natural Resources Conservation Service describes the Houston Black series, the Texas state soil, as 40 to 60 percent clay with high shrink-swell potential, opening cracks 1/2 to 4 inches wide at 12 inches deep in dry periods. A pier and beam pier is a short concrete or masonry post bearing on that clay, so when a drought shrinks it, the pier settles and the beam above it drops. The NRCS fact sheet adds that the clay takes water rapidly when it is dry and cracked, which is why the first wet fall after a drought heaves the piers back unevenly.

Housing age matters, because most pier and beam homes in McKinney are older. Dustin Pitts Realty describes homes around the historic downtown square as dating to the late 1800s and early 1900s, with Victorian, Craftsman and bungalow styles common near downtown. Those are the pier and beam houses, and their beams and joists have been through every wet and dry cycle in the National Weather Service record, from 25.88 inches at DFW Airport in 2011 to 62.61 inches in 2015.

The count of piers needing shims or replacement is the multiplier. Rot is the wild card: a crawl space that has stayed damp can rot beams and joists that looked fine from the living room, and each one is its own line. Access height under the house changes labor, because a crew working in 18 inches of clearance moves slower than one in 3 feet.

Paperwork is fixed. The City of McKinney requires a permit for any foundation leveling, pier or footing replacement, shimming, or floor system replacement on pier and beam foundations, and the application must include an engineer’s letter and drawings of the affected areas. The permit closes only after the engineer’s final report is uploaded.

Cost by repair type: shimming, sistering, beams and piers

Shimming is the first and cheapest line. A shim is a thin steel or hardwood wedge slid between the top of a pier and the beam it carries. Adding or replacing shims brings the beam, and the floor above it, back to level without touching the pier. Modernize’s 2026 guide prices reshimming at $1,000 to $3,500 per job, and it is often the whole repair on a house whose piers have not settled far.

Sistering joists is the second line. A joist is one of the boards that span between beams and carry the subfloor. When a joist has sagged, cracked or rotted at one end, a new joist is bolted alongside it so the pair carries the load together. Modernize prices floor joist replacement at $350 to $1,000 per joist, and sistering sits in that same range because the labor is similar.

Replacing beams is the third line. A beam carries several joists, so a rotted beam means a section of floor is unsupported. The crew jacks the floor, cuts out the bad beam, sets a new treated beam on the piers and reshims it. Modernize prices beam replacement at $400 to $1,200 per beam, and HomeAdvisor’s 2026 guide prices the job at $1,500 to $5,000.

Adding or replacing piers is the fourth line and the largest. When a pier has settled or crumbled, or a beam is spanning too far between piers, new piers are set under it. Modernize prices pier replacement on a pier and beam home at $2,500 to $6,000 per pier, and new steel or concrete piers driven to stable soil run $1,000 to $3,000 each in all four 2026 guides. See pier and beam foundation repair for how the four fit together, and house leveling when the whole floor has to come back up.

Moisture, drainage and the crawl space

Damp crawl spaces are what turn a shim job into a beam job. Standing water and a bare-dirt floor keep wood wet. Drainage and a vapor barrier, which is a heavy plastic sheet laid over the crawl space floor to stop ground moisture rising into the wood, are the usual add-ons. HomeAdvisor’s 2026 guide prices vapor barrier replacement at $1,000 to $3,000 and a crawl space drainage system at $1,500 to $15,000 depending on scope. See crawl space repair for those line items.

How to read a pier and beam estimate

A comparable estimate lists each of these separately:

• Number of piers to be reshimmed, with a crawl space diagram
• Number of piers to be replaced or added, with the per-pier price
• Each joist to be sistered or replaced, and each beam to be replaced, as its own line
• The lift and re-leveling of the floor, and whether it is included in the pier price
• The engineer’s report and the McKinney permit fee
• A plumbing check of drain lines under the house before and after the lift
• Vapor barrier, drainage or dehumidifier work if recommended
• A contingency for rot found once the crew is under the house
• The warranty terms, attached, and the payment schedule

Compare estimates by the count of piers, joists and beams, not by the total. If one contractor found rot and another did not, ask both to show you the wood.
