Foundation Repair Cost in McKinney, TX

Foundation repair cost McKinney homeowners should plan for depends on one number more than any other: how many piers the engineer calls for. Nationally, Fixr’s 2026 foundation repair guide puts the typical range at $2,200 to $8,200 with a $5,200 average, and HomeAdvisor’s 2026 guide puts it at $2,225 to $8,133. Those are national figures covering everything from a sealed crack to a full wall of piers. This page breaks them into line items, explains what pushes a McKinney job toward either end, and shows how to read an estimate. The on-site inspection through this site is free and the estimate is written. Call (972) 555-0100 to schedule one.

What foundation repair costs nationally

Four guides agree closely on the middle. Fixr’s 2026 guide says $2,200 to $8,200, HomeAdvisor’s 2026 guide says $2,225 to $8,133, This Old House’s 2026 guide says $2,224 to $8,134, and Modernize’s 2026 guide says $2,200 to $8,400. All four put the national average near $5,000 to $5,200.

They disagree at the edges. HomeAdvisor’s floor is $500 and its ceiling $16,000. Modernize starts minimal crack repairs at $300 and says major repairs run past $35,000. Fixr prices by area at $1.50 to $12 per square foot. HomeAdvisor and This Old House publish nearly identical figures, which suggests a shared dataset, so treat them as one opinion rather than two.

Every row in that table names its guide, and your written estimate replaces those ranges with numbers for your house.

What changes the foundation repair cost McKinney homeowners pay

The soil sets the stage. 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. Its fact sheet notes that in metropolitan areas this shrink-swell behavior is commonly a limitation for building site development. How far a slab edge drops in a dry summer decides how much of the wall needs piers.

Pier count is the multiplier. Fixr, HomeAdvisor, This Old House and Modernize all put a pier at $1,000 to $3,000 in their 2026 guides, and piers are typically spaced 6 to 8 feet along the affected perimeter. A 40-foot wall that has dropped needs five to seven piers. Pier type moves the per-pier figure: Modernize places pressed concrete piers near $1,000, steel push piers near $2,000 and helical piers near $3,000.

Access matters. Perimeter piers go in from outside through small excavations. Interior piers, under a hallway or kitchen, require tunneling under the slab or cutting through it, and Fixr lists concrete removal and landscaping among its cost drivers for that reason.

Paperwork is a real line. The City of McKinney requires a permit for any foundation leveling or pier work, and the application must include an engineer’s letter and drawings showing the affected areas and whether plumbing will need testing. The permit closes only after the engineer’s final report is uploaded to the city’s portal. This Old House’s 2026 guide puts a structural engineer inspection at $300 to $1,000, and Fixr puts permits at $75 to $150.

Housing age plays in. The US Census Bureau reports that half of McKinney’s homes were built in 2007 or later, so many slabs are meeting their first serious droughts now. The National Weather Service recorded just 29.31 inches at DFW Airport in 2023 against 62.61 inches in 2015.

Cost by repair type

Crack sealing is the smallest job. Fixr’s 2026 guide puts epoxy or polyurethane crack sealing at $200 to $1,000 per job, and This Old House prices structural injection of a leaking crack at $800 to $1,500 per crack. See foundation crack repair.

Slab repair with piers is the most common McKinney job. Fixr’s 2026 guide runs $1,000 to $10,000 for slab foundations and Modernize’s 2026 guide runs $3,000 to $7,500, because Fixr includes single-crack jobs at the bottom. See slab foundation repair and foundation piers.

House leveling is priced two ways. HomeAdvisor’s 2026 guide puts raising a foundation back to height at $3,000 to $9,500 and Modernize at $5,000 to $12,000, while This Old House and Fixr quote whole-house lifting at $20,000 to $30,000, a different scope. For McKinney slab and pier and beam homes the lower band applies. See house leveling.

Pier and beam work has its own line items. Modernize’s 2026 dedicated guide puts the typical range at $3,000 to $9,500. See pier and beam foundation repair cost.

Concrete leveling for driveways and patios costs less. Fixr’s 2025 guide puts the typical range at $500 to $1,700. See concrete leveling.

Drainage keeps the number from repeating. Modernize’s 2026 guide puts exterior drainage installation at $1,500 to $4,000. See foundation drainage.

Engineer, permit and plumbing line items in McKinney

These three items are easy to leave off an estimate and hard to avoid on a McKinney job. The engineer’s report is required by the city for pier work and runs $300 to $1,000 in This Old House’s 2026 guide, $340 to $780 in HomeAdvisor’s. If the engineer wants a soil report, This Old House prices that at $500 to $3,000. The city permit itself is $75 to $150 in Fixr’s guide. The plumbing test comes from the city’s requirement that the permit application say whether plumbing needs testing; a lift can stress drain lines under the slab, so many engineers require a test before and after. If that test finds a slab leak, the repair is plumbing work priced separately by a plumber, and should be fixed before the lift. This Old House also suggests a $1,000 to $2,500 contingency for unseen obstacles.

How to read an estimate

A written estimate you can compare against another should list each of these on its own line:

• Pier count, pier type and a diagram showing where each pier goes
• The per-pier price and the pier total, with interior piers marked separately from exterior ones
• Whether the hydraulic lift and re-leveling are included in the pier price
• The engineer’s report, and who is paying the engineer
• The city permit fee and who files it
• The plumbing test before and after the lift
• Concrete breakout and patching for any interior piers
• Landscape and hardscape restoration
• A contingency for unseen obstacles, stated as a number
• The warranty terms, attached, and the payment schedule

Compare estimates by pier count and pier type, not by the bottom line. Two contractors who agree on eight piers and disagree by thousands are disagreeing about pier type or about what they left off.

The foundation repair cost McKinney homeowners actually pay comes down to the pier count, the pier type, and whether the engineer, permit and plumbing test were on the estimate from the start.
