Foundation Repair Services in McKinney, TX

A foundation repair company McKinney homeowners can call for a straight answer should start with a measured inspection, not a sales pitch. Foundation repair means lifting a house that has settled, holding it on piers (a pier is a steel or concrete post driven under the slab or beam to carry the weight of the house down to stable soil), and correcting the drainage or plumbing problem that let the soil move in the first place. If your doors stick, your brick shows stair-step cracks, or one corner of the house feels lower than the rest, this page explains what the work involves, what the national cost guides say it costs, and what the City of McKinney requires before a crew breaks ground.

Every inspection is free and ends with a written estimate that lists the pier count, the pier locations and the warranty terms. Call (972) 555-0100 to book a same-week visit. Your request is routed to an insured local contractor who works in McKinney and across Collin County, and calls may be recorded for quality.

Signs you need foundation repair in McKinney

Movement rarely shows up as one dramatic crack. It shows up as a set of small annoyances that get worse after a dry summer or a wet spring. Look for these:

• Stair-step cracks in exterior brick, most often near corners and above windows. The cracks in brick page explains what separates a cosmetic crack from a structural one.
• Interior doors that stick in summer and swing freely in winter, or doors and windows sticking that no amount of planing fixes.
• A gap opening between the brick and a window frame, or between the garage door trim and the slab.
• Floors that slope toward one wall, or sagging floors in a pier and beam house.
• Cracks in the slab itself, in sheetrock above door frames, or where a wall meets the ceiling.
• The chimney pulling away from the house, or a fence line that no longer meets the wall where it used to.
• Plumbing that backs up, or a water bill that climbs with no visible leak, which can point to a slab leak under the house. A plumber tests for that, and the repair plan waits for the result.

One or two of these alone do not prove a foundation problem. Three or more on the same side of the house usually do. A foundation inspection in McKinney sorts the cosmetic from the structural with level readings taken across the floor at dozens of points.

What foundation repair involves in McKinney

The soil is the reason for almost all of it. The USDA NRCS Official Series Description for the Houston Black series, the Blackland Prairie clay under much of Collin County, puts its clay content at 40 to 60 percent and describes cracks 1/2 to 4 inches wide opening at 12 inches deep during dry periods. The NRCS fact sheet for the same soil notes that water enters it rapidly when it is dry and cracked and very slowly once it is wet, which is the wet-dry cycle that lifts one side of a slab and drops the other. The Texas Section of ASCE states that most foundations built in Texas are shallow, stiffened, reinforced slab-on-ground foundations, many placed on expansive clays like these.

The work follows a set order. It starts with the inspection: a crew lead walks the exterior, reads the brick and the doors, then takes elevation readings across the floor. Those readings show which corners have dropped and by how much. An engineer registered in Texas goes over the readings and writes the repair plan, including how many piers and where.

On day one of the repair itself, the crew marks pier locations along the perimeter, typically every 6 to 8 feet where the house has dropped, and digs a hole at each one down to the bottom of the footing (the thicker concrete edge the slab rests on). Three pier types are common in McKinney:

• Pressed concrete piers: precast concrete cylinders pressed into the ground one on top of the next, using the weight of the house as the press, until they refuse to go deeper.
• Steel push piers: steel pipe sections driven the same way, which reach deeper and are used where the clay is deep or the load is heavy.
• Helical piers: steel shafts with screw plates that are turned into the ground, used for lighter loads and additions.

Once every pier is set, the crew lifts the house with hydraulic jacks a fraction of an inch at a time, watching the readings, then locks each pier with steel shims and a concrete cap and backfills the holes. Interior piers on a slab house are reached by tunneling under the slab or by breaking through the floor, and the estimate says which.

Permits are not optional. The City of McKinney Building Inspections General Guidelines for Foundation Repair require a permit for any foundation leveling, pier or footing replacement, shimming or floor system replacement, on both slab-on-grade and pier and beam homes. The application must include an engineer’s letter and drawings that show the affected areas and whether the plumbing will need testing, and the city closes the permit only after the final engineer’s report is uploaded to its CSS portal. The contractor pulls the permit and schedules the plumbing test as part of the job.

What foundation repair costs in McKinney

The national guides agree closely. Fixr’s 2026 foundation repair guide puts the typical range at $2,200 to $8,200 with a national average of $5,200, and HomeAdvisor’s 2026 guide puts it at $2,225 to $8,133 with an average of $5,174. Both are national figures covering every repair type, so a single crack seal sits at the bottom and a full perimeter underpin sits at the top. The number that matters most for a McKinney slab is the per-pier price, which HomeAdvisor’s 2026 guide lists at $1,000 to $3,000 per pier.

Those are national ranges from named guides, not quotes, and the written estimate from your free inspection is the only number that applies to your house.

Choosing a foundation repair company McKinney homeowners can rely on

Texas does not license foundation repair contractors as a trade. The Texas Department of Licensing and Regulation lists no foundation repair or general contractor program among the industries it regulates, and a 2011 Senate bill that would have created one, SB 1399, said in its own analysis that no state regulation existed for the industry. That puts the checking on you. Five things to ask for before you sign:

1. A certificate of insurance, general liability and workers’ compensation both, with the contractor’s name on it. Crews are insured on every job routed through this site.
2. A written estimate that lists pier type, pier count, pier locations on a drawing, and what is and is not included (plumbing test, landscaping repair, interior access).
3. The engineer’s letter the city requires, from an engineer registered in Texas, and confirmation that the permit has been pulled.
4. A written warranty that states what is covered, how long it runs and whether it transfers to a buyer. Every job carries a written warranty.
5. An evaluation that follows the Texas Section of ASCE Guidelines for the Evaluation and Repair of Residential Foundations, now in Version 3 effective April 1, 2022.
