Best Foundation Repair Companies in Plano, TX (2026)

Plano’s expansive clay soils — the same black and gray Blackland Prairie clay that runs through neighborhoods like Legacy, Willow Bend, and older subdivisions near downtown — shrink and swell with every wet and dry cycle, making foundation movement one of the most common and costly home repairs in Collin County.

This guide compares six verified foundation repair companies serving Plano as of mid-2026, so you can make a decision based on facts rather than a rushed sales call.

Best for a Long Track Record: Dalrock Foundation Repair

Why Plano homeowners consider them

Dalrock has been operating in the Dallas and North Texas market for more than 40 years, covering residential and commercial properties across Plano, Frisco, McKinney, Allen, and surrounding cities. They handle foundation repair, drainage repair, and concrete pier work, and they back completed jobs with a lifetime transferable warranty — a meaningful feature if you plan to sell your home, since the warranty passes to the next owner. For homeowners in older Plano subdivisions where foundations have seen multiple drought cycles, a company with that kind of institutional knowledge of local soil behavior is worth a call.

Best for Independent Engineering Oversight: Pinnacle Foundation Repair

Why Plano homeowners consider them

Pinnacle is headquartered right here in Plano at 2121 W Spring Creek Pkwy, Ste 236, which matters when you need someone familiar with local permitting requirements at the City of Plano’s Development Services department. The company was founded by a third-generation foundation repair specialist with more than 20 years of hands-on experience, and it holds a BBB A+ rating with accreditation since December 2019. What sets Pinnacle apart is their practice of having an independent, nonaffiliated structural engineer review and sign off on every foundation plan before work begins. That layer of third-party accountability is unusual in this industry and gives homeowners a degree of confidence that the recommended scope of work is not inflated. They offer a lifetime warranty on steel and steel transition systems.

Best for Nationally Backed Warranty with Local Crews: Groundworks

Why Plano homeowners consider them

Groundworks operates with in-house certified crews local to the North Texas area, which means you are not dealing with rotating subcontractors. Their approach leans on helical piers and push piers — methods well-suited to the deep clay profiles common under Plano slabs — to stabilize foundations against ongoing soil movement. They offer free inspections, carry a BBB A+ rating, and their lifetime warranty is backed at the national company level, which can be reassuring for homeowners who worry about a smaller local shop closing before a warranty issue arises. The trade-off with larger companies is sometimes less flexibility on scheduling or price negotiation, so get a written quote and compare it against local competitors.

Best for Drainage Solutions and Pier-and-Beam Work: Cornerstone Foundation Repair

Why Plano homeowners consider them

Founded in 1995 and serving North Texas for more than 30 years, Cornerstone brings a depth of experience with the specific failure modes common in this region. They specialize in slab foundation repairs, pier and beam repairs, drainage solutions, and engineering-backed remediation plans. Their BBB A+ rating has been maintained across more than two decades in business. Drainage is often an overlooked piece of the foundation puzzle in Plano — poor grading or clogged gutters can direct water toward a foundation and accelerate clay expansion. Cornerstone’s focus on drainage as part of the overall repair picture makes them a practical choice for homeowners dealing with both structural movement and water management issues on the same property.

Best for an Honest Assessment Before You Commit: Granite Foundation Repair

Why Plano homeowners consider them

Granite Foundation Repair serves Plano and broader Collin County and handles concrete slab, pier and beam, and other foundation types. What stands out in their public-facing approach is a noted commitment to straightforward evaluations: the company acknowledges that nearly 30 percent of the homes they assess do not need extensive foundation repairs. That statistic is worth noting in an industry where over-diagnosis can be a real problem. If you have cracks that look alarming but may be cosmetic, or if you want a second opinion after another company quoted a large repair project, Granite is worth including in your comparison process.

Also Worth a Call: MetroTex Foundation

Why Plano homeowners consider them

MetroTex Foundation appeared in Yelp’s updated rankings for top Plano foundation repair providers as of May 2026. Reviewers specifically describe the owner’s approach as “refreshingly honest and practical” and note that the advice they received “may save you a ton of money” — language that suggests the company is willing to tell you when a repair is not necessary or can wait. Because an official website URL could not be independently confirmed at the time of this writing, locate MetroTex through Yelp or the BBB directly before reaching out, and verify current licensing and insurance as you would with any contractor.

Frequently Asked Questions

How much does foundation repair cost in Plano, TX?

Costs vary widely depending on the extent of movement, the number of piers needed, and whether drainage work is required. Minor repairs may run a few thousand dollars, while significant slab stabilization projects can reach $15,000 or more. Getting at least three written quotes from companies on this list is the most reliable way to understand what your specific situation should cost.

Do foundation repair companies in Plano pull permits?

The City of Plano requires permits for structural repairs in most cases. Before signing any contract, ask the company whether they will pull the necessary permits through Plano’s Development Services department and whether an engineer-stamped plan is included. Companies like Pinnacle that involve independent structural engineers are already structured to meet this requirement.

What causes foundation problems in Plano specifically?

Plano sits on expansive Blackland Prairie clay that absorbs moisture and swells during wet seasons, then contracts sharply during droughts — the kind of soil cycle that stresses concrete slabs repeatedly over time. Tree roots near the foundation and inadequate drainage can accelerate the process. These are not generic Texas problems; they are specific to the clay composition in this part of Collin County.

What should I look for in a foundation repair warranty?

Look for a lifetime transferable warranty in writing, and confirm whether it covers both labor and materials. Ask what voids the warranty — some companies exclude future movement caused by drainage problems the homeowner did not address. A warranty that transfers to the next owner adds real value at resale.

Should I get more than one estimate?

Yes. Foundation repair recommendations can vary significantly between companies, both in scope and price. Getting two or three written estimates lets you identify outliers on either end and ask informed questions about why the recommendations differ. No single quote from a company with a financial interest in the job should be your only data point.
