Quick, low-risk steps

  1. Record changes by date instead of deciding from one crack.
  2. Photograph from the same safe position with a reference scale.
  3. Note sticking doors, uneven floors, leaks, and recent weather.
  4. Separate an independent engineering opinion from a repair bid.
  5. Compare quantities, engineering, restoration, and warranty terms.

Start with an Independent Engineering Evaluation

A slab foundation repair should begin with a report from a Texas-licensed structural engineer who has no financial interest in the repair company. This report identifies the cause and extent of movement, recommends a repair method, and specifies quantities such as pier locations and depths. Without it, a contractor’s proposal may be based on sales targets rather than structural need.

The engineer’s report should include elevation measurements, a plumbing leak test recommendation, and a repair plan that meets local building codes. Ask for a sealed report that you can use to obtain comparable bids. This step protects you from unnecessary or incomplete work.

  • Hire a Texas-licensed structural engineer, not a foundation repair salesperson.
  • Request a sealed report with repair method, pier locations, and depths.
  • Ensure the report includes elevation data and a plumbing test recommendation.
  • Use the report to get multiple bids on the same defined scope.

Understand Soil and Water in the Dallas–Fort Worth Area

The expansive clay soils common in Dallas–Fort Worth shrink and swell with moisture changes, which can stress slab foundations. The USDA Natural Resources Conservation Service explains that soil risk varies by location and requires site-specific evaluation. The USDA Web Soil Survey can provide general soil map information, but it is not a substitute for a geotechnical investigation.

Before repair, address drainage and plumbing leaks that may be causing soil movement. A plumbing static test can identify under-slab leaks. Proper grading, gutters, and downspout extensions help keep water away from the foundation. An engineer can advise on necessary drainage corrections.

  • Check USDA Web Soil Survey for general soil types in your area.
  • Have a licensed plumber perform a static test for under-slab leaks.
  • Ensure gutters, downspouts, and grading direct water away from the slab.
  • Ask the engineer if soil moisture stabilization is needed before or after repair.

Compare Repair Proposals on the Same Scope

Once you have an engineering report, request bids from at least three reputable foundation repair contractors. Each bid should follow the engineer’s specified method, quantities, and depth requirements. Be wary of bids that deviate significantly from the report or that use vague language like “as needed.”

A detailed proposal includes the number and type of piers, installation depth or refusal criteria, bracket specifications, concrete pressure and mix design, and a clear plan for interior and exterior restoration. It should also state who handles permits and inspections, and what triggers a change order.

  • Get at least three bids based on the same engineering report.
  • Compare pier type, quantity, depth, and bracket specifications.
  • Look for a clear restoration plan: concrete replacement, drywall, paint, landscaping.
  • Confirm permit responsibility and inspection schedule in writing.

Secure a Transferable Warranty and Final Documentation

A meaningful warranty covers the repair system, not just the materials, and is transferable to a new owner. It should specify what is covered, for how long, and what would void it. Ask for a sample warranty document before signing a contract.

After work is complete, you should receive a final engineer’s letter or inspection report confirming the repair was installed per the plan, along with elevation readings, pier installation logs, and permit close-out documents. Keep these for future reference or resale.

  • Request a sample warranty and review transferability and exclusions.
  • Ensure the warranty covers the repair system, not just materials.
  • Obtain a final engineer’s inspection report and elevation data.
  • Keep all permits, inspection records, and installation logs.

Common questions

What homeowners ask next

Do I need an engineer before getting foundation repair bids?

Yes. An independent Texas-licensed structural engineer provides an unbiased repair scope. This allows you to compare bids on the same defined work and avoid unnecessary or insufficient repairs.

How do I know if my slab foundation problem is caused by soil or a plumbing leak?

A plumbing static test can identify under-slab leaks. An engineer can also evaluate soil conditions and drainage. Both factors often contribute to foundation movement in the expansive clay soils of Dallas–Fort Worth.

What should a foundation repair warranty include?

A good warranty covers the repair system, is transferable, and clearly states coverage duration, exclusions, and what would void it. Ask for a sample document before signing a contract.
