Trained Crews. On-Time Results. Grade A Cleanup.

We tailor the size of our trained crews and experienced supervisors to fit the size of the project. Most homes can be completed in a single day with the manpower we have at our disposal. Extensive foundation repair work, on the other hand, can take 2 to 3 days.

Forty-four years of efficiency and time management simplifies the process and achieves the best on-time results. Our company will bring your home back to its original state with attention to great detail. This process helps to alleviate the stress and anxiety our customers may feel during the repair process.

About This Service

Houston foundation repair is often driven by expansive clay soil and extreme wet-dry cycles. Seasonal drying can shrink the soil around your home; heavy rain makes it swell. That movement stresses slab and pier foundations and can lead to cracks, sticking doors, and uneven floors.

Allied Foundation Repair is a family-owned Houston team that has repaired more than 75,000 homes since 1982. We start with a free foundation evaluation with clear answers about what you are seeing, whether movement is active, and which repair approach fits your home, without pressure.

Whether you need slab foundation repair, pier-and-beam support, or a plan that also addresses drainage and plumbing under the slab, our crews focus on quality work at a reasonable price and leave your property as clean as we found it.

Why Houston Homes Need Foundation Repair

Greater Houston’s gumbo clay expands when wet and contracts during drought. Poor drainage, plumbing leaks under the slab, and large trees near the perimeter can make that movement worse. Over time, the foundation can settle unevenly, especially on older slabs and homes that have already seen flood or drought stress.

Catching foundation cracks and related warning signs early helps you avoid more extensive structural damage. A professional evaluation separates cosmetic issues from active settlement so you know what actually needs repair.

How Allied Approaches Houston Foundation Repair

Your free evaluation includes a step-by-step look at interior and exterior conditions. We explain what we find in plain language and recommend a repair plan suited to your foundation type and soil, not a one-size-fits-all pitch.

For many Houston homes, stabilization uses driven concrete piers or pile-guard pier systems designed to track straight and protect the pier’s full compression strength. Steel and Integrated options are available when conditions call for them. Most homes can be completed in a single day; more extensive work may take two to three days, depending on scope and weather.

  • Free foundation evaluation with clear, pressure-free recommendations
  • Solutions for slab-on-grade and pier-and-beam conditions
  • Lifetime limited transferable warranty on qualifying foundation repair
  • 100% financing available through our lender partners for qualified projects

How the Process Works

  1. Step 1

    Free evaluation

    We inspect what you are seeing inside and outside the home and determine whether foundation movement is the cause.

  2. Step 2

    Clear repair plan

    You receive a written recommendation covering method, scope, timeline expectations, and warranty coverage for qualifying work.

  3. Step 3

    Stabilization and leveling

    Experienced crews install the approved pier system and restore support under the foundation with skilled supervision on site.

  4. Step 4

    Cleanup and walkthrough

    We complete the job with careful cleanup so your home looks as good as it did before we arrived, and review what was done.

Repair Options

Foundation Pier Systems We Offer

Although we use the Pile Guard Pier extensively, we offer a variety of foundation repair piers with variable price points for your consideration.

Pile Guard Pier

Hardened mold-formed polymer joint guards connect concrete piers driven to a point of refusal, assuring positive alignment and interlock.

  • Solid pressure-tested concrete cylinders aligned and connected with hardened polymer couplings to support the foundation
  • No holes through the middle of the concrete cylinders, preserving strength and stability
  • Coupled segments track straight down instead of drifting in an uncontrolled direction

  • Solid concrete cylinders driven to a point of refusal
  • 20-ton hydraulic jacks raise and level the foundation
  • The lift is secured with solid concrete blocks and steel shims

Integrated Power Plus

Combines the tensile strength of steel with the compression strength of concrete.

  • Steel segments are driven into the soil first, allowing solid concrete cylinders to penetrate the expansive clay
  • A portable manifold lifting system raises the structure evenly
  • A centrally located pier lock bracket secures the lift

Tips to Protect Your Home

  • Keep soil moisture more consistent around the foundation during dry spells (soaker hoses can help when used carefully).
  • Direct gutter and downspout water away from the slab so clay soil does not stay oversaturated.
  • Fix under-slab plumbing leaks promptly. Moisture under the center of a slab is a common Houston problem.
  • Watch for new cracks, sticking doors, or sloping floors after drought or heavy rain cycles.

Allied installed 9 piers on my home to repair the foundation. They were prompt, efficient and left the work cleaned up. Excellent experience.

We had 16 piers installed. It was our second estimate. The first company was going to install 8 piers for more money and they didn't even notice the garage needed piers too. Also, we recently sold the house and there was no fee or warranty to transfer, it stays with the house. The other company charges 250 and the new buyer has 90 days to transfer the warranty or they lose it. We definitely recommend Allied, they're an honest company and did a great job.
