Foundation Diagnostic

What Are You Seeing Around Your Home?

Select a symptom to learn what it may indicate, why it happens in Houston, and what Allied checks during your free evaluation.

Brick Cracks

What it may indicate

Stair-step or horizontal cracks in brick or mortar can signal foundation movement. The wall may be shifting as soil beneath the home expands or contracts.

Why it happens in Houston

Houston's expansive clay soil swells when wet and shrinks during dry spells. That cycle puts uneven pressure on exterior walls and can open cracks in brick veneer.

What Allied checks during inspection

  • Crack pattern, width, and direction on exterior walls
  • Separation between brick and window or door frames
  • Soil moisture and drainage around the affected area
  • Interior signs that confirm exterior movement

We recently had warranty work completed on our foundation repair, and while Allied Foundation stood behind their warranty and completed the work, Pete is the person who truly made the experience exceptional.Pete was actually the original representative who sold us our foundation repair, and years later, when warranty work was needed, he stepped in once again and reminded us why we trusted him in the first place. At the beginning of the process, we often felt like our concerns weren't being fully understood and the experience was becoming increasingly stressful. The moment Pete got involved, everything changed.Pete didn't treat us like just another customer or warranty claim. He took personal ownership of the situation and made sure we felt heard, respected, and supported from start to finish. He consistently followed up, answered every question, addressed every concern, and gave us confidence that things were being handled the right way. When anxiety and uncertainty started to creep in, Pete was the person who brought reassurance and peace of mind.What impressed us most was that he didn't just talk about customer service—he demonstrated it. He was there during the work, remained actively involved throughout the process, and even stayed after hours when the job ran long to make sure everything was completed properly and that we were comfortable with the outcome. It's rare to find someone who is so invested in taking care of their customers long after the original sale, but Pete never stopped looking out for us.I also want to recognize the foreman, David. He was a charming, kind professional who immediately helped put us at ease. He understood that the situation inside our home felt abnormal and unsettling to us, even though it was something his team deals with regularly. He calmly explained the process, reassured us that everything could be fixed, and brought a level of confidence and compassion that made a stressful day much easier to get through.Foundation work is stressful no matter who you are, but Pete's dedication, professionalism, integrity, and genuine care turned what could have been an overwhelming experience into one where we felt supported every step of the way. Allied Foundation is incredibly fortunate to have someone like Pete representing their company. Quite simply, he is the kind of employee every company wishes they had and every customer hopes they get to work with.

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.

We had Allied Foundation replace our main sewer line, and the whole experience was great. They replaced everything from the slab all the way out to the city tap, around 100 feet, and tied in the laundry line from our garage while they were at it. Part of the run had some tough access under our deck, and they worked through it without issue. Everything was permitted and passed city inspection the very next day.The crew cleaned up well and backfilled the trench, and they're coming back to make sure it all settles level and to tidy up the new cleanouts that were added. Luis was responsive the whole time and easy to reach with any questions. Their pricing was very competitive, and out of the several bids we got, they offered the best scope for the price, with a 3-year warranty on top. Would absolutely recommend them and use them again in the future! Thank you!

Houston Soil Science

Why Houston Clay Soil Affects Your Foundation

Understanding local soil behavior helps explain the cracks, sticking doors, and uneven floors you may be seeing.

Wet season

Cross-section of a slab foundation with clay soil expanding upward against the slab
Expansive heave

Moisture active zone

Heavy rains saturate Houston clay. The soil expands and pushes upward against the foundation slab, stressing walls, doors, and windows.

Dry season

Cross-section of a slab foundation with clay soil shrinking away and leaving a void under the edge
Shrinkage settlement

Moisture active zone

Void / loss of support

During dry periods, clay contracts and can pull away from the slab edge. Support becomes uneven. Cracks and sticking doors often follow.

Up to 0 ft

Moisture Active Zone

Houston's expansive clay is most active in the upper soil layer, the zone where seasonal moisture changes cause the most movement beneath your slab.

Seasonal

Wet / Dry Cycle

Clay swells when saturated after heavy Gulf Coast rains, then shrinks during dry spells. That repeated push-and-pull stresses foundations over time.

Contributors

Roots & Drainage

Large trees draw moisture from soil near the slab, and poor drainage oversaturates clay. Both can worsen uneven support. Root barriers and drainage help.
