“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.”

Curb view: tap a marker to explore common symptoms
Gaps Around Windows
Visible gaps between window frames and walls, or windows that are hard to open, can result from wall movement tied to foundation shift.
Brick Cracks
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.
Sticking Doors
Doors that stick, drag, or no longer latch properly may mean the frame has shifted because the foundation is no longer level.
Uneven Floors
Floors that slope, dip, or feel uneven underfoot can indicate settlement of piers, beams, or the slab itself.

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

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

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

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.
