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.

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

“It was an overall good experience. They did a great job of doing the drilling thru the patching up the shoes that they dug . I appreciate the job that they did.”

“Frank’s crew was top notch. They met with us before they began the work and made sure they knew what landscaping we wanted to save. They put plywood down to protect the mulch and flowers in the area. When they were finished, the sidewalk they hammered out was better than before, the house was fantastic. The next day, they came back to check the water lines to make sure there were no issues. Strongly recommend Allied to all my friends and clients.”
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.

Built Different
The Pile Guard Pier Difference
No holes drilled through the concrete. No rods or cables running through the pier. Just full-strength concrete, coupled straight down.
What some companies don't tell you
Some foundation companies push standard cylinders straight into the ground with no way to control direction. They can drift east, west, or even toward a neighbor's yard, and there's no way to verify where they end up.
The Pile Guard Pier way
- No holes drilled through the concrete cylinder, since drilling removes material and weakens the pier
- No steel rods or cables run through the pier, since running hardware through the cylinder sacrifices the concrete's full compression strength
- Segments join with hard polymer couplings, keeping the full compression strength of the concrete intact
- Coupled sections track straight down, rather than drifting in an uncontrolled direction
Also available: Steel piers available · Hybrid steel-and-concrete piers available
