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

“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.”

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.
