Foundation Warning Signs in Garland, TX
Texas clay soil gives plenty of warning before foundation damage gets serious. Here's what to look for — and what each sign means.
Why Texas Clay Moves Your Foundation
Garland sits on expansive clay soil. When it rains, the clay absorbs water and swells; in drought, it dries and shrinks — sometimes by several inches. North Texas weather swings between soaking storms and dry spells constantly, so the ground under your home is always moving. When one section of soil swells or shrinks more than another, your foundation moves unevenly. That's called differential settlement, and it's behind nearly every foundation problem in DFW.
Three things make it worse: poor drainage (water pooling at the slab), large trees (roots pull moisture from the soil, shrinking it on one side of the house), and plumbing leaks under the slab (a constant, hidden water source).
The Warning Signs, Explained
- Stair-step cracks in brick veneer
Cracks that zigzag through mortar joints in a staircase pattern. This is the textbook sign of differential settlement — one part of the foundation dropping relative to another.
- Diagonal drywall cracks above doors and windows
Openings are the weak points in a wall. When the foundation shifts, stress concentrates there first, cracking the drywall at 45-degree angles.
- Doors and windows that stick or won't latch
Frames twist as the foundation moves. A door that used to close fine and now jams is telling you something changed underneath.
- Sloping, uneven, or bouncy floors
Set a marble down and watch it roll, or feel the slope underfoot. On pier & beam homes, bouncy floors often mean failed shims or rotted wood below.
- Gaps between walls and ceiling or floor
Separation at the trim line — crown molding pulling away, baseboards gapping — means the wall and the structure around it are moving at different rates.
- Chimney pulling away from the house
Chimneys often sit on their own footing. When the main foundation settles and the chimney doesn't (or vice versa), a visible gap opens up.
- Cracks in the slab or garage floor
Hairline shrinkage cracks are normal in concrete. Wide, offset, or growing cracks — especially ones you can fit a coin into — deserve an evaluation.
- Water pooling near the foundation
Not a foundation symptom, but a cause. Standing water after rain means drainage is feeding the clay cycle that moves foundations.
When to Call for an Evaluation
One small hairline crack? Monitor it — mark the ends with a pencil and check monthly. But call for a professional evaluation when you see multiple signs at once, cracks that are growing, doors that recently started sticking, or any sudden change after heavy rain or drought. Foundation problems don't fix themselves, and in expansive clay they rarely stay the same size — early repairs are smaller repairs.
