Warning Signs
Your house is trying to tell you something
San Antonio sits on clay soil that shrinks in the dry months and swells when it rains. That shrink-swell cycle moves foundations — and these are the signs it leaves behind.
01
Exterior brick cracks
Stair-step or widening cracks in brickwork can point to one part of the foundation moving differently from the rest.
02
Interior wall cracks
Cracks in drywall — especially diagonal cracks over doors and windows — often show up as the structure shifts.
03
Sticking doors & windows
When the foundation moves, frames move with it. Doors drag, windows bind, and gaps appear where they didn't before.
04
Cracking or buckling floors
Tile, wood, or slab floors that crack, lift, or buckle deserve a closer look underneath — not just a cosmetic fix on top.
05
Frieze board separation
When the trim where your wall meets the roofline starts pulling apart, the wall below it may be moving.
06
Not sure what you're seeing?
That's exactly what the free evaluation is for. Get it checked with ground-penetrating radar before you guess — or pay for a repair you may not need.
