Is My Foundation Failing? A Homeowner’s Guide

Spotting a crack or a sticking door can be alarming, but most homes aren’t “failing.” Here’s a calm, ordered way to tell real foundation movement from normal aging — before you call anyone.

Triage the signs

Walk the house and tally what you see. Isolated hairlines are usually cosmetic; clusters — brick cracks plus sticking doors plus sloping floors — point to movement worth a free inspection.

Stair-step cracks in brick
Doors that won’t latch
Floors that slope underfoot
Gaps at trim or ceilings
Cracks reopening after patching
A visibly low corner

Rate the severity

Width, growth, and clustering matter more than any single crack. Multiple correlated, growing signs move you toward the “act” end of the scale and steel-pier stabilization.

Confirm with measurement

The only definitive answer is a ±1/8-inch elevation survey. Many homes simply need monitoring — common findings across San Antonio and Austin.

Key takeaways
