Drywall Cracks vs. Foundation Cracks
Drywall cracks are common — and most are harmless. But some are the first indoor signal that your slab is moving. Here’s how to tell the difference before booking a free inspection.
Cosmetic patterns
Fine, straight cracks along tape seams or where the ceiling meets the wall are often from settling framing, humidity, or original construction — usually cosmetic.
Structural patterns
Cracks that radiate diagonally from the corners of doors and windows, reopen after patching, or pair with sticking doors point to foundation movement that may need steel-pier foundation repair.
The test
Patch it, then watch. If the crack returns within a season, the structure is still moving and a measured survey is worth it — especially in clay-heavy Pflugerville.
- Seam and ceiling-line cracks are usually cosmetic.
- Diagonal cracks from opening corners suggest movement.
- A crack that returns after patching is still active.
