Foundation Repair vs Monitoring

Vertical hairline cracks (< 1/16") in interior drywall are almost always cosmetic — especially in corners or along taped seams. They happen from normal settling and temperature changes. What to do: Mark the end of the crack with a pencil and write the date. Check back in 6 months. If it hasn't grown, it's not structural.

If a door sticks in August but works fine in December — or vice versa — that's seasonal humidity, not foundation failure. DFW's expansive clay soil swells when wet (spring) and shrinks when dry (summer). What to do: Note the pattern. If the sticking is consistent year-round or getting progressively worse, that's a different conversation.

Tiny cracks in stucco or mortar joints (< 1/16") are often just thermal expansion. Brick and mortar expand and contract with temperature. What to do: Mark them, photograph them, and check back in 6–12 months. If they remain the same size and don't form a stair-step pattern, they're likely cosmetic.

If doors stick in multiple rooms and the problem is getting worse over time, the foundation is actively shifting. You don't need to fix it this week, but you should schedule an inspection and budget for repairs within the next year. Each year you wait adds roughly 5–10% to the repair scope.

A crack wider than 1/8" has already passed the cosmetic threshold. If it's stable (not growing over 6 months), it represents past settlement that may be done — or may reactivate in the next drought cycle. What to do: Get an inspection to determine if it's active. If stable, seal it and monitor. If active, plan repairs.

Standing water near the foundation isn't an immediate structural emergency, but it's a problem that compounds quickly. Each rain cycle saturates the soil, which expands and presses against your foundation. What to do: Address drainage within a year — French drains, grading, gutter extensions. This is often $2,000–$6,000 vs $10,000+ if you wait until foundation damage occurs.

This is the #1 red flag in DFW. A zigzag crack following mortar joints means the foundation has dropped enough to pull the brick veneer with it. This is never cosmetic. What to do: Schedule an inspection this week. The pier count and cost increase the longer it goes unaddressed.

When a door physically cannot close because the frame is so out of square, the foundation has shifted significantly. This level of movement puts stress on walls, windows, and plumbing. What to do: Schedule an inspection immediately. Repair costs increase roughly 15–20% per year at this stage.

If one side of a crack is visibly higher than the other — put a ruler across it; if there's a gap on one side — that's displacement. This means the foundation is actively settling unevenly. What to do: This is structural. Schedule an inspection this week. The differential will only increase.

Water intrusion through foundation cracks means the crack goes all the way through — it's not surface-level. This creates a structural problem AND a mold risk simultaneously. What to do: Address within days to weeks. Every rain event pushes more water through, expanding the crack and saturating interior materials.
