Questions about Foundation Cracks Guide

Clear answers first. If one question changes the deal, bring it into the review before you move money.

Q1How do I read a foundation crack?+

By direction and width. Vertical hairlines are usually shrinkage; diagonal cracks suggest settlement (watch them); horizontal cracks are often the most serious. Measure the width and note whether it's growing.

Q2What does efflorescence or seepage on the crack mean?+

Water is moving through it. On wet slopes, that white mineral residue or active seepage signals a moisture path, which turns a cosmetic-looking crack into a drainage-and-structure question worth pricing.

Q3Cosmetic, watch, or specialist — how do I decide?+

Isolated hairline: monitor. Diagonal but stable: watch and measure. Horizontal, displaced, actively wet, or a repeating pattern: engineer, before it becomes a price conversation the wrong way.

Q4Does one crack matter, or is it the pattern?+

The pattern. An isolated hairline is common in concrete; the same crack type repeating around the foundation, or matching cracks inside and out, is what points to movement rather than curing.

Q5Should the seller fix it or give a credit?+

Depends on the diagnosis. A monitored hairline needs neither; a confirmed structural or drainage issue is a repair, a credit, or a walk. Get the estimate first — you can't negotiate a number you don't have.

Q6I have photos and an inspection note — what now?+

Have them read by the right specialist before the contingency ends. Lining up that read and turning it into an ask is part of a Real Estate Review.
