Signs a House May Have Foundation Problems
A room-by-room read of the signs that are worth taking seriously, sorted by what they usually mean.
Working out what your foundation problem actually is
Nobody searches for the name of a repair method. They search for what the house is doing. These are the symptoms and decisions that come up most, what each one usually means, and what would tell the possibilities apart.

How to use these
Start from the symptom, not the service name. Each article opens with what you are actually seeing, works backward through what usually produces that exact sign, and says what would distinguish the possibilities from each other. There is a point in every one of them where the honest answer stops being something you can settle from an article. That point is named explicitly — a hairline crack in fresh drywall is worth a few weeks of watching before anyone else is involved; a foundation actively separating from a slab, or a retaining wall that has visibly moved recently, is not.
