Cracks in walls can result from finish movement, moisture, or changes in structural support. Pattern, location, growth, and other symptoms are more useful than any one crack-width rule.

Uneven foundations develop when support changes differently across a structure. Soil, drainage, leaks, fill, and deteriorated supports can all play a role, often together.

Root barriers can redirect root growth away from selected areas. Their usefulness depends on tree condition, soil, drainage, and careful placement; they are not a universal cure for settlement.

Pier and beam foundations provide access beneath raised homes, but their piers and beams still need reliable support and moisture control. Elevation alone does not prevent settlement or flood damage.

Foundation repair can reduce uncertainty when selling a home. Clear documentation helps buyers understand completed work, remaining issues, and written warranty terms, without guaranteeing a higher sale price.

Signs foundation repair is needed can include changing cracks, uneven floors, or gaps around openings. These observations call for an evaluation; they do not prove that every symptom requires structural repair.

Foundation issues in older homes can reflect years of moisture exposure, repairs, additions, or changing support. Age alone does not make a home unsafe, and older construction should be evaluated on its condition.
