Bowing, leaning or bulging walls

What a bowing wall looks like

• A wall that curves inward or outward when you sight along it
• Gaps opening where the wall meets the ceiling or floor
• Brick veneer pulling away from the house or from window frames
• Horizontal cracks along the wall
• Retaining walls or garage walls that lean

Why walls bow

Most homes along I-35 sit on slabs or pier and beam foundations rather than basements, so classic basement wall bowing is less common here. Walls can still bow or lean when the foundation under them moves, when clay soil pushes against a below-grade or retaining wall, when water collects against the house, or when framing has been damaged by moisture. Drainage is often part of the picture, see foundation drainage.

Why it should be looked at soon

A bowing wall can be a structural concern, and the cause is not something you can confirm from the outside. Do not try to brace or pull a wall back yourself. Have a qualified pro inspect it, and if they recommend it, a structural engineer.

Track what you can

Hold a long level or string line against the wall and photograph the gap, with the date. Note any new wall cracks, sticking doors or floor slope nearby.

None of these signs proves a foundation problem on its own, and a guide cannot tell you what is happening under your house. Have a qualified pro inspect it before you decide on any repair.

For typical national price ranges, including crack sealing and piering, see the foundation repair cost guide. Those are national figures, not quotes.
