5 Signs Your Ceiling Needs Repair

Published 15 September 2026 · Guides

Not every ceiling crack is serious, but some are warnings.

1. Sagging or bulging

A bulge suggests plaster is losing its grip. Keep the area clear.

2. Wide or growing cracks

Hairline cracks are common; cracks that widen need checking.

3. Stains

Stains often mean a leak. Fix the source first.

4. Flaking or crumbling

Plaster that crumbles may be damp-damaged.

5. Visible lath

Exposed lath means plaster has failed.
