Not sure when to replaster walls in your home? Over time, even the best plaster can crack, sag, or bubble—often hiding deeper issues like damp or poor adhesion. In this guide, we explain the 7 key signs that it’s time to consider replastering, and how expert help can restore your walls to a flawless finish.
1. Cracks in the Plaster
Hairline cracks might seem harmless, but they can indicate movement in your property or poor adhesion. Larger cracks, especially near ceilings or corners, are a clear sign that replastering may be needed to restore a smooth and safe finish.
2. Bubbling or Flaking Paint
When paint starts bubbling or flaking, it’s often due to moisture behind the plaster. This could mean the plaster has lost its bond or there’s an issue with damp. Replastering and treating the cause early can save you bigger headaches down the line.
3. Damp or Mould Patches
Persistent damp patches or mould growth on your internal walls are more than just cosmetic problems. They’re usually signs of water ingress or poor ventilation—and damaged plaster is often the result. Replastering may be required after damp proofing treatment.
4. Hollow Sounds When Tapped
If your walls sound hollow when lightly tapped, it means the plaster has come away from the substrate. This delamination reduces the wall’s strength and is a common reason for professional replastering.
5. Sagging or Bulging Plaster
Loose or sagging plaster—especially on ceilings—is a serious safety risk. It can collapse without warning. If you spot uneven surfaces or feel the plaster shift under pressure, it’s time to call in an expert.
6. Uneven Surfaces After Decorating
If your paint or wallpaper highlights lumps, dips, or rough patches, it’s a strong sign your walls need attention. A fresh skim coat of plaster can give you a level, modern finish ready for decorating.
7. Water Damage After Leaks
After a roof, pipe, or radiator leak, plaster can become soft, crumbly, or stained. Even if dried out, it may have lost structural integrity. Replastering is often necessary to fully restore the affected area.
Why Timely Replastering Matters
Ignoring plaster issues can lead to deeper structural problems, from trapped moisture to electrical hazards. Early intervention protects your property and improves your home’s appearance and value.
