Finding
Pebbledash delamination
What this usually means
Pebbledash is a render coat with embedded stones. When the bond between render and substrate fails, sections delaminate and fall. The hollow sound when tapped is the diagnostic.
Why it matters
Falling material is a public safety risk and indicates water ingress behind the coating.
Ask your surveyor
- Check:What proportion is delaminating?
- Check:Is there visible damp or decay behind?
Ask the seller
- Check:When was the pebbledash applied?
- Check:Has any work been done to address delamination?
Next steps
- •Get two written quotes from local trades before negotiating with the seller.
- •Speak to your mortgage broker before exchanging if the finding affects mortgageability.
