Finding
Render cracking
What this usually means
Render cracking can be cosmetic (hairline shrinkage) or symptomatic (pattern matches movement of underlying structure). Surveyors look at the pattern, location, and any associated internal damp.
Why it matters
Failed render lets water in behind, causing damp, mortar erosion, and timber decay.
Ask your surveyor
- Check:Is the cracking cosmetic or symptomatic of movement?
- Check:Is there evidence of water ingress behind?
Ask the seller
- Check:When was the render last applied?
- Check:Has any work been done to address the cracking?
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.

How MyPropertyScan produces this guide, and what it is not
Published by MyPropertyScan and written by Ziad Nasr, who is accountable for its accuracy. No page here is written or reviewed by a chartered surveyor, conveyancer or regulated adviser, and we do not claim otherwise.
This page is not:
- Chartered surveying: we do not inspect properties or produce RICS Home Survey reports
- Legal advice: we do not act as conveyancers or advise on title, tenure or contracts
- Mortgage or insurance advice: we are not regulated by the FCA and give no recommendations
Figures and process steps come from the published UK datasets and standards listed on this page, not from professional practice. Pages are updated when source coverage, survey cost assumptions, or lender and legal requirements materially change. Dataset limitations are set out on the methodology page.

Sources used
We use UK public and specialist sources where they are available. Public datasets can be incomplete, delayed, or missing for some addresses. Treat them as a starting point, not as a replacement for professional advice.
Source standard: preference goes to official government datasets, statutory bodies, professional standards, and primary dataset publishers. We cite the source family on the page and explain coverage limits rather than filling gaps with unsupported estimates.
