Survey finding
Spalling brickwork: what it means and what to do
Spalling brickwork is one of the most common pre-war and inter-war wall findings on UK surveys. This page covers cause, cost, and how lender and insurer markets treat it.

Finding
Spalling brickwork
What this usually means
Spalling brickwork is the breakdown of the outer face of a brick, the face flakes, splits, or comes away. Most often caused by frost: water enters porous brick, freezes, expands, and pops the face off. Other causes include sulphate attack on brick or mortar, salt crystallisation, or mechanical damage. Spalling is cosmetic at first; left unaddressed, structural integrity of the wall reduces.
Why it matters
Localised spalling on a few bricks is a maintenance item. Widespread spalling on a whole elevation, particularly weather-facing, indicates failed pointing, defective DPC, or exposure that needs addressing before further damage. Lenders rarely refuse on spalling but may impose retention if structural integrity is in question.
Ask your surveyor
- Check:Is the spalling localised to a few bricks or affecting whole elevations?
- Check:Is the cause frost, sulphate attack, salt, or mechanical?
Ask the seller
- Check:When was the property last repointed, and on which elevations?
- Check:Have any brick replacements been carried out, and by whom?
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.

What you need to know
Severity
Maintenance item. Worth quoting and including in negotiation.
Typical cost to fix
Localised brick replacement (pop and replace 5–10 bricks): £400–£900. Repointing a single elevation: £1,200–£3,500. Full elevation re-build with replacement bricks: £4,000–£10,000+. Specialist matching of bricks for older properties adds 20–40%.
Mortgage impact
Standard for most lenders. Significant elevation-wide spalling on a non-standard construction property may trigger a retention until repair is documented.
Insurance impact
Spalling from a documented insured event (storm, impact) can be claimable. Wear-and-tear spalling is the buyer's responsibility.
When to pull out
Pull out only if multiple elevations are affected, structural integrity is compromised. The seller refuses to engage, and remediation cost approaches 5%+ of price.
When to renegotiate, and by how much
Get a quote for repointing and brick replacement. Negotiate on quote plus 15%. For a single elevation, deduction is typically £1,500–£3,500.
