What is brick spalling, and who should look at it?

Brick spalling is the name people use when the outer face of a brick flakes or crumbles away. In a Cheshire wall that is a reason to ask a builder what the damage means, not a reason to cut the face off yourself.

What are you actually looking at?

Spalling is the word used when the outer skin of a brick breaks away, in flakes or in a soft crumble, so the face is no longer the flat surface it was laid as. You might see it on a few bricks at the base of a wall, or in a band under a window, or scattered up a gable. The pattern matters more than the name. A photo of the whole wall, and a closer photo of one brick, tells a builder more than the word alone.

This page does not give a cause. Frost, salts and old coatings are all things people guess. None of those guesses is printed here as a fact. What the Planning Portal does say is what a wall is supposed to do: resist moisture from the ground, which normally means damp-proof courses, and resist the weather getting from the outside to the inside [S1]. It also says brickwork generally gives good weather resistance on its own, while blockwork will normally require rendering [S1]. If the face is breaking up, ask whether that resistance is still there.

What permissions sit around a repair?

The Planning Portal says you do not need to apply for planning permission for repairs, maintenance or minor improvements, such as painting your house [S2]. If you live in a listed building, you will need listed building consent for any significant works, whether internal or external [S2]. GOV.UK says works that alter a listed building in a way that affects its character as a building of special architectural or historic interest require listed building consent, and that doing those works without consent is a criminal offence [S3]. Replacing a scatter of bricks on a listed house is a question for the local planning authority before anyone starts.

Cladding is a different operation from piecing-in bricks. In a conservation area, a national park, an area of outstanding natural beauty or the Broads, the Planning Portal says you need planning permission before cladding the outside with stone, artificial stone, pebble dash, render, timber, plastic or tiles [S2]. Outside those areas, cladding may be carried out without an application if the materials are of a similar appearance to those used in the construction of the house [S2].

GOV.UK: find your local council for building control. QuoteZila is not affiliated with this organisation.

Does building regulations approval come into a flaking wall?

Re-decorating the surface of an existing wall would not normally require approval [S4]. External walls are thermal elements, and a renovation of a thermal element can trigger a requirement to upgrade the insulation at the same time [S4]. A coat of masonry paint is not the same sentence as rebuilding the outer leaf. Ask the builder which description fits, and ask building control if the two of you disagree.

GOV.UK says building regulations approval is different from planning permission, and you might need both [S5]. You do not arrange the approval yourself where a competent person scheme member does the work [S5]. Brick repairs are not automatically that route. Say what is being replaced.

What should you not do while you wait?

Do not knock the loose face off with a hammer to "tidy it". Do not rake the joints out above your head. Do not coat the wall in a sealer because a tin suggested it. The Planning Portal's weather page is about the wall resisting moisture, not about a household coating [S1]. If the damage is at height, it is the same reason you would not walk a roof: leave it to someone set up to work there.

Citizens Advice says some traders charge for quotes, so ask first, and to get written quotes from at least 3 traders [S6]. A quote is a fixed price and an estimate is a rough guess [S6]. Ask the builder to write whether they will piece-in new bricks, repoint only, or recommend a wider repair, and what happens if the brick behind the flake is soft. A business registers for VAT when taxable turnover for the last 12 months goes over £90,000, or is expected to in the next 30 days [S7]. Ask if the total includes it.

Jobs you might post

These are examples, not taken from real job posts.

  • A band of flaking bricks along the bottom of a front wall, photos from the pavement. Ask whether a damp-proof course is part of the look, or a separate trade.
  • Scattered flakes on a gable, all above the first-floor windows. Say nobody should work off a ladder you own. Ask for access in the quote.
  • Listed house, a few damaged bricks beside a window. Ask the builder to pause if listed building consent is needed.

Anyone in the UK can post or register. QuoteZila is a new, early-stage project, so replies depend on who has joined near you [QZ5]. Up to five matched local businesses can quote [QZ2]. QuoteZila is free for customers and local businesses [QZ1].

Questions about flaking bricks

Is a flaking brick the same as a damp problem?

Not by itself. The Planning Portal says a wall should resist moisture from the ground, which normally means a damp-proof course, and should resist weather from the outside. Brickwork generally gives good weather resistance on its own. A flaking face is a reason to ask whether those jobs are still being done, not proof of a single cause.

Do I need planning permission to repair flaking bricks?

The Planning Portal says you do not need to apply for planning permission for repairs, maintenance or minor improvements, such as painting a house. A listed building needs listed building consent for significant works, inside or outside. If the repair means cladding the wall, conservation areas and similar designated land have extra limits.

Can I rake the face off and paint it?

This page does not tell you to. Re-decorating the surface of an existing wall would not normally need building regulations approval, but renovation of a wall that counts as a thermal element can trigger a requirement to upgrade insulation. Cutting bricks out is a builder's decision, especially above head height.
