Why does the ground in East Sussex matter for lintel replacement?
Brighton, East Sussex: about 280,000 residents across postcode districts BN1, BN2, BN3, BN41. We also take enquiries from nearby Shoreham-by-Sea (6 miles), Peacehaven (6 miles) and Lewes (7 miles).
East Sussex is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Across East Sussex, most homes are Regency and Victorian terraces on the coast, Wealden timber-framed houses, and inter-war bungalows and semis.
Symptoms that point to lintel replacement
- Damp patches on the inside wall just above a window
- A diagonal crack climbing away from a window head
- Window or door frames that have started to bind or distort

Methods for lintel replacement
Inner and outer lintel replacement
Solid walls and some cavity walls carry separate lintels on the inside and outside faces. Where both have failed, each is replaced in turn, keeping the wall supported throughout. Internal plaster and reveals are then made good and redecorated where included.
Best for: Older solid walls with rotten timber across the inner face
Propping and needling
Adjustable props carry the wall above while the old lintel comes out. For heavier walls, short steel needles are passed through holes cut above the opening and propped on both sides, taking the load off the lintel completely. The supports stay until the new work has set.
Best for: Openings with heavy walls, upper floors or bay windows above
From first photo to finished repair
Specify the replacement
We confirm the lintel type, length and bearing needed. For wide openings, bays or walls with unusual loads, an engineer may specify it, and where the repair needs an engineer’s design or sign-off we can arrange one.
Support the wall
Props or needles are set so the brickwork above carries no load on the old lintel. Windows are protected or temporarily removed where the work demands it, and the room inside is sheeted against dust.
Remove and replace
Brickwork is carefully taken out above the lintel, the old lintel removed and the new one bedded level on full bearings. A cavity tray goes in where relevant, then the brickwork above is relaid.
Rules for lintel replacement in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Frequently asked questions
How much should I budget for lintel replacement in Brighton?
Guide prices for lintel replacement in Brighton start from about £840 per opening, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Brighton?
Yes. We take enquiries from across Brighton, including BN1, BN2, BN3, BN41, and from nearby places such as Shoreham-by-Sea and Peacehaven. Send photos for a free initial view and we will tell you what happens next.
Why do houses in East Sussex crack?
Inland East Sussex is Weald Clay and Wealden sands, while the South Downs and the coast around Brighton and Eastbourne are chalk. The Weald Clay areas are prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.
What is a cavity tray and do I need one?
A cavity tray is a damp-proof membrane above a lintel that catches water running down inside a cavity wall and sends it out through weep holes. If your wall is cavity construction and the original lintel had no tray, fitting one with the new lintel is usually sensible.
How long does it take to replace a lintel?
Most single lintels are replaced in one to two days. The props stay in until the mortar has gained enough strength, and wide bays or openings with both inner and outer lintels can take longer. The window can usually be used again once the supports come out.
