Lintel replacement in Banstead
Bay windows on older houses around Banstead often hide a timber lintel behind the face brickwork. When that timber rots, the bay brickwork drops and cracks, and replacing it properly means supporting the wall above throughout the job.

How do local ground conditions affect lintel replacement in Banstead?
We cover Banstead and its postcode districts KT17, SM2, SM7, part of Surrey, with a population of roughly 46,000. Nearby places we cover include Ewell (3 miles), Sutton (3 miles) and Croydon (6 miles).
Much of Surrey sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Surrey: Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.
How we usually approach 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
What happens during lintel replacement, step by step?
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.
Remove supports and make good
Once the mortar has gained strength, props and needles come out and their holes are made good. Pointing, reveals and plaster are finished, and the window is refitted or checked for smooth operation.
What to look for before calling about lintel replacement

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.
Questions about lintel replacement in Banstead
What is the price of lintel replacement in Banstead?
Guide prices for lintel replacement in Banstead 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.
Do you carry out lintel replacement in Banstead?
Yes, Banstead is covered, along with postcode districts KT17, SM2, SM7. We also cover nearby Ewell and Sutton.
Does the ground around Banstead cause cracking?
North Surrey sits on London Clay, the south on Weald Clay, with chalk along the North Downs and sands in the west. Large gardens with mature trees on clay make seasonal subsidence a familiar problem. 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.
What does needling a wall mean?
Needling means passing short steel members through holes cut in the wall just above the opening and supporting them on props on both sides. The needles take the weight of the wall above, so the old lintel can be removed safely without any brickwork dropping.
