Is Kent prone to ground movement?
Longfield (DA3, DA4, DA13) has around 17,000 residents and sits in Kent. Nearby places we cover include Swanscombe (3 miles), Gravesend (4 miles) and Dartford (5 miles).
Kent is one of the parts of the UK where clay soils are most likely to move with the seasons. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.
Methods for lintel replacement
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
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
From first photo to finished repair
Inspect the opening
We look at the crack pattern, the type of lintel and what sits above it. Pictures of both faces of the window, plus any visible lintel edge, help us judge it before visiting.
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.
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.
Symptoms that point to lintel replacement
- Damp patches on the inside wall just above a window

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 Longfield?
Guide prices for lintel replacement in Longfield 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 Longfield?
We do. Longfield and the surrounding area are covered, including nearby Swanscombe and Gravesend. A free initial assessment from your photos is the first step.
Why do houses in Kent crack?
North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. Only an investigation can say why a particular building has moved.
Can a lintel be replaced without removing the window?
Often yes. With the wall propped or needled, the old lintel can usually be cut out above the frame. If the frame has been carrying load or the lintel sits tight on it, the window may need removing and refitting, which we include in the quote.
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.
