What happens when we carry out lintel replacement in Sleaford?
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.
Signs you may need lintel replacement
- Soft, crumbly timber visible behind the brick face over a bay
- A diagonal crack climbing away from a window head
- Rust stains or flaking steel showing above the frame

Which repair method suits a home in Sleaford?
Replacement with a cavity tray
A damp-proof membrane is laid over the new lintel with stop ends and weep holes, so water running down the cavity is directed out rather than into the house. Many older lintels were installed without one, which is often why they failed.
Best for: Cavity walls with damp above windows
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
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.
Lintel replacement in Sleaford: questions and answers
How much will lintel replacement cost in Sleaford?

Is the ground in Lincolnshire prone to subsidence?
Lincolnshire has Lias, Oxford and Kimmeridge clays on the vales, chalk on the Wolds and soft silts and peat in the fens around Boston and Spalding. Fen ground and clay can both settle or shrink in dry years. Only an investigation can say why a particular building has moved.
How do I know if a lintel has failed?
The most common sign is a diagonal or stepped crack running up from the top corner of a window or door. Others include a dip in the brickwork above, rust or rot visible at the lintel edge, and windows that start to stick. A crack alone can have other causes, so it is worth checking.
Do I need building regulations approval to replace a lintel?
In England and Wales, replacing a lintel is structural work and building control will usually need to approve it. Rules differ in Scotland and Northern Ireland. We deal with building control where the work needs it, and include the cost in the quote.
