What you mostly find across Derbyshire: brick terraces in former mining towns, gritstone cottages in the Peak, and inter-war and post-war semis.

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
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
What happens during lintel replacement, step by step?
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.
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 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.
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 Derby
How much should I budget for lintel replacement in Derby?
Guide prices for lintel replacement in Derby start from about £735 per opening, including VAT, on East Midlands 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 Derby?
Yes, Derby is covered, along with postcode districts DE1, DE22, DE23. We also cover nearby Belper and Ilkeston.
Why do houses in Derbyshire crack?
East Derbyshire, including Chesterfield, Ilkeston and Heanor, lies on the Coal Measures with a long history of shallow and deep coal mining. The Peak District to the west is limestone and gritstone, and Derby itself sits largely on Mercia Mudstone. 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.
