What happens when we carry out lintel replacement in Chesham?
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 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.
Signs you may need lintel replacement
- Window or door frames that have started to bind or distort
- Rust stains or flaking steel showing above the frame
- Brickwork above an opening visibly dipping in the middle

Which repair method suits a home in Chesham?
Like-for-like replacement
The failed lintel comes out and one of suitable type and size is bedded on mortar with adequate bearing at each end. Bricks above are relaid to match the original bond and the joints are pointed to blend with the surrounding wall.
Best for: Standard windows and doors with a single failed lintel
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
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 Chesham: questions and answers
What is the price of lintel replacement in Chesham?
Guide prices for lintel replacement in Chesham 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 Chesham?
Yes, Chesham is covered, along with postcode districts HP5. We also cover nearby Amersham and Berkhamsted.
Does the ground around Chesham cause cracking?
The Chilterns are chalk with clay-with-flints on the tops, while the Vale of Aylesbury and Milton Keynes sit on Gault, Kimmeridge and Oxford Clays and glacial till. The vale clays are prone to seasonal shrinkage near trees. 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.
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.
