Lintel replacement in Allerton
Bay windows on older houses around Allerton 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.

Why does the ground in Merseyside matter for lintel replacement?
Allerton, Merseyside: about 16,000 residents across postcode districts L18, L19, L25. Neighbouring towns we cover: Huyton (4 miles), Liverpool (5 miles) and Bebington (5 miles).
Merseyside has a mix of ground, with clay in some places and firmer rock in others. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Merseyside, most homes are Victorian terraces and villas, inter-war council estates and post-war semis.
Methods for lintel replacement
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
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.
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.
Symptoms that point to lintel replacement
- Damp patches on the inside wall just above a window
- Brickwork above an opening visibly dipping in the middle
- Soft, crumbly timber visible behind the brick face over a bay

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
What is the price of lintel replacement in Allerton?
Guide prices for lintel replacement in Allerton start from about £720 per opening, including VAT, on North West 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 Allerton?
We do. Allerton and the surrounding area are covered, including nearby Huyton and Liverpool. A free initial assessment from your photos is the first step.
Does the ground around Allerton cause cracking?
Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. Only an investigation can say why a particular building has moved.
How long does it take to replace a lintel?
Most single lintels are replaced in one to two days. The props stay in until the mortar has gained enough strength, and wide bays or openings with both inner and outer lintels can take longer. The window can usually be used again once the supports come out.
Is it safe to live in the house during lintel replacement?
Yes, in almost all cases. The wall is fully supported before anything is removed, and the work is confined to one opening at a time. The affected room is sheeted against dust and kept clear while props are in place.
