Is Lancashire prone to ground movement?
With roughly 17,000 people, Heysham spans postcode districts LA3, LA4 in Lancashire. Neighbouring towns we cover: Morecambe (2 miles), Lancaster (4 miles) and Fleetwood (9 miles).
Lancashire has a mix of ground, with clay in some places and firmer rock in others. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause.

Which repair method suits a home in Heysham?
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 when we carry out lintel replacement in Heysham?
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.
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 Heysham: questions and answers
How much will lintel replacement cost in Heysham?
Guide prices for lintel replacement in Heysham 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.

Yes. We take enquiries from across Heysham, including LA3, LA4, and from nearby places such as Morecambe and Lancaster. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Lancashire prone to subsidence?
Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns. 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.
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.
