About our lintel replacement service in Lancashire
Lintel replacement is the removal of a failed beam above a window, door or other opening and its replacement with a new lintel specified by a structural engineer. The masonry above is held on temporary supports while the old lintel comes out, the new one is bedded level on sound bearings, and the brickwork and plaster around it are rebuilt and made good.
Homes across Lancashire range from Victorian terraces to post-war semis and newer estates, and lintel replacement looks different in each. Towns we cover include Chorley, Blackpool and Skelmersdale, among other places in the area. We plan the steel, the temporary support and the approvals around the building, then fix the price in writing once the scope is agreed.
Key points for your project
- Older steel lintels and bare steel angles can corrode where water sits on them. Rust takes up more room than the steel it comes from, so a corroding lintel can lift the brick course above it and open up horizontal cracks.
- Concrete lintels fail when the steel reinforcement inside rusts and swells, pushing off the concrete face. Rust staining, flaking edges and exposed bars are the warning signs, and once that process is well under way an engineer will often recommend replacement over patching.
- A typical single lintel takes a day or two on site. Keep the building control completion certificate with your property papers, because buyers' surveyors often notice old cracking around openings and their solicitors will ask what was done about it.
- Diagonal cracks that start at the top corners of a window and step up through the mortar joints are a classic sign of a lintel problem. Movement elsewhere in a house can cause similar cracks, so the cause is confirmed on site before anything is replaced.
- Bay windows often rely on a timber beam, sometimes called a bressummer, across the front of the bay. When it rots, the bay roof and the brickwork over it can drop, and the engineer may specify a steel replacement instead.
From survey to sign-off in Lancashire
Survey in Lancashire
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building rules for Lancashire
For Lancashire, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Questions about lintel replacement in Lancashire
Who approves lintel replacement in Lancashire?
Structural work in Lancashire needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Can I stay at home while the work is done in Lancashire?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
Do I need scaffolding to replace a lintel?
For ground-floor windows and doors, usually not, as props and a stable platform from the ground are enough. First-floor and higher openings normally need scaffolding or a tower so the brickwork can be rebuilt safely, and that cost appears as its own line in the quote.
Can a lintel be replaced without removing the window?
Often, yes. The brickwork above is propped, the old lintel is taken out and the new one fitted while the frame stays in place under protection. If the frame has been carrying weight because the old lintel sagged, it may need easing or adjusting once the new lintel is in.
Can a timber lintel in an old house be replaced with steel or concrete?
Yes, where the engineer is satisfied it suits the wall. Timber lintels in older solid-walled homes are often swapped for a steel or concrete alternative that will not rot. The engineer considers how the wall is built, and where lime mortar is present the rebuild uses a compatible mortar.
What type of lintel will be fitted?
The engineer decides, based on the opening width, the wall construction and the load above. Steel lintels are common in cavity walls, while solid walls or wide openings may suit a different type or a steel section. We fit what the specification calls for rather than a one-size option.
How soon can lintel replacement start in Lancashire?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
