About our lintel replacement service in Farnworth
We cover lintel replacement in Farnworth (BL2, BL3, BL4) and the streets around it. Farnworth is around 2.7 miles from Bolton, and we cover both. Each job is designed by a structural engineer and approved through Bolton Council before work begins.
We survey the opening, arrange the engineer's specification and building control, prop the wall, swap the lintel and rebuild the masonry and plaster around it. Your quote is written and itemised, and it covers matching the bricks and mortar as closely as the existing wall allows.
Things to plan for
- 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.
- 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.
- 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.
- 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.
- Ground-floor lintels can usually be replaced from the ground with props alone. Openings on upper floors need scaffolding or a tower, which adds time and cost but also gives a safe, stable platform for rebuilding the brickwork neatly.
How the job runs in Farnworth
Survey in Farnworth
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 Bolton Council, 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 control and neighbours in Farnworth
For Farnworth, building control is provided by Bolton Council, 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.
Lintel replacement in Farnworth: your questions
Can you work on older or listed homes in Farnworth?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
How much does lintel replacement cost in Farnworth?
As a guide, budget £380–£1,150 per lintel including VAT for lintel replacement in Farnworth, based on published UK cost guides adjusted for prices in the North West (-4%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Will the new brickwork match the old?
We aim for a close match by reusing the original bricks wherever they come out cleanly and sourcing reclaimed or similar bricks for any shortfall. Mortar colour and type are chosen to suit the existing wall. New work can look slightly fresher at first and tends to weather in over time.
How long does lintel replacement take?
Most single openings take one to two working days on site, covering propping, removing the old lintel, fitting the new one and rebuilding the brickwork. Upper-floor lintels needing scaffolding, wide bay windows, and jobs where bricks must be sourced to match can all take longer.
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 happens at the survey visit in Farnworth?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
