What lintel replacement involves in Farnham
If you live in Farnham, lintel replacement can usually be planned and priced after a single survey visit. It sits about 12.7 miles from Woking, which we also cover. We cover GU9 and GU10, and we fix the price in writing once the layout and scope are agreed.
A lintel is the short beam that carries the brickwork over a window or door. When it fails, the signs tend to show outside first: a crack stepping up from the corner of the frame, a dip in the brick courses, or a window that has started to bind. Timber, concrete and old steel lintels each fail in their own way, but the fix follows the same principle.
Things to plan for
- Replacing a structural lintel is generally treated as building work, so approval is in place before it starts. In England, Wales and Northern Ireland that means building control, and in Scotland a building warrant is needed before structural work begins.
- Bricks taken down are cleaned and reused where possible, and any shortfall is made up with reclaimed or close-matching bricks. Mortar is mixed to suit the colour and strength of the existing wall, which in older homes often means a lime mortar.
- 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.
- The replacement is specified by a structural engineer, who looks at the opening width, the wall construction and what the lintel carries, such as floor joists, a bay roof or a gable. Solid walls and cavity walls usually call for different lintel types.
- Windows and doors can often stay in place during a lintel replacement, keeping the house secure and weathertight. Where a frame has been carrying sagging brickwork for some time, it may need adjusting or replacing once the new lintel takes the load.
From survey to sign-off in Farnham
Survey in Farnham
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 control and neighbours in Farnham
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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 Farnham
Can I stay at home while the work is done in Farnham?
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.
How much does lintel replacement cost in Farnham?
As a guide, budget £450–£1,340 per lintel including VAT for lintel replacement in Farnham, based on published UK cost guides adjusted for prices in the South East (+12%). 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.
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.
Is a cracked lintel dangerous?
It can become a problem if left, because the masonry above loses support and cracks tend to widen as it settles. Failure is usually gradual, but if bricks are loose, a frame is distorting or cracks are growing quickly, have it checked promptly and keep people clear of the area.
Why is my concrete lintel cracking and flaking?
Usually because the steel reinforcement inside has rusted. Rust takes up more space than steel, so it pushes the concrete cover off, exposing more steel to damp and speeding up the damage. An engineer checks whether the lintel can still do its job, but in many cases replacement is the sensible fix.
Do I need a party wall agreement for lintel replacement in Farnham?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
