About our lintel replacement service in Oxfordshire
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.
Looking for lintel replacement in Oxfordshire? Coverage takes in Witney, Oxford and Abingdon and everywhere in between. Our teams handle the calculations, the building control approval, the propping and the steel itself, and leave the opening ready for plastering and decoration.
What to expect
- Many Victorian and Edwardian houses have a timber lintel hidden behind a decorative brick arch or on the inner face of the wall. Damp from leaking gutters or failed pointing can rot it unseen until the brickwork above starts to drop.
- 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.
- 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.
- 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.
- In cavity walls, a cavity tray and weep vents above the lintel send any water in the cavity back outside. Missing trays are a frequent cause of damp patches above window heads, so they are fitted as part of the replacement.
How the job runs in Oxfordshire
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
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.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Oxfordshire
For Oxfordshire, 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.
Lintel replacement in Oxfordshire: your questions
Can you work on older or listed homes in Oxfordshire?
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.
Can I stay at home while the work is done in Oxfordshire?
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.
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.
How do I know if my lintel needs replacing?
Look for diagonal cracks rising from the top corners of a window or door, brick courses that dip over the opening, rust staining or flaking on a concrete lintel, and frames that have started to stick. Any of these is worth having checked, as the cause needs confirming on site before a replacement is planned.
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.
What happens at the survey visit in Oxfordshire?
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.
