What to expect when we carry out lintel replacement
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.
Remove supports and make good
Once the mortar has gained strength, props and needles come out and their holes are made good. Pointing, reveals and plaster are finished, and the window is refitted or checked for smooth operation.

Repair options we may recommend
Like-for-like replacement
The failed lintel comes out and one of suitable type and size is bedded on mortar with adequate bearing at each end. Bricks above are relaid to match the original bond and the joints are pointed to blend with the surrounding wall.
Best for: Standard windows and doors with a single failed lintel
Propping and needling
Adjustable props carry the wall above while the old lintel comes out. For heavier walls, short steel needles are passed through holes cut above the opening and propped on both sides, taking the load off the lintel completely. The supports stay until the new work has set.
Best for: Openings with heavy walls, upper floors or bay windows above
Rules for lintel replacement in Wales
In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.
Your lintel replacement questions
How much will lintel replacement cost in Penarth?
Guide prices for lintel replacement in Penarth start from about £690 per opening, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Penarth?
We do. Penarth and the surrounding area are covered, including nearby Cardiff and Barry. A free initial assessment from your photos is the first step.
Is the ground in South Glamorgan prone to subsidence?
Cardiff is built on Mercia Mudstone, river gravels and alluvium, and the Vale of Glamorgan on Lias limestone and clay. Soft alluvium near the rivers and docks can settle. Only an investigation can say why a particular building has moved.
Is it safe to live in the house during lintel replacement?
Yes, in almost all cases. The wall is fully supported before anything is removed, and the work is confined to one opening at a time. The affected room is sheeted against dust and kept clear while props are in place.
What is a cavity tray and do I need one?
A cavity tray is a damp-proof membrane above a lintel that catches water running down inside a cavity wall and sends it out through weep holes. If your wall is cavity construction and the original lintel had no tray, fitting one with the new lintel is usually sensible.
