Lintel replacement in Gainsborough
Bay windows on older houses around Gainsborough often hide a timber lintel behind the face brickwork. When that timber rots, the bay brickwork drops and cracks, and replacing it properly means supporting the wall above throughout the job.

How we usually approach lintel replacement
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
What happens during lintel replacement, step by step?
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.
What to look for before calling about lintel replacement

Rules for lintel replacement in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Questions about lintel replacement in Gainsborough
What is the price of lintel replacement in Gainsborough?
Guide prices for lintel replacement in Gainsborough start from about £735 per opening, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out lintel replacement in Gainsborough?
Yes, Gainsborough is covered, along with postcode districts DN21. We also cover nearby Retford and Scunthorpe.
Does the ground around Gainsborough cause cracking?
Lincolnshire has Lias, Oxford and Kimmeridge clays on the vales, chalk on the Wolds and soft silts and peat in the fens around Boston and Spalding. Fen ground and clay can both settle or shrink in dry years. Only an investigation can say why a particular building has moved.
How do I know if a lintel has failed?
The most common sign is a diagonal or stepped crack running up from the top corner of a window or door. Others include a dip in the brickwork above, rust or rot visible at the lintel edge, and windows that start to stick. A crack alone can have other causes, so it is worth checking.
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.
