Which repair method suits a home in Royston?
Inner and outer lintel replacement
Solid walls and some cavity walls carry separate lintels on the inside and outside faces. Where both have failed, each is replaced in turn, keeping the wall supported throughout. Internal plaster and reveals are then made good and redecorated where included.
Best for: Older solid walls with rotten timber across the inner face
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
What happens when we carry out lintel replacement in Royston?
Support the wall
Props or needles are set so the brickwork above carries no load on the old lintel. Windows are protected or temporarily removed where the work demands it, and the room inside is sheeted against dust.
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.
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.
Lintel replacement in Royston: questions and answers
How much should I budget for lintel replacement in Royston?
Guide prices for lintel replacement in Royston start from about £790 per opening, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Royston?

Why do houses in Hertfordshire crack?
South Hertfordshire around Watford, Borehamwood and Potters Bar is London Clay, while the north and west are chalk with clay-with-flints and the east has boulder clay. The clay areas are prone to seasonal subsidence near trees. Only an investigation can say why a particular building has moved.
How long does it take to replace a lintel?
Most single lintels are replaced in one to two days. The props stay in until the mortar has gained enough strength, and wide bays or openings with both inner and outer lintels can take longer. The window can usually be used again once the supports come out.
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.
