Repair options we may recommend

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

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

What to expect when we carry out lintel replacement

Inspect the opening
We look at the crack pattern, the type of lintel and what sits above it. Pictures of both faces of the window, plus any visible lintel edge, help us judge it before visiting.
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.

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.

Your lintel replacement questions

How much should I budget for lintel replacement in St Austell?

Why do houses in Cornwall crack?

Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there. 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.

What does needling a wall mean?

Needling means passing short steel members through holes cut in the wall just above the opening and supporting them on props on both sides. The needles take the weight of the wall above, so the old lintel can be removed safely without any brickwork dropping.
