What happens when we carry out lintel replacement in Caerphilly?
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.
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.
Signs you may need lintel replacement
- Window or door frames that have started to bind or distort

Which repair method suits a home in Caerphilly?
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

Why do houses in Mid Glamorgan crack?
Mid Glamorgan lies on the South Wales coalfield, with dense historic workings, spoil tips and steep valley sides. Landslip, retaining walls and mining legacy are all live issues in the valleys. 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.
