Is Gwent prone to ground movement?

What happens during lintel replacement, step by step?

  1. 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.

  2. 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.

  3. 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

  • Soft, crumbly timber visible behind the brick face over a bay
  • A diagonal crack climbing away from a window head
  • Rust stains or flaking steel showing above the frame

How we usually approach lintel replacement

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

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.

Questions about lintel replacement in Blackwood

Do you cover Blackwood?

Is the ground in Gwent prone to subsidence?

The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. 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.

Do I need building regulations approval to replace a lintel?

In England and Wales, replacing a lintel is structural work and building control will usually need to approve it. Rules differ in Scotland and Northern Ireland. We deal with building control where the work needs it, and include the cost in the quote.
