Lintel replacement in Mid Glamorgan

Homes in Mid Glamorgan are mostly long stone and brick terraces on valley sides. That matters for lintel replacement: footings, wall construction and mortar all vary with the age of the building. Clay soils are found in parts of Mid Glamorgan.

What should you know about the ground under Mid Glamorgan?

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.

Historic coal workings are recorded beneath parts of Mid Glamorgan, and a coal mining search is worth checking where movement is unexplained. What you mostly find across Mid Glamorgan: long stone and brick terraces on valley sides, Victorian houses in Bridgend and post-war estates.

What happens when we carry out lintel replacement in Mid Glamorgan?

  1. 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.

  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.

Signs you may need lintel replacement

  • Rust stains or flaking steel showing above the frame
  • Brickwork above an opening visibly dipping in the middle
  • Damp patches on the inside wall just above a window
  • A diagonal crack climbing away from a window head

Which repair method suits a home in Mid Glamorgan?

Replacement with a cavity tray

A damp-proof membrane is laid over the new lintel with stop ends and weep holes, so water running down the cavity is directed out rather than into the house. Many older lintels were installed without one, which is often why they failed.

Best for: Cavity walls with damp above windows

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

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

Do you need approval 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.

Lintel replacement in Mid Glamorgan: questions and answers

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. Historic coal workings are recorded beneath parts of Mid Glamorgan, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.

How much will lintel replacement cost in Mid Glamorgan?

On Wales rates, lintel replacement starts from about £690 per opening, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

Can a lintel be replaced without removing the window?

Often yes. With the wall propped or needled, the old lintel can usually be cut out above the frame. If the frame has been carrying load or the lintel sits tight on it, the window may need removing and refitting, which we include in the quote.

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.

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.
