Lintel replacement in Derbyshire

We arrange surveys and price lintel replacement throughout Derbyshire. Parts of Derbyshire have clay that can shrink near trees in dry spells, and we take that into account before recommending a method.

Why does the ground in Derbyshire matter for lintel replacement?

East Derbyshire, including Chesterfield, Ilkeston and Heanor, lies on the Coal Measures with a long history of shallow and deep coal mining. The Peak District to the west is limestone and gritstone, and Derby itself sits largely on Mercia Mudstone.

Parts of Derbyshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Derbyshire: brick terraces in former mining towns, gritstone cottages in the Peak, and inter-war and post-war semis.

From first photo to finished repair

  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. 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.

  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.

Symptoms that point to lintel replacement

  • Brickwork above an opening visibly dipping in the middle
  • Damp patches on the inside wall just above a window
  • Soft, crumbly timber visible behind the brick face over a bay
  • Rust stains or flaking steel showing above the frame

Methods for lintel replacement

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

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

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

Do you need approval 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.

Frequently asked questions

Is the ground in Derbyshire prone to subsidence?

East Derbyshire, including Chesterfield, Ilkeston and Heanor, lies on the Coal Measures with a long history of shallow and deep coal mining. The Peak District to the west is limestone and gritstone, and Derby itself sits largely on Mercia Mudstone. Parts of Derbyshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will lintel replacement cost in Derbyshire?

On East Midlands rates, lintel replacement starts from about £735 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.

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.

What is a cavity tray and do I need one?

A cavity tray is a damp-proof membrane above a lintel that catches water running down inside a cavity wall and sends it out through weep holes. If your wall is cavity construction and the original lintel had no tray, fitting one with the new lintel is usually sensible.
