Lintel replacement in Southwark

A lintel problem in Southwark, as anywhere, usually shows first as a crack climbing from the corner of a window. We look at what is actually spanning the opening, whether timber, steel, concrete or brick, and what has made it fail.

Is Greater London prone to ground movement?

We cover the whole of Southwark, including postcode districts SE1, SE5, SE8, SE11, SE14; about 310,000 people live in the borough. We also take enquiries from nearby Lambeth (2 miles), Lewisham (3 miles) and Tower Hamlets (4 miles).

Shrinkable clay is widespread in Greater London. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Greater London: Victorian and Edwardian terraces with shallow footings, inter-war semis in the outer boroughs, and converted flats and mansion blocks.

What happens when we carry out lintel replacement in Southwark?

  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. 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.

  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

  • Window or door frames that have started to bind or distort
  • Brickwork above an opening visibly dipping in the middle
  • Damp patches on the inside wall just above a window

Which repair method suits a home in Southwark?

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

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.

Lintel replacement in Southwark: questions and answers

How much will lintel replacement cost in Southwark?

Guide prices for lintel replacement in Southwark start from about £940 per opening, including VAT, on London rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Southwark?

Yes, Southwark is covered, along with postcode districts SE1, SE5, SE8, SE11. We also cover nearby Lambeth and Lewisham.

Is the ground in Greater London prone to subsidence?

Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. Only an investigation can say why a particular building has moved.

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.
