Lintel replacement in Durham: how it works

Our lintel replacement service in Durham covers everything from the first visit to the completion paperwork. We also work in nearby Sunderland, roughly 11.7 miles away. Postcode districts we cover here include DH1.

We survey the opening, arrange the engineer's specification and building control, prop the wall, swap the lintel and rebuild the masonry and plaster around it. Your quote is written and itemised, and it covers matching the bricks and mortar as closely as the existing wall allows.

Key points for your project

  • Bay windows often rely on a timber beam, sometimes called a bressummer, across the front of the bay. When it rots, the bay roof and the brickwork over it can drop, and the engineer may specify a steel replacement instead.
  • A typical single lintel takes a day or two on site. Keep the building control completion certificate with your property papers, because buyers' surveyors often notice old cracking around openings and their solicitors will ask what was done about it.
  • Ground-floor lintels can usually be replaced from the ground with props alone. Openings on upper floors need scaffolding or a tower, which adds time and cost but also gives a safe, stable platform for rebuilding the brickwork neatly.
  • In cavity walls, a cavity tray and weep vents above the lintel send any water in the cavity back outside. Missing trays are a frequent cause of damp patches above window heads, so they are fitted as part of the replacement.
  • Windows and doors can often stay in place during a lintel replacement, keeping the house secure and weathertight. Where a frame has been carrying sagging brickwork for some time, it may need adjusting or replacing once the new lintel takes the load.

What happens, step by step

  1. Survey in Durham

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

    We submit a building notice or full plans application to Durham County Council, so approval is in place before the wall is touched.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Durham

Structural openings in English homes need building regulations approval before work starts. Durham County Council can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered

Can I stay at home while the work is done in Durham?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

Can you work on older or listed homes in Durham?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

Can a lintel be replaced without removing the window?

Often, yes. The brickwork above is propped, the old lintel is taken out and the new one fitted while the frame stays in place under protection. If the frame has been carrying weight because the old lintel sagged, it may need easing or adjusting once the new lintel is in.

Will the new brickwork match the old?

We aim for a close match by reusing the original bricks wherever they come out cleanly and sourcing reclaimed or similar bricks for any shortfall. Mortar colour and type are chosen to suit the existing wall. New work can look slightly fresher at first and tends to weather in over time.

Do I need building regulations approval to replace a lintel?

Usually yes, because a lintel is a structural element and replacing it is generally treated as building work. In England and Wales building control is notified or approved first, Scotland needs a building warrant before structural work starts, and Northern Ireland needs an application to council building control. We deal with this as part of the job.

Do you also work near Durham?

Yes. We also cover nearby towns including Chester-le-Street, Houghton-Le-Spring, Stanley and Washington.
