Planning lintel replacement in Wembley

Our lintel replacement service in Wembley covers everything from the first visit to the completion paperwork. Our coverage runs across London, so nearby villages are included too. Postcode districts we cover here include HA0, HA1, HA3, HA9 and NW10.

A lintel is the short beam that carries the brickwork over a window or door. When it fails, the signs tend to show outside first: a crack stepping up from the corner of the frame, a dip in the brick courses, or a window that has started to bind. Timber, concrete and old steel lintels each fail in their own way, but the fix follows the same principle.

What to expect

  • 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.
  • Concrete lintels fail when the steel reinforcement inside rusts and swells, pushing off the concrete face. Rust staining, flaking edges and exposed bars are the warning signs, and once that process is well under way an engineer will often recommend replacement over patching.
  • Many Victorian and Edwardian houses have a timber lintel hidden behind a decorative brick arch or on the inner face of the wall. Damp from leaking gutters or failed pointing can rot it unseen until the brickwork above starts to drop.
  • Older steel lintels and bare steel angles can corrode where water sits on them. Rust takes up more room than the steel it comes from, so a corroding lintel can lift the brick course above it and open up horizontal cracks.
  • 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.

What happens, step by step

  1. Free visit

    A short visit to Wembley to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building rules for Wembley

Structural openings in English homes need building regulations approval before work starts. The local council's building control team 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.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about lintel replacement in Wembley

Do you cover Wembley for lintel replacement?

Yes. We carry out lintel replacement in Wembley and the HA0, HA1, HA3, HA9 and NW10 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

What happens at the survey visit in Wembley?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

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 scaffolding to replace a lintel?

For ground-floor windows and doors, usually not, as props and a stable platform from the ground are enough. First-floor and higher openings normally need scaffolding or a tower so the brickwork can be rebuilt safely, and that cost appears as its own line in the quote.

How long does lintel replacement take?

Most single openings take one to two working days on site, covering propping, removing the old lintel, fitting the new one and rebuilding the brickwork. Upper-floor lintels needing scaffolding, wide bay windows, and jobs where bricks must be sourced to match can all take longer.

Do I need a party wall agreement for lintel replacement in Wembley?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
