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.

Things to plan for

  • Bricks taken down are cleaned and reused where possible, and any shortfall is made up with reclaimed or close-matching bricks. Mortar is mixed to suit the colour and strength of the existing wall, which in older homes often means a lime mortar.
  • 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.
  • While the old lintel is out, the brickwork above sits on adjustable steel props with needles or masonry prop heads fixed through the mortar joints. The props stand on boards or spreaders so their load is shared across the ground or floor beneath.
  • The replacement is specified by a structural engineer, who looks at the opening width, the wall construction and what the lintel carries, such as floor joists, a bay roof or a gable. Solid walls and cavity walls usually call for different lintel types.
  • 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.

How the job runs in Redruth

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. Building control

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

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Redruth

Structural openings in English homes need building regulations approval before work starts. Cornwall 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.

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.

Local questions answered

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

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.

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

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.

How do I know if my lintel needs replacing?

Look for diagonal cracks rising from the top corners of a window or door, brick courses that dip over the opening, rust staining or flaking on a concrete lintel, and frames that have started to stick. Any of these is worth having checked, as the cause needs confirming on site before a replacement is planned.

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.

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.
