What lintel replacement involves in Crowthorne

For homes in Crowthorne and the RG40 and RG45 districts, we handle lintel replacement from survey to sign-off. We also work in nearby Reading, roughly 9.7 miles away. The beam is sized by a structural engineer and inspected before it is boxed in.

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

  • 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.
  • 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.
  • 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.
  • 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.

How the job runs in Crowthorne

  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 Wokingham Borough 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.

Building rules for Crowthorne

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Wokingham Borough Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

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.

Questions about lintel replacement in Crowthorne

Can you work on older or listed homes in Crowthorne?

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.

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.

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.

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.
