Lintel replacement in Wallington: how it works

Wallington has a mix of housing, and lintel replacement needs a slightly different approach in each. Our coverage runs across London, so nearby villages are included too. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

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.

Things to plan for

  • 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.
  • 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.
  • Cables for outside lights, burglar alarms and doorbells often run just above window and door heads. These are noted at the survey and made safe by an electrician before the brickwork is opened up, then reinstated afterwards.

How the job runs in Wallington

  1. Free visit

    A short visit to Wallington 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 control and neighbours in Wallington

For Wallington, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

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 Wallington

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

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.

What happens at the survey visit in Wallington?

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.

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.

Can a timber lintel in an old house be replaced with steel or concrete?

Yes, where the engineer is satisfied it suits the wall. Timber lintels in older solid-walled homes are often swapped for a steel or concrete alternative that will not rot. The engineer considers how the wall is built, and where lime mortar is present the rebuild uses a compatible mortar.

What type of lintel will be fitted?

The engineer decides, based on the opening width, the wall construction and the load above. Steel lintels are common in cavity walls, while solid walls or wide openings may suit a different type or a steel section. We fit what the specification calls for rather than a one-size option.

How much does lintel replacement cost in Wallington?

As a guide, budget £510–£1,540 per lintel including VAT for lintel replacement in Wallington, based on published UK cost guides adjusted for London prices (+28%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
