Planning lintel replacement in Greenford

Planning lintel replacement in Greenford? Our team covers UB1, UB2, UB4, UB5 and UB6 and the streets around them. Our coverage runs across London, so nearby villages are included too. You get one written quote for the calculations, approvals, propping, steel and making good.

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

  • 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.
  • 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.
  • Diagonal cracks that start at the top corners of a window and step up through the mortar joints are a classic sign of a lintel problem. Movement elsewhere in a house can cause similar cracks, so the cause is confirmed on site before anything is replaced.
  • 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.
  • 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 Greenford 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 Greenford

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 the local council's building control team 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.

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 Greenford

How soon can lintel replacement start in Greenford?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.

Do you cover Greenford for lintel replacement?

Yes. We carry out lintel replacement in Greenford and the UB1, UB2, UB4, UB5 and UB6 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written 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.

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.

Is a cracked lintel dangerous?

It can become a problem if left, because the masonry above loses support and cracks tend to widen as it settles. Failure is usually gradual, but if bricks are loose, a frame is distorting or cracks are growing quickly, have it checked promptly and keep people clear of the area.

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

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.
