Lintel replacement in Crawley

Bay windows on older houses around Crawley often hide a timber lintel behind the face brickwork. When that timber rots, the bay brickwork drops and cracks, and replacing it properly means supporting the wall above throughout the job.

What should you know about the ground under Crawley?

Crawley (RH10, RH11) has around 120,000 residents and sits in West Sussex. Nearby places we cover include Horley (4 miles), Horsham (7 miles) and East Grinstead (8 miles).

Shrinkable clay is widespread in West Sussex. Ground movement here is more often linked to soils, drains and trees than to mining. Across West Sussex, most homes are Wealden cottages, 1930s semis and bungalows on the coast, and new-town estates in Crawley.

What happens during lintel replacement, step by step?

  1. Specify the replacement

    We confirm the lintel type, length and bearing needed. For wide openings, bays or walls with unusual loads, an engineer may specify it, and where the repair needs an engineer’s design or sign-off we can arrange one.

  2. Remove and replace

    Brickwork is carefully taken out above the lintel, the old lintel removed and the new one bedded level on full bearings. A cavity tray goes in where relevant, then the brickwork above is relaid.

  3. Remove supports and make good

    Once the mortar has gained strength, props and needles come out and their holes are made good. Pointing, reveals and plaster are finished, and the window is refitted or checked for smooth operation.

What to look for before calling about lintel replacement

  • Window or door frames that have started to bind or distort
  • Damp patches on the inside wall just above a window
  • Soft, crumbly timber visible behind the brick face over a bay

How we usually approach lintel replacement

Propping and needling

Adjustable props carry the wall above while the old lintel comes out. For heavier walls, short steel needles are passed through holes cut above the opening and propped on both sides, taking the load off the lintel completely. The supports stay until the new work has set.

Best for: Openings with heavy walls, upper floors or bay windows above

Replacement with a cavity tray

A damp-proof membrane is laid over the new lintel with stop ends and weep holes, so water running down the cavity is directed out rather than into the house. Many older lintels were installed without one, which is often why they failed.

Best for: Cavity walls with damp above windows

Rules for lintel replacement in England

In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Questions about lintel replacement in Crawley

What is the price of lintel replacement in Crawley?

Guide prices for lintel replacement in Crawley start from about £840 per opening, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you carry out lintel replacement in Crawley?

Yes, Crawley is covered, along with postcode districts RH10, RH11. We also cover nearby Horley and Horsham.

Does the ground around Crawley cause cracking?

North West Sussex around Crawley and Horsham sits on Weald Clay, the South Downs are chalk, and the coastal plain has brickearth and gravels. The Weald Clay is prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.

Is it safe to live in the house during lintel replacement?

Yes, in almost all cases. The wall is fully supported before anything is removed, and the work is confined to one opening at a time. The affected room is sheeted against dust and kept clear while props are in place.

What does needling a wall mean?

Needling means passing short steel members through holes cut in the wall just above the opening and supporting them on props on both sides. The needles take the weight of the wall above, so the old lintel can be removed safely without any brickwork dropping.
