How do local ground conditions affect lintel replacement in Tonbridge?

Tonbridge (TN9, TN10, TN11) has around 36,000 residents and sits in Kent. If you are just outside Tonbridge, we also cover Tunbridge Wells (4 miles), Sevenoaks (6 miles) and Crowborough (10 miles).

Much of Kent sits on clay that shrinks in dry summers and swells in wet winters. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.

Methods for lintel replacement

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

Inner and outer lintel replacement

Solid walls and some cavity walls carry separate lintels on the inside and outside faces. Where both have failed, each is replaced in turn, keeping the wall supported throughout. Internal plaster and reveals are then made good and redecorated where included.

Best for: Older solid walls with rotten timber across the inner face

From first photo to finished repair

  1. Inspect the opening

    We look at the crack pattern, the type of lintel and what sits above it. Pictures of both faces of the window, plus any visible lintel edge, help us judge it before visiting.

  2. 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.

  3. Support the wall

    Props or needles are set so the brickwork above carries no load on the old lintel. Windows are protected or temporarily removed where the work demands it, and the room inside is sheeted against dust.

Symptoms that point to lintel replacement

  • Brickwork above an opening visibly dipping in the middle
  • A diagonal crack climbing away from a window head
  • Damp patches on the inside wall just above a window

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.

Frequently asked questions

How much will lintel replacement cost in Tonbridge?

Guide prices for lintel replacement in Tonbridge 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 cover Tonbridge?

Yes, Tonbridge is covered, along with postcode districts TN9, TN10, TN11. We also cover nearby Tunbridge Wells and Sevenoaks.

Is the ground in Kent prone to subsidence?

North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. Only an investigation can say why a particular building has moved.

Do I need building regulations approval to replace a lintel?

In England and Wales, replacing a lintel is structural work and building control will usually need to approve it. Rules differ in Scotland and Northern Ireland. We deal with building control where the work needs it, and include the cost in the quote.

How do I know if a lintel has failed?

The most common sign is a diagonal or stepped crack running up from the top corner of a window or door. Others include a dip in the brickwork above, rust or rot visible at the lintel edge, and windows that start to stick. A crack alone can have other causes, so it is worth checking.
