Lintel replacement in Canterbury
A lintel problem in Canterbury, as anywhere, usually shows first as a crack climbing from the corner of a window. We look at what is actually spanning the opening, whether timber, steel, concrete or brick, and what has made it fail.

How do local ground conditions affect lintel replacement in Canterbury?
Canterbury is in Kent and takes in postcode districts CT1, CT2, CT5, CT6. About 55,000 people live there. Nearby places we cover include Whitstable (6 miles), Herne Bay (7 miles) and Faversham (9 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. Typical buildings in Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.

Repair options we may recommend
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
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
What to expect when we carry out lintel replacement
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.
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.
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.
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.
Your lintel replacement questions
How much will lintel replacement cost in Canterbury?
Guide prices for lintel replacement in Canterbury 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 Canterbury?
Yes, Canterbury is covered, along with postcode districts CT1, CT2, CT5, CT6. We also cover nearby Whitstable and Herne Bay.
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.
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 is a cavity tray and do I need one?
A cavity tray is a damp-proof membrane above a lintel that catches water running down inside a cavity wall and sends it out through weep holes. If your wall is cavity construction and the original lintel had no tray, fitting one with the new lintel is usually sensible.
