Lintel replacement in Bristol
Across Bristol, requests for lintel replacement usually begin with a crack someone has noticed getting wider. Clay soils are found in parts of Bristol. A repair only lasts if the reason for the movement has stopped.

Why does the ground in Bristol matter for lintel replacement?
Bristol has mixed ground: Mercia Mudstone, limestone and alluvium along the Avon, and Coal Measures under parts of the north and east of the city, where historic shallow workings are recorded. Made ground on old quarry and dock land is also common.
Parts of Bristol lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Bristol, most homes are Georgian and Victorian terraces on steep streets, inter-war council estates and post-war system-built homes.
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 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.

Repair options we may recommend
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
Like-for-like replacement
The failed lintel comes out and one of suitable type and size is bedded on mortar with adequate bearing at each end. Bricks above are relaid to match the original bond and the joints are pointed to blend with the surrounding wall.
Best for: Standard windows and doors with a single failed lintel
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
Do you need approval 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
Why do houses in Bristol crack?
Bristol has mixed ground: Mercia Mudstone, limestone and alluvium along the Avon, and Coal Measures under parts of the north and east of the city, where historic shallow workings are recorded. Made ground on old quarry and dock land is also common. Parts of Bristol lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will lintel replacement cost in Bristol?
On South West rates, lintel replacement starts from about £770 per opening, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
Can a lintel be replaced without removing the window?
Often yes. With the wall propped or needled, the old lintel can usually be cut out above the frame. If the frame has been carrying load or the lintel sits tight on it, the window may need removing and refitting, which we include in the quote.
How long does it take to replace a lintel?
Most single lintels are replaced in one to two days. The props stay in until the mortar has gained enough strength, and wide bays or openings with both inner and outer lintels can take longer. The window can usually be used again once the supports come out.
