What lintel replacement involves in Mid and East Antrim
Lintel replacement is the removal of a failed beam above a window, door or other opening and its replacement with a new lintel specified by a structural engineer. The masonry above is held on temporary supports while the old lintel comes out, the new one is bedded level on sound bearings, and the brickwork and plaster around it are rebuilt and made good.
Across Mid and East Antrim, lintel replacement usually comes up when people want more light, a better layout or a way through to a new extension. That includes Ballymena, Larne and Carrickfergus, plus smaller towns and villages nearby. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Worth knowing before you start
- 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.
- 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.
- 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.
- In cavity walls, a cavity tray and weep vents above the lintel send any water in the cavity back outside. Missing trays are a frequent cause of damp patches above window heads, so they are fitted as part of the replacement.
- 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.

Lintel replacement by town
Lintel replacement in Mid and East Antrim: your questions
Which towns in Mid and East Antrim do you cover?
We cover towns including Carrickfergus, Ballymena and Larne, plus the villages and smaller towns around them.
Do I need a party wall agreement for lintel replacement in Mid and East Antrim?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
Why is my concrete lintel cracking and flaking?
Usually because the steel reinforcement inside has rusted. Rust takes up more space than steel, so it pushes the concrete cover off, exposing more steel to damp and speeding up the damage. An engineer checks whether the lintel can still do its job, but in many cases replacement is the sensible fix.
What type of lintel will be fitted?
The engineer decides, based on the opening width, the wall construction and the load above. Steel lintels are common in cavity walls, while solid walls or wide openings may suit a different type or a steel section. We fit what the specification calls for rather than a one-size option.
Will the new brickwork match the old?
We aim for a close match by reusing the original bricks wherever they come out cleanly and sourcing reclaimed or similar bricks for any shortfall. Mortar colour and type are chosen to suit the existing wall. New work can look slightly fresher at first and tends to weather in over time.
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.
Can I stay at home while the work is done in Mid and East Antrim?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
