What should you know about the ground under Coleraine?
Coleraine is in County Londonderry and takes in postcode districts BT52. About 26,000 people live there. Neighbouring towns we cover: Ballymoney (7 miles), Limavady (13 miles) and Ballymena (24 miles).
Most of County Londonderry is on firmer ground than the clay belts of the south-east. Ground movement here is more often linked to soils, drains and trees than to mining. Across County Londonderry, most homes are Georgian and Victorian houses in Derry, brick terraces and post-war estates.
What happens during bowing wall repairs, step by step?
Decide restrain or rebuild
If the wall is badly out of plumb, has bricks crushing or follows removed internal walls, we recommend an engineer, and can arrange one. Their view sets whether restraint is enough or a section needs rebuilding.
Open up inside
Floorboards or a ceiling strip are lifted along the affected wall to expose the joists. We fit noggins where joists run alongside, and plan furniture moves with you, since this is the most disruptive part of the job.
Close up and make good
Boards are relaid, plaster and outside fixings made good, and cracked joints repointed. You receive a record of the restraint positions, which helps if you sell or if an engineer needs to check the wall again later.
What to look for before calling about bowing wall repairs
- Gutters or the roof edge no longer lining up with the wall
- Window frames pulling away from the brickwork at the sides
- A visible belly in the wall when you sight along it

How we usually approach bowing wall repairs
Restraint ties into the floor
Stainless restraint ties are drilled through the wall and fixed into the floor joists or into blocking between them. Where joists run parallel, noggins are fitted across several joists so the tie has something solid to hold. A neat plate or a buried fixing is left on the outside face.
Best for: Walls bowing at floor level where joists run alongside
Lateral restraint straps
Galvanised or stainless straps are fixed across three or more joists or rafters, turned down against the inside face of the wall and fixed into the masonry. They work well at ceiling and roof level, where the fixings stay hidden.
Best for: Gables and walls bowing near ceiling or roof level
Rules for bowing wall repairs in Northern Ireland
In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.
Questions about bowing wall repairs in Coleraine
How much should I budget for bowing wall repairs in Coleraine?
Guide prices for bowing wall repairs in Coleraine start from about £880 per wall, including VAT, on Northern Ireland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in County Londonderry crack?
County Londonderry has basalt, older hard rock and glacial deposits, with soft river ground along the Foyle and Bann. Only an investigation can say why a particular building has moved.
What is lateral restraint?
Lateral restraint is the connection that stops a wall moving sideways, provided by tying it to the floors and roof. Older houses often have little or none, especially where joists run parallel to the wall. Remedial ties and straps add that connection after the event.
Does a bowing wall need an engineer?
Often it does, especially if the bow is large, growing or linked to removed internal walls or chimney breasts. Small, long-standing bows can sometimes be restrained to a standard detail. Where the repair needs an engineer’s design or sign-off, we can arrange an independent chartered structural engineer.
