What happens when we carry out bowing wall repairs in Derry?
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.
Signs you may need bowing wall repairs
- Horizontal cracking at first-floor or ceiling level
- Internal plaster cracks where a wall meets the ceiling
- A visible belly in the wall when you sight along it

Which repair method suits a home in Derry?
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
Stitching a delaminating wall
Where the layers of a solid wall have separated, long stainless ties are drilled in from the face and bonded into the inner layer to bind the wall together again. This is often combined with restraint ties, so the wall is both reconnected through its thickness and tied back to the structure.
Best for: Solid walls where the outer layer has pulled away

Bowing wall repairs in Derry: questions and answers
What is the price of bowing wall repairs in Derry?
Guide prices for bowing wall repairs in Derry 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.
Do you carry out bowing wall repairs in Derry?
We do. Derry and the surrounding area are covered, including nearby Strabane and Limavady. A free initial assessment from your photos is the first step.
Does the ground around Derry cause cracking?
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.
How do I know if my wall is bowing?
Hold a long spirit level or a taut string against the wall and look for a gap in the middle. From inside, gaps between floorboards and skirting on an outside wall are a common clue. Photos showing the gap help us judge it before a visit.
Is a bowing wall dangerous?
A bowing wall is not always dangerous, but it should never be ignored. Many have been slightly out of line for decades. A bow that is growing, crushing bricks or appeared after building work is more serious, and an engineer should look at it promptly. Your engineer will confirm.
