From first photo to finished repair

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.
Fit the ties and straps
Ties are drilled through and fixed, or straps fitted and secured, at the spacing specified. Any rebuild is carried out at this stage, with temporary propping in place until the new brickwork has gained strength.
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.

Methods for bowing wall repairs

Partial rebuild

A section that has bowed beyond safe limits, or where bricks have crushed, is propped, taken down and rebuilt plumb with restraint built in. It is the most disruptive option, so it is kept to the area that genuinely needs it.

Best for: Badly distorted sections that cannot be tied back

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

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.

Frequently asked questions

How much should I budget for bowing wall repairs in Magherafelt?

Guide prices for bowing wall repairs in Magherafelt 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.

Can you survey a property in Magherafelt?

We do. Magherafelt and the surrounding area are covered, including nearby Cookstown and Ballymena. A free initial assessment from your photos is the first step.

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.

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.
