Which repair method suits a home in West Glamorgan?
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
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
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
What happens when we carry out bowing wall repairs in West Glamorgan?
Assess the bow
We look at where the wall bows, how far it is out of plumb and how the floors and roof meet it. Photographs from your phone held flat against the wall often show the shape clearly before anyone visits.
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.

Bowing wall repairs in West Glamorgan: questions and answers
Does the ground around Swansea cause cracking?
Swansea and Neath Port Talbot lie on the South Wales coalfield, with historic workings, tips and steep valley sides, and softer estuarine ground around the docks. Historic coal workings are recorded beneath parts of West Glamorgan, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.
How much will bowing wall repairs cost in West Glamorgan?
On Wales rates, bowing wall repairs starts from about £920 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
Can a bowing wall be pushed back straight?
Usually not. Masonry rarely returns to plumb without cracking, so the normal aim is to stop further movement and leave the wall where it is. If the bow is too great to accept, that section is rebuilt rather than forced back.
Will I need to move out during bowing wall repairs?
Usually not. Restraint work means lifting some floorboards or a strip of ceiling along one wall, so a room or two is disrupted for a few days. A partial rebuild of an external wall can be more involved, and we will talk it through with you first.
