Methods for bowing wall repairs
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
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.
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.
Rules for bowing wall repairs in Wales
In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.
Frequently asked questions
How much will bowing wall repairs cost in Barry?
Guide prices for bowing wall repairs in Barry start from about £920 per wall, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Barry?
Yes, Barry is covered, along with postcode districts CF62, CF63. We also cover nearby Penarth and Cardiff.
Is the ground in South Glamorgan prone to subsidence?
Cardiff is built on Mercia Mudstone, river gravels and alluvium, and the Vale of Glamorgan on Lias limestone and clay. Soft alluvium near the rivers and docks can settle. 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.
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.
