How we usually approach bowing wall repairs
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
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.
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.
Rules for bowing wall repairs in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Why do houses in Greater London crack?
Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. Only an investigation can say why a particular building has moved.
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.
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.
