How we usually approach 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

What happens during bowing wall repairs, step by step?

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.
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.

What to look for before calling about bowing wall repairs

Gutters or the roof edge no longer lining up with the wall

A visible belly in the wall when you sight along it

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.

Questions about bowing wall repairs in Cambridge

How much will bowing wall repairs cost in Cambridge?

Guide prices for bowing wall repairs in Cambridge start from about £1,050 per wall, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Cambridge?

Is the ground in Cambridgeshire prone to subsidence?

Gault Clay underlies much of the Cambridge area and Oxford Clay the west of the county around Peterborough and Huntingdon, while the northern fens are peat and silt that can shrink as they dry. Both clay and peat ground can move with the seasons. 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.

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.
