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
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.
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.
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.
Frequently asked questions
How much should I budget for bowing wall repairs in Andover?
Guide prices for bowing wall repairs in Andover start from about £1,100 per wall, including VAT, on South East 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 Andover?
We do. Andover and the surrounding area are covered, including nearby Winchester and Newbury. A free initial assessment from your photos is the first step.
Why do houses in Hampshire crack?
Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal movement near trees. 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.
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.
