Bowing wall repairs in Trowbridge
In Trowbridge, as in most UK towns, bowing walls turn up mainly in older solid-walled terraces, where the floors were never properly tied to the front or side walls. Most can be held where they are with remedial restraint, without rebuilding.

What should you know about the ground under Trowbridge?
We cover Trowbridge and its postcode districts BA14, part of Wiltshire, with a population of roughly 41,000. We also take enquiries from nearby Westbury (4 miles), Melksham (5 miles) and Bath (8 miles).
Parts of Wiltshire have clay that can shrink near trees in dry spells. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Wiltshire: stone cottages, railway terraces in Swindon, and large post-war and new-build estates.
What to expect when we carry out bowing wall repairs
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.
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.

Repair options we may recommend
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
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
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.
Your bowing wall repairs questions

Is the ground in Wiltshire prone to subsidence?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. 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.
