What should you know about the ground under Tonbridge?
With roughly 36,000 people, Tonbridge spans postcode districts TN9, TN10, TN11 in Kent. If you are just outside Tonbridge, we also cover Tunbridge Wells (4 miles), Sevenoaks (6 miles) and Crowborough (10 miles).
Shrinkable clay is widespread in Kent. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.
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
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
From first photo to finished repair
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.
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.
Symptoms that point to 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
- Window frames pulling away from the brickwork at the sides

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 Tonbridge?
Guide prices for bowing wall repairs in Tonbridge 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 Tonbridge?
Yes. We take enquiries from across Tonbridge, including TN9, TN10, TN11, and from nearby places such as Tunbridge Wells and Sevenoaks. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Kent crack?
North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. Only an investigation can say why a particular building has moved.
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.
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.
