What is the ground like in Northumberland?
South-east Northumberland around Blyth, Ashington and Cramlington lies on the Northumberland coalfield, worked extensively in the past, under a cover of glacial clay. The north and west are hard rock and moorland.
Parts of Northumberland lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Northumberland: colliery terraces, stone farmhouses and villages, and post-war estates.
Methods for bowing wall repairs
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
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
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
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.
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.
Symptoms that point to bowing wall repairs
- Internal plaster cracks where a wall meets the ceiling
- Gaps opening between floorboards and the skirting on an outside wall
- Horizontal cracking at first-floor or ceiling level
- Gutters or the roof edge no longer lining up with the wall

Do you need approval 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
Why do houses in Northumberland crack?
South-east Northumberland around Blyth, Ashington and Cramlington lies on the Northumberland coalfield, worked extensively in the past, under a cover of glacial clay. The north and west are hard rock and moorland. Parts of Northumberland lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will bowing wall repairs cost in Northumberland?
On North East rates, bowing wall repairs starts from about £920 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
Do restraint ties show on the outside?
Some do and some do not. Certain ties leave a small round or square plate on the outside face, while others are fully recessed and pointed over. Straps fitted from inside leave no outside trace at all. We agree the finish with you before work starts.
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.
