From first photo to finished repair
Engineer’s design
Where the wall needs it, an independent chartered structural engineer is appointed to design the repair or new wall, including footing, thickness, reinforcement and drainage. We can arrange this, and the design forms the basis of the quote.
Written quote
You receive a no-obligation written quote covering demolition, excavation, temporary support, the footing, the new or repaired wall, drainage and spoil removal. It becomes a fixed price in writing once the repair is specified.
Build and drain
The failing section is taken down, the soil supported in short lengths, and the footing cast. The wall is rebuilt with drainage behind it, backfilled with free-draining material, and building control inspects where the work needs it.
Symptoms that point to retaining wall repairs
- Bricks or blocks pushed out of line, or coping stones sliding off
- Water seeping through joints, or white salt staining, after rain
- Horizontal or stepped cracks running along the face of the wall

Methods for retaining wall repairs
Drainage and minor repairs
Blocked weep holes are cleared or new ones drilled, and where practical a drainage layer is formed behind the wall with an outlet at its base. Loose copings are rebedded, open joints repointed and a few damaged bricks replaced. For a low wall that has not moved much, this can be enough.
Best for: Low walls that are damp or slightly weathered but still upright
Temporary support and reducing load
While a repair is designed and programmed, a dangerous wall may be propped, or soil and loads near the top removed to reduce the push. Moving parked cars or a shed back from the wall is sometimes the simplest first step.
Best for: Walls that are moving now and need making safe
Rules for retaining 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 retaining wall repairs in Northampton?
Guide prices for retaining wall repairs in Northampton start from about £490 per wall, including VAT, on East Midlands 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 Northampton?
We do. Northampton and the surrounding area are covered, including nearby Wellingborough and Daventry. A free initial assessment from your photos is the first step.
Why do houses in Northamptonshire crack?
Northamptonshire sits largely on Lias clay and Jurassic ironstones and limestones, with historic ironstone quarrying around Corby and Kettering. The clay vales are prone to shrinkage near trees. Only an investigation can say why a particular building has moved.
Who is responsible for a retaining wall between two properties?
Usually the owner of the higher ground, because the wall holds up their land, but it depends on your title deeds and how the wall came to be built. Check the deeds first, take advice if it is unclear, and agree the repair with your neighbour before work starts.
Is a leaning retaining wall dangerous?
It can be, especially if the lean is getting worse, the wall is tall, or there is a path, drive or building next to it. A wall that has leaned slightly for decades may be stable, but one that has moved recently should be kept clear and assessed soon.
