Is Northumberland prone to ground movement?
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. Across Northumberland, most homes are colliery terraces, stone farmhouses and villages, and post-war estates.
Methods for retaining wall repairs
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
Structural repair and partial rebuild
A leaning or bulging section is taken down, the soil behind dug out and supported, and the wall rebuilt on a new footing with drainage and, where specified, reinforcement tied into the sound wall either side. The engineer’s design sets footing size and wall thickness.
Best for: A section that has moved while the rest stays sound
Rebuilding on new footings
Where the whole wall is failing, it is replaced with a new retaining wall on a properly sized footing, with free-draining backfill, a membrane, weep holes and a drain at the base. Reinforced blockwork faced in brick or stone is common, so the wall matches its surroundings.
Best for: Walls failing along their length, or retaining significant height

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
- Ground cracking or sinking along the top of the wall
- Bricks or blocks pushed out of line, or coping stones sliding off
- Horizontal or stepped cracks running along the face of the wall
- No weep holes, or weep holes that never seem to drain

Do you need approval 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
Is the ground in Northumberland prone to subsidence?
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 retaining wall repairs cost in Northumberland?
On North East rates, retaining wall repairs starts from about £460 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Does home insurance cover a collapsed garden retaining wall?
Often not, because many policies exclude garden walls unless the house is damaged by the same event, and gradual failure is usually excluded. A collapse caused by landslip or a sudden escape of water may be treated differently. Check your schedule and tell your insurer before permanent repairs start.
How long does a retaining wall rebuild take?
Drainage and minor repairs usually take a day or two. Rebuilding a garden retaining wall on new footings typically takes one to three weeks, depending on its length, height, access for digging and any wait for the engineer’s design or inspections.
Do I need an engineer for a retaining wall?
For low walls holding back a planting bed, often not. Walls retaining more than a modest height, often taken as more than about a metre, or supporting a drive, path, building or neighbour’s land, generally need an engineer’s design. An independent chartered structural engineer is appointed where needed, and we can arrange this.
