Retaining wall repairs in Chorley
On sloping plots in Chorley and across Lancashire, many retaining walls were built decades ago with little thought for drainage. As the soil stays wet and roots grow, those walls start to lean, and the lean usually speeds up rather than slows.

How we usually approach 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
What happens during retaining wall repairs, step by step?
Site assessment
On site we measure height and lean, check the drainage and the ground at the top and bottom, and look at access for digging out. Walls that support a drive, path or building, or retain more than a modest height, are referred to an engineer.
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.
What to look for before calling about retaining wall repairs
- Ground cracking or sinking along the top of the wall
- Wall leaning forward, or bulging out in the middle of its length
- No weep holes, or weep holes that never seem to drain
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.
Questions about retaining wall repairs in Chorley

Guide prices for retaining wall repairs in Chorley start from about £480 per wall, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Is the ground in Lancashire prone to subsidence?
Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns. Only an investigation can say why a particular building has moved.
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.
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.
