Retaining wall repairs in Wigan
A garden retaining wall in Wigan holds back far more weight than it looks, and the push increases every time the soil behind it gets wet. Most leaning or bulging walls turn out to have poor drainage, thin construction or shallow footings, often all three.

What is the ground like in Greater Manchester?
Postcode districts WN1, WN3, WN5 cover Wigan, a Greater Manchester town of about 180,000 people. Nearby places we cover include Hindley (2 miles), Ashton-in-Makerfield (4 miles) and Westhoughton (5 miles).
Greater Manchester has a mix of ground, with clay in some places and firmer rock in others. Parts of Greater Manchester lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Greater Manchester, most homes are red-brick terraces, mill-town stone terraces, inter-war semis and post-war estates.
What happens when we carry out retaining wall repairs in Wigan?
Photos and measurements
Send photos of the whole wall from the front and the end, so any lean shows, plus close-ups of cracks and weep holes. Tell us roughly how tall it is and what sits at the top, such as lawn, patio, drive or a building.
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.
Signs you may need retaining wall repairs
- Horizontal or stepped cracks running along the face of the wall
- No weep holes, or weep holes that never seem to drain
- Bricks or blocks pushed out of line, or coping stones sliding off

Which repair method suits a home in Wigan?
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.
Retaining wall repairs in Wigan: questions and answers

Do you cover Wigan?
We do. Wigan and the surrounding area are covered, including nearby Hindley and Ashton-in-Makerfield. A free initial assessment from your photos is the first step.
Is the ground in Greater Manchester prone to subsidence?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. Only an investigation can say why a particular building has moved.
Can a bulging retaining wall be saved?
Sometimes, if the bulge is small, the wall is low and the cause is mainly poor drainage. Improving drainage and repairing the face may stop further movement. A wall that has bulged a lot, cracked through or moved at its base usually needs that section rebuilding on a proper footing.
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.
