From first photo to finished repair

  1. 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.

  2. 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.

  3. 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

  • Wall leaning forward, or bulging out in the middle of its length
  • No weep holes, or weep holes that never seem to drain
  • Horizontal or stepped cracks running along the face of the wall

Methods for retaining wall repairs

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

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

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 Bolton?

Guide prices for retaining wall repairs in Bolton 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.

Can you survey a property in Bolton?

Yes, Bolton is covered, along with postcode districts BL1, BL2, BL3. We also cover nearby Westhoughton and Radcliffe.

Why do houses in Greater Manchester crack?

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.

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.

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.
