Methods for retaining wall repairs

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

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

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.
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.

Rules for retaining wall repairs in Scotland

In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.

Frequently asked questions

How much should I budget for retaining wall repairs in Port Glasgow?

Guide prices for retaining wall repairs in Port Glasgow start from about £475 per wall, including VAT, on Scotland 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 Port Glasgow?

Yes. We take enquiries from across Port Glasgow, including PA14, PA15, and from nearby places such as Greenock and Alexandria. Send photos for a free initial view and we will tell you what happens next.

Why do houses in Renfrewshire and Inverclyde crack?

Renfrewshire has glacial till and Clyde alluvium with coal workings recorded in parts, while Inverclyde's towns climb steep slopes above the Clyde with many retaining walls. Only an investigation can say why a particular building has moved.

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.

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.
