Retaining wall repairs in Alexandria
On sloping plots in Alexandria and across Dunbartonshire, 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.

Is Dunbartonshire prone to ground movement?
With roughly 25,000 people, Alexandria spans postcode districts G83 in Dunbartonshire. We also take enquiries from nearby Port Glasgow (5 miles), Helensburgh (6 miles) and Greenock (7 miles).
Shrinkable clay is less common in Dunbartonshire than in south-east England. Parts of Dunbartonshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Dunbartonshire: tenements, Victorian villas in Bearsden and Milngavie, and post-war estates.
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

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.
Symptoms that point to retaining wall repairs
- Ground cracking or sinking along the top of the wall
- Water seeping through joints, or white salt staining, after rain
- Horizontal or stepped cracks running along the face of the wall

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 will retaining wall repairs cost in Alexandria?
Guide prices for retaining wall repairs in Alexandria 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.
Do you cover Alexandria?
Yes, Alexandria is covered, along with postcode districts G83. We also cover nearby Port Glasgow and Helensburgh.
Is the ground in Dunbartonshire prone to subsidence?
Dunbartonshire has glacial till over sandstone and volcanic rock, with coal and ironstone workings recorded around Kirkintilloch and Bishopbriggs and soft river ground along the Clyde and Leven. Only an investigation can say why a particular building has moved.
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.
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.
