Subsidence repairs in Dunbartonshire
Homes in Dunbartonshire are mostly tenements. That matters for subsidence repairs: footings, wall construction and mortar all vary with the age of the building. Most of Dunbartonshire is on firmer ground than the clay belts of the south-east.

How do local ground conditions affect subsidence repairs in Dunbartonshire?
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.
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.

- Diagonal cracks wider at the top, running from window or door corners
- Wallpaper rippling or tearing where the wall meets the ceiling
- Fresh cracks showing on both the inside and outside of one wall

Which repair method suits a home in Dunbartonshire?
Crack stitching and making good
Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.
Best for: Category 1 to 3 cracking in walls that are otherwise sound
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
Foundation strengthening
Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.
Best for: Ongoing movement where removing the cause has not worked
What happens when we carry out subsidence repairs in Dunbartonshire?
Send photos or call
Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.
Written quote
We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.
Repairs and making good
Cracks are stitched and repointed outside, plaster is renewed along the crack lines inside, and sticking doors are eased. Where the work needs it, we deal with building control and hand over the paperwork.
Do you need approval for subsidence 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.

Subsidence repairs in Dunbartonshire: questions and answers
Does the ground around Bearsden cause cracking?
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. Parts of Dunbartonshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will subsidence repairs cost in Dunbartonshire?
On Scotland rates, subsidence repairs starts from about £2,400 per property, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Does subsidence always need underpinning?
No, most subsidence is repaired without underpinning. When a leaking drain is fixed or nearby vegetation is managed, the ground usually stabilises and the house needs only crack repairs. Foundation work is kept for movement that continues after the cause has gone.
How long should I wait before repairing subsidence cracks?
Usually until the cause has been dealt with and the engineer is satisfied that movement has stopped. On clay that can mean watching the house through a summer and a winter. Repairing too early risks the same cracks opening again.
How do I know if cracks are subsidence?
Subsidence cracks are usually tapered, run diagonally from door and window corners, and show on both faces of the wall. Fine vertical cracks in new plaster are more often shrinkage. An engineer’s inspection, sometimes with monitoring, is the reliable way to tell.
