Underpinning in Dundee
Before any underpinning goes ahead on a Dundee property, building control has to approve the design and inspect the excavations. Where the wall is shared, party wall notices may be needed too in England and Wales, so allow time for paperwork before the dig.

Shrinkable clay is less common in Angus and Dundee than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Angus and Dundee: sandstone tenements in Dundee, fishing-town houses and post-war estates.
Guide prices for underpinning in Dundee
Prices in Dundee are worked out on Scotland rates. They include VAT and are a starting point: access, the extent of the damage and whether an engineer or building control is involved all move the figure.
| Item | Guide price | Per |

| Mass-concrete underpinning | £950 – £1,400 | per metre of wall |
| Beam-and-base underpinning | £1,400 – £2,400 | per metre of wall |
| Mini-piled underpinning | £1,900 – £3,300 | per metre of wall |
| Engineer's design and building control feesest. | £760 – £2,400 | per scheme |
Methods for underpinning
Mass concrete underpinning
The traditional method. Short sections under the wall are dug out in a set sequence, usually about a metre at a time, and filled with concrete before the next section is opened. It suits moderate depths and good access, and it needs little specialist plant.
Best for: Shallow failures on firm ground found at moderate depth
Beam-and-base underpinning
A reinforced concrete beam is cast beneath or alongside the existing footing and carries the wall onto mass concrete bases at intervals. It spreads load well across variable ground and can mean less digging than continuous underpinning along the whole wall.
Best for: Longer runs of wall or heavier loads over variable ground
From first photo to finished repair
Engineer’s investigation
An independent chartered structural engineer studies the monitoring results, trial pits and soil tests, then decides whether underpinning is needed and which method suits. We can arrange the engineer if you do not already have one.
Design and approvals
The engineer produces drawings and calculations. We make the building control or building warrant application, and party wall notices are served where the law requires them, before any digging starts.
Fixed written price
With the design in hand we confirm a fixed price in writing, setting out the method, the length of wall, access arrangements and the making good. For insurance work we can price to the loss adjuster’s or engineer’s schedule.
Symptoms that point to underpinning
- Cracks that keep widening after the drains have been repaired
- Movement continuing through more than one winter of monitoring
- Footings found to be very shallow during a trial pit
Rules for underpinning 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
What is the price of underpinning in Dundee?
Guide prices for underpinning in Dundee start from about £950 per metre of 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 carry out underpinning in Dundee?
Yes, Dundee is covered, along with postcode districts DD1, DD2, DD3, DD4. We also cover nearby Carnoustie and Forfar.
Does the ground around Dundee cause cracking?
Angus and Dundee sit on Old Red Sandstone and igneous rock with glacial and raised-beach deposits. Hillside sites in Dundee mean retaining walls are common. Only an investigation can say why a particular building has moved.
Does my house really need underpinning?
Often not, because most subsidence is fixed by repairing drains or managing trees and then repairing the cracks. Underpinning is justified when monitoring shows movement continuing after the cause has been dealt with, or when the ground itself is unsuitable. An independent engineer should make that call.
Does underpinning need building control approval?
Yes, underpinning is building work and needs approval and inspections in England and Wales, a building warrant in Scotland, and council building control in Northern Ireland. Inspectors usually check the excavations before concrete is poured. We deal with building control as part of the job.
