Is Angus and Dundee prone to ground movement?
Carnoustie (DD7) has around 11,000 residents and sits in Angus and Dundee. Nearby, we also cover Arbroath (6 miles), Dundee (11 miles) and Forfar (12 miles).
Most of Angus and Dundee is on firmer ground than the clay belts of the south-east. Ground movement here is more often linked to soils, drains and trees than to mining. Across Angus and Dundee, most homes are sandstone tenements in Dundee, fishing-town houses and post-war estates.
Symptoms that point to extension pulling away repairs
- Daylight or draughts showing through the internal corner joint
- Floor level dropping where the extension and house floors meet
- Mastic or render at the joint repeatedly splitting open

Methods for extension pulling away repairs
Movement joint and making good
Where some seasonal movement is expected to continue, the junction is formed into a proper flexible movement joint with a compressible filler and sealant, so the two parts can move without cracking. Flashings and internal finishes are detailed to suit.
Best for: Minor ongoing movement that does not threaten the structure
Junction crack repair with stainless ties
The open joint is cut out, stainless ties or helical bars are fixed across it into both the old and new masonry, and the joint is repointed or rendered to match. Inside, the corner is replastered. This suits extensions that moved once and have since stopped.
Best for: Settled extensions with a stable gap at the junction
From first photo to finished repair
Show us the junction
Send photos of the crack outside, the internal corner and any flashing above, with a measure for scale. We give a free initial assessment and an initial view on whether the gap is likely old or still opening.
Repair the junction
Drains are repaired first if they are leaking. The joint is then tied, formed as a movement joint or rebuilt after underpinning, with roof flashings reset so the junction stays watertight. Building control is handled where needed.
Finish and hand over
Internal corners are replastered, skirtings and coving refixed, and doors or windows in the extension eased where the movement affected them. Records of the repair and any approvals are passed to you.
Rules for extension pulling away 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 extension pulling away repairs cost in Carnoustie?
Guide prices for extension pulling away repairs in Carnoustie start from about £570 per junction, 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 Carnoustie?
We do. Carnoustie and the surrounding area are covered, including nearby Arbroath and Dundee. A free initial assessment from your photos is the first step.
Is the ground in Angus and Dundee prone to subsidence?
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.
Can I just fill the gap with mastic?
Mastic can keep water out short term, but it does not stop movement or reconnect the walls. If the gap reopens after filling, something is still moving. Photograph and measure it over a few months first, so an engineer can see the trend.
Is it normal for an extension to crack at the join?
A fine crack at the junction is fairly common, especially in the first few years as a new extension settles. It becomes a concern when the gap is widening, tapering, letting in water or matched by sticking doors and sloping floors. Those signs point to continuing movement.
