Extension pulling away repairs in Blantyre
An extension pulling away from a Blantyre house is often a drain problem, a shallow footing or a missing tie-in, rather than a failing building. Finding out which applies decides whether the fix is a junction repair or new foundations.

What is the ground like in Lanarkshire?
Postcode districts G71, G72, ML3 cover Blantyre, a Lanarkshire town of about 17,000 people. We also take enquiries from nearby Cambuslang (3 miles), Hamilton (3 miles) and Bellshill (3 miles).
Most of Lanarkshire is on firmer ground than the clay belts of the south-east. Historic coal workings are recorded beneath parts of Lanarkshire, and a coal mining search is worth checking where movement is unexplained. What you mostly find across Lanarkshire: miners' rows, sandstone tenements, inter-war council houses and new-town estates in East Kilbride and Cumbernauld.
How we usually approach 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
What happens during extension pulling away repairs, step by step?
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.
Find what is moving
An independent chartered structural engineer can inspect, and we can arrange one. A drain survey under the extension, a trial pit at its footing and tell-tale monitoring across the joint are common checks before choosing the repair.
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.
What to look for before calling about extension pulling away repairs
- Extension roof flashing lifting off the original wall
- Daylight or draughts showing through the internal corner joint
- A vertical crack or gap where the extension meets the house

There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Questions about extension pulling away repairs in Blantyre
What is the price of extension pulling away repairs in Blantyre?
Guide prices for extension pulling away repairs in Blantyre 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 carry out extension pulling away repairs in Blantyre?
We do. Blantyre and the surrounding area are covered, including nearby Cambuslang and Hamilton. A free initial assessment from your photos is the first step.
Does the ground around Blantyre cause cracking?
Lanarkshire lies on the Central Coalfield, mined intensively in the past around Hamilton, Motherwell, Airdrie and Coatbridge, so recorded workings are common beneath towns. Only an investigation can say why a particular building has moved.
Why is my extension pulling away from my house?
Usually because the extension and the house sit on different foundations that react differently to the ground. Shallow extension footings, leaking drains under the extension, nearby roots and weak tie-ins between old and new walls are the common causes.
Can a drain under my extension cause it to move?
Yes, a cracked or displaced drain beneath or beside an extension can soften clay or wash away fine soil. A CCTV drain survey usually finds it. Repairing the drain is often the first and most important step before any repair to the walls.
