Extension pulling away repairs in Larkhall
Rear and side extensions are common across Larkhall, and so is the crack where new meets old. Usually it reflects the two parts sitting on different foundations, and the first question is whether the gap is still opening.

What should you know about the ground under Larkhall?
Larkhall, Lanarkshire: about 15,000 residents across postcode districts ML9. Nearby, we also cover Wishaw (3 miles), Hamilton (3 miles) and Motherwell (4 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. Housing stock in Lanarkshire: Miners' rows, sandstone tenements, inter-war council houses and new-town estates in East Kilbride and Cumbernauld.
Repair options we may recommend
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
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
What to expect when we carry out extension pulling away repairs
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.
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.

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.
Your extension pulling away repairs questions
How much will extension pulling away repairs cost in Larkhall?
Guide prices for extension pulling away repairs in Larkhall 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 Larkhall?
Yes. We take enquiries from across Larkhall, including ML9, and from nearby places such as Wishaw and Hamilton. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Lanarkshire prone to subsidence?
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.
Who is responsible if a recent extension is moving?
If the extension is recent, the original builder, the designer or building control records may be relevant, and you may have rights against the builder. Gather the plans, completion certificate and contract. Insurance often excludes defects in new construction, so check your policy.
Will my extension need underpinning?
Often not. Many separating extensions are fixed by repairing a drain, tying the junction or forming a movement joint. Underpinning is for extensions that keep dropping because their footings are too shallow or the ground beneath is poor, as shown by monitoring.
