Extension pulling away repairs in Galashiels
Rear and side extensions are common across Galashiels, 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.

Why does the ground in Scottish Borders matter for extension pulling away repairs?
We cover Galashiels and its postcode districts TD1, part of Scottish Borders, with a population of roughly 10,000. We also take enquiries from nearby Hawick (13 miles), Kelso (15 miles) and Peebles (15 miles).
Most of Scottish Borders 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 Scottish Borders, most homes are whinstone and sandstone mill-town houses, rural cottages and post-war estates.
What happens when we carry out extension pulling away repairs in Galashiels?
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.
Signs you may need extension pulling away repairs
- Daylight or draughts showing through the internal corner joint

- Patio doors or windows in the extension starting to bind

Which repair method suits a home in Galashiels?
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
Underpinning the extension
If the extension is still dropping because its footings are too shallow or on poor ground, they are taken deeper by mass concrete, beam-and-base or mini-piles. The engineer designs the scheme, and the junction is repaired once the new foundation is in.
Best for: Active movement from shallow footings, roots or soft ground
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.
Extension pulling away repairs in Galashiels: questions and answers
How much will extension pulling away repairs cost in Galashiels?
Guide prices for extension pulling away repairs in Galashiels 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 Galashiels?
Yes, Galashiels is covered, along with postcode districts TD1. We also cover nearby Hawick and Kelso.
Is the ground in Scottish Borders prone to subsidence?
The Borders are mostly older hard rock with glacial till and river gravels along the Tweed and its tributaries. Stone mill towns and rubble walls shape most structural repairs. Only an investigation can say why a particular building has moved.
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.
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.
