Extension pulling away repairs in Scottish Borders
We carry out extension pulling away repairs across Scottish Borders, from the larger towns to smaller places nearby. Shrinkable clay is less common in Scottish Borders than in south-east England. Every job starts with the cause, then the repair is specified to match it.

What is the ground like in Scottish Borders?
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.
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 should you budget for extension pulling away repairs in Scottish Borders?
Prices in Scottish Borders 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 |
|---|---|---|
| Junction crack repair with stainless tiesest. | £570 – £1,900 | per junction |
| Movement joint and making goodest. | £380 – £1,150 | per junction |
| Underpinning the extension where needed | £950 – £2,400 | per metre of wall |
Repair options we may recommend
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
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
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 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.
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.
Is it time for extension pulling away repairs? Common signs
- Daylight or draughts showing through the internal corner joint
- Extension roof flashing lifting off the original wall
- A vertical crack or gap where the extension meets the house
- Patio doors or windows in the extension starting to bind
Do you need approval 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
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. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will extension pulling away repairs cost in Scottish Borders?
On Scotland rates, extension pulling away repairs starts from about £570 per junction, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
What is a movement joint?
A movement joint is a deliberate, flexible break in a wall that lets two parts of a building move slightly without cracking. It is filled with a compressible material and sealed. At an extension junction it can replace a rigid joint that keeps cracking.
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.
