Extension pulling away repairs in Bonnyrigg
An extension pulling away from a Bonnyrigg 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 Edinburgh and the Lothians?
Postcode districts EH18, EH19, EH24 cover Bonnyrigg, a Edinburgh and the Lothians town of about 18,000 people. Neighbouring towns we cover: Mayfield (3 miles), Musselburgh (5 miles) and Penicuik (6 miles).
Most of Edinburgh and the Lothians is on firmer ground than the clay belts of the south-east. Parts of Edinburgh and the Lothians lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Edinburgh and the Lothians, most homes are sandstone tenements and Georgian terraces, miners' rows, bungalows and post-war estates.
From first photo to finished repair
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.
Choose the fix
The engineer decides between ties, a movement joint or underpinning. We confirm a fixed price in writing once the repair is specified, covering the junction, flashings, internal finishes and any foundation work.
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.
Symptoms that point to extension pulling away repairs
- A vertical crack or gap where the extension meets the house
- Mastic or render at the joint repeatedly splitting open
- Extension roof flashing lifting off the original wall

Methods for extension pulling away repairs
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
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
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
What is the price of extension pulling away repairs in Bonnyrigg?
Guide prices for extension pulling away repairs in Bonnyrigg 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 Bonnyrigg?
Yes. We take enquiries from across Bonnyrigg, including EH18, EH19, EH24, and from nearby places such as Mayfield and Musselburgh. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Bonnyrigg cause cracking?
Edinburgh is volcanic and sedimentary rock with glacial till, while the Midlothian and East Lothian coalfields and oil-shale workings in West Lothian have left recorded mine workings and bings. Only an investigation can say why a particular building has moved.
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.
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.
