Clay shrinkage is less of a concern in Edinburgh and the Lothians, so other causes such as drains, poor footings or older walls are checked first. 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.

Which repair method suits a home in Edinburgh?
Traditional underpinning of the bay
The bay footing is excavated in short sections and new mass concrete is placed down to firmer ground below the zone affected by roots and seasons. Because a bay is a short length of wall, the work is compact, but it needs building control approval.
Best for: Active bay movement on firm ground at moderate depth
Mini-piled bay underpinning
Small piles are installed to depth around or beneath the bay and linked by a reinforced beam or needles that pick up its weight. It suits deeper soft ground and heavy root activity, and the compact rigs fit into a front garden.
Best for: Deep clay, nearby trees, or poor ground below the bay
What happens when we carry out bay window subsidence repairs in Edinburgh?
Photos and first view
Send photos of the outside junction, the inside corners and the window, with a scale. We give a free initial assessment and tell you whether the crack looks old and stable or whether an engineer should inspect first.
Engineer and checks
Where the cause is unclear, an independent chartered structural engineer inspects, sometimes with a trial pit at the bay and a drain survey. We can arrange the engineer. Monitoring may be suggested if the movement could be seasonal.
Carry out the work
Ties are fitted across the junction, or the bay is underpinned in sequence with building control inspecting the dig. The bay window and flashings are checked and eased or resealed where the movement has disturbed them.
Rules for bay window subsidence 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.
Bay window subsidence repairs in Edinburgh: questions and answers
What is the price of bay window subsidence repairs in Edinburgh?
Guide prices for bay window subsidence repairs in Edinburgh start from about £570 per bay, 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 bay window subsidence repairs in Edinburgh?
Yes, Edinburgh is covered, along with postcode districts EH1, EH2, EH3. We also cover nearby Musselburgh and Bonnyrigg.
Does the ground around Edinburgh 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.
Can I just fill the crack myself?
Filling it hides the evidence without dealing with the cause, and if the bay is still moving the crack will reopen. Photograph it with a scale and date first. If you plan to claim on insurance, tell your insurer before any repair, including filling.
Can a bay be underpinned without underpinning the house?
Yes, underpinning only the bay is common because it is usually the part on shallower footings. The engineer designs the junction so the strengthened bay and the existing house can move slightly without cracking, sometimes with a movement joint or ties.
