What should you know about the ground under Bonnyrigg?
We cover Bonnyrigg and its postcode districts EH18, EH19, EH24, part of Edinburgh and the Lothians, with a population of roughly 18,000. Nearby, we also cover Mayfield (3 miles), Musselburgh (5 miles) and Penicuik (6 miles).
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. What you mostly find across Edinburgh and the Lothians: sandstone tenements and Georgian terraces, miners' rows, bungalows and post-war estates.

Methods for bay window subsidence repairs
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
From first photo to finished repair
Agree the repair
The engineer decides between tie-in repairs and underpinning. We confirm a fixed price in writing once the repair is specified, including scaffolding if needed, the bay window, roof flashing and internal making good.
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.
Make good inside
Plaster around the bay and along the junction is renewed, the window board is refixed and the room is ready for decoration. Building control paperwork, where it applies, is passed to you for your records.
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.
Frequently asked questions
What is the price of bay window subsidence repairs in Bonnyrigg?
Guide prices for bay window subsidence repairs in Bonnyrigg 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 Bonnyrigg?
We do. Bonnyrigg and the surrounding area are covered, including nearby Mayfield and Musselburgh. A free initial assessment from your photos is the first step.
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.
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.
Will the bay window need replacing?
Usually not. Most windows can be eased, packed or resealed once the bay is stable. If the frame has twisted badly or the glass has cracked, replacement may be worth considering. Under a claim, upgrades beyond like-for-like are normally priced separately.
