What should you know about the ground under Kelso?
Kelso (TD5) has around 7,000 residents and sits in Scottish Borders. If you are just outside Kelso, we also cover Galashiels (15 miles) and Hawick (18 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. What you mostly find across Scottish Borders: whinstone and sandstone mill-town houses, rural cottages and post-war estates.
Which repair method suits a home in Kelso?
Junction crack repair and tie-in
Where movement has stopped, the open joint between bay and house is raked out, stainless ties or helical bars are fixed across it, and the joint is repointed to match. Internal plaster along the crack is cut back and renewed before redecoration.
Best for: Old, stable cracks where the bay is no longer moving
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 Kelso?
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.
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.

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 Kelso: questions and answers
What is the price of bay window subsidence repairs in Kelso?
Guide prices for bay window subsidence repairs in Kelso 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 Kelso?
Yes, Kelso is covered, along with postcode districts TD5. We also cover nearby Galashiels and Hawick.
Does the ground around Kelso cause cracking?
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.
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.
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.
