Bay window subsidence repairs in Irvine
Front gardens across Irvine and Ayrshire often put hedges, trees and gullies close to the bay. Each can affect the ground under a shallow bay footing, so they are checked before deciding between a tie-in repair and underpinning.

Is Ayrshire prone to ground movement?
Postcode districts KA11, KA12 cover Irvine, a Ayrshire town of about 34,000 people. If you are just outside Irvine, we also cover Kilwinning (3 miles), Saltcoats (5 miles) and Troon (5 miles).
Shrinkable clay is less common in Ayrshire than in south-east England. Historic coal workings are recorded beneath parts of Ayrshire, and a coal mining search is worth checking where movement is unexplained. Typical buildings in Ayrshire: Sandstone villas and terraces in the coastal towns, miners' rows and post-war estates.

Repair options we may recommend
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
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
What to expect when we carry out bay window subsidence repairs
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.
Your bay window subsidence repairs questions
How much should I budget for bay window subsidence repairs in Irvine?
Guide prices for bay window subsidence repairs in Irvine 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.
Can you survey a property in Irvine?
Yes, Irvine is covered, along with postcode districts KA11, KA12. We also cover nearby Kilwinning and Saltcoats.
Why do houses in Ayrshire crack?
Ayrshire has a large coalfield, especially in the east around Kilmarnock and Cumnock, with recorded workings, and raised-beach sands and gravels along the coast. Only an investigation can say why a particular building has moved.
Is a crack between my bay and the house serious?
It is often not serious, especially if it is old, fine and unchanged for years. A crack that is widening, tapering or matched by sticking windows and a sloping bay floor needs looking at. An engineer’s inspection, sometimes with monitoring, will confirm whether the bay is still moving.
How long does bay underpinning take?
Traditional underpinning of a bay usually takes about a week on site, and mini-piling a little longer depending on depth. A junction tie-in without underpinning normally takes one to two days. Approvals and any monitoring beforehand add to the overall timeline.
