Why does the ground in Cheshire matter for bay window subsidence repairs?
Postcode districts CW5 cover Nantwich, a Cheshire town of about 17,000 people. We also take enquiries from nearby Crewe (4 miles), Sandbach (8 miles) and Winsford (8 miles).
Cheshire has a mix of ground, with clay in some places and firmer rock in others. Historic brine and salt working has caused ground movement in parts of Cheshire in the past. Housing stock in Cheshire: Brick terraces in Crewe, Northwich and Warrington, Victorian villas in Chester, and inter-war and post-war semis.
How we usually approach 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
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
What happens during bay window subsidence repairs, step by step?
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.
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.
What to look for before calling about bay window subsidence repairs
- Bay roof or lead flashing pulling away from the main wall

- A vertical crack where the bay meets the front wall

Rules for bay window subsidence repairs in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Questions about bay window subsidence repairs in Nantwich
What is the price of bay window subsidence repairs in Nantwich?
Guide prices for bay window subsidence repairs in Nantwich start from about £575 per bay, including VAT, on North West 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 Nantwich?
We do. Nantwich and the surrounding area are covered, including nearby Crewe and Sandbach. A free initial assessment from your photos is the first step.
Does the ground around Nantwich cause cracking?
Most of Cheshire is glacial till over Mercia Mudstone. Around Northwich and the Weaver valley, historic salt and brine extraction has caused subsidence in the past, and a separate brine subsidence compensation scheme exists for parts of the county. 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 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.
