Is Cheshire prone to ground movement?
We cover Congleton and its postcode districts CW12, part of Cheshire, with a population of roughly 26,000. Nearby places we cover include Biddulph (4 miles), Kidsgrove (5 miles) and Sandbach (6 miles).
Parts of Cheshire have clay that can shrink near trees in dry spells. Historic brine and salt working has caused ground movement in parts of Cheshire in the past. Typical buildings in Cheshire: Brick terraces in Crewe, Northwich and Warrington, Victorian villas in Chester, and inter-war and post-war semis.

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.
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 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.
Your bay window subsidence repairs questions
What is the price of bay window subsidence repairs in Congleton?
Guide prices for bay window subsidence repairs in Congleton 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 Congleton?
Yes. We take enquiries from across Congleton, including CW12, and from nearby places such as Biddulph and Kidsgrove. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Congleton 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.
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.
Does a bay window always need underpinning?
No, many bays are fixed by tying the junction and repointing, once any cause such as a leaking gully is put right. Underpinning is for bays still dropping after the cause has been dealt with, or with footings too shallow for the ground they sit on.
