Bay window subsidence repairs in Leicester
Repairing a subsiding bay in Leicester usually involves one of three routes: tie the junction, underpin with concrete, or install mini-piles. The engineer picks the route from the ground and the movement history, and we price it in writing.

What should you know about the ground under Leicester?
We cover Leicester and its postcode districts LE1, LE3, LE4, LE5, part of Leicestershire, with a population of roughly 370,000. We also take enquiries from nearby Wigston (4 miles), Mountsorrel (5 miles) and Earl Shilton (9 miles).
Leicestershire has a mix of ground, with clay in some places and firmer rock in others. Parts of Leicestershire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Leicestershire: Victorian terraces in Leicester and Loughborough, inter-war semis and large post-war estates.
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.
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.

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
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 Leicester?
Guide prices for bay window subsidence repairs in Leicester start from about £590 per bay, including VAT, on East Midlands 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 Leicester?
Yes, Leicester is covered, along with postcode districts LE1, LE3, LE4, LE5. We also cover nearby Wigston and Mountsorrel.
Does the ground around Leicester cause cracking?
Leicestershire has Mercia Mudstone, Lias clay and glacial till across much of the county, with the Coalville and Swadlincote coalfield in the north-west. Clay soils near large trees can move with the seasons. 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.
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.
