How do local ground conditions affect underpinning in Leigh?
Postcode districts WN7 cover Leigh, a Greater Manchester town of about 44,000 people. We also take enquiries from nearby Tyldesley (2 miles), Westhoughton (4 miles) and Hindley (4 miles).
Clay soils are found in parts of Greater Manchester. Parts of Greater Manchester lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Greater Manchester: Red-brick terraces, mill-town stone terraces, inter-war semis and post-war estates.
From first photo to finished repair
Design and approvals
The engineer produces drawings and calculations. We make the building control or building warrant application, and party wall notices are served where the law requires them, before any digging starts.
Excavation and concrete
Work runs in the sequence the engineer sets so the wall is never left unsupported over a long length. Building control inspects the excavations before concrete goes in, and each section is dry-packed tight to the footing above.
Crack repairs and handover
Once the new foundation has cured, cracks are stitched and repointed, inside walls are made good, and paths or patios disturbed by the dig are reinstated. You receive the building control completion paperwork for your records.
Symptoms that point to underpinning
- Cracks that keep widening after the drains have been repaired
- One corner of the house visibly lower than the others
- Footings found to be very shallow during a trial pit

Methods for underpinning
Mass concrete underpinning
The traditional method. Short sections under the wall are dug out in a set sequence, usually about a metre at a time, and filled with concrete before the next section is opened. It suits moderate depths and good access, and it needs little specialist plant.
Best for: Shallow failures on firm ground found at moderate depth
Beam-and-base underpinning
A reinforced concrete beam is cast beneath or alongside the existing footing and carries the wall onto mass concrete bases at intervals. It spreads load well across variable ground and can mean less digging than continuous underpinning along the whole wall.
Best for: Longer runs of wall or heavier loads over variable ground
Rules for underpinning 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.
Frequently asked questions
How much will underpinning cost in Leigh?
Guide prices for underpinning in Leigh start from about £960 per metre of wall, 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 cover Leigh?
Yes, Leigh is covered, along with postcode districts WN7. We also cover nearby Tyldesley and Westhoughton.
Is the ground in Greater Manchester prone to subsidence?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. Only an investigation can say why a particular building has moved.
Will underpinning affect selling my house?
It needs explaining to buyers, but a properly documented scheme is far better than unresolved movement. Keep the engineer’s design, the building control completion certificate and any insurance paperwork. Lenders and surveyors will usually ask for these before agreeing a sale.
Does my house really need underpinning?
Often not, because most subsidence is fixed by repairing drains or managing trees and then repairing the cracks. Underpinning is justified when monitoring shows movement continuing after the cause has been dealt with, or when the ground itself is unsuitable. An independent engineer should make that call.
