Is Greater Manchester prone to ground movement?
Wigan (WN1, WN3, WN5) has around 180,000 residents and sits in Greater Manchester. Nearby places we cover include Hindley (2 miles), Ashton-in-Makerfield (4 miles) and Westhoughton (5 miles).
Greater Manchester has a mix of ground, with clay in some places and firmer rock in others. Parts of Greater Manchester lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Greater Manchester, most homes are red-brick terraces, mill-town stone terraces, inter-war semis and post-war estates.

Methods for subsidence repairs
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
Foundation strengthening
Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.
Best for: Ongoing movement where removing the cause has not worked
From first photo to finished repair
Send photos or call
Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.
Find the cause
An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.
Written quote
We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.
Symptoms that point to subsidence repairs
- A gap opening between the skirting board and the floor
- Wallpaper rippling or tearing where the wall meets the ceiling
- Diagonal cracks wider at the top, running from window or door corners
Rules for 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.
Frequently asked questions
How much will subsidence repairs cost in Wigan?
Guide prices for subsidence repairs in Wigan start from about £2,400 per property, 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 Wigan?
Yes. We take enquiries from across Wigan, including WN1, WN3, WN5, and from nearby places such as Hindley and Ashton-in-Makerfield. Send photos for a free initial view and we will tell you what happens next.
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.
Do you need to visit before giving a price?
Not at first. We give a free initial assessment from your photos or a call, and a no-obligation written quote once the scope is clear. A fixed price follows in writing once the repair is specified, which normally needs a survey.
Can I sell a house that has had subsidence?
Yes, though buyers and lenders will want paperwork. Keep the engineer’s report, monitoring results, the repair specification and any building control sign-off. A repaired house shown to be stable is far easier to sell than one with an open problem.
