Underpinning in Skelmersdale
Most underpinning in Skelmersdale, as elsewhere, is partial, strengthening one corner or a single wall rather than the whole house. The engineer plans how the new foundation meets the old so that the junction does not become the next place to crack.

What is the ground like in Lancashire?
We cover Skelmersdale and its postcode districts WN8, part of Lancashire, with a population of roughly 39,000. Nearby, we also cover Ormskirk (5 miles), Wigan (6 miles) and Kirkby (7 miles).
Parts of Lancashire have clay that can shrink near trees in dry spells. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Lancashire, most homes are stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.
Symptoms that point to underpinning
- One corner of the house visibly lower than the others
- Floors sloping noticeably towards one external wall
- Movement continuing through more than one winter of monitoring

Methods for underpinning
Mini-piled underpinning
Small-diameter piles are driven or bored down to firm ground and linked by a reinforced beam or needles that pick up the wall. Compact rigs fit through narrow access, and the method reaches depths that would be impractical to excavate by hand.
Best for: Deep soft ground, tree roots, or restricted access
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

Engineer’s investigation
An independent chartered structural engineer studies the monitoring results, trial pits and soil tests, then decides whether underpinning is needed and which method suits. We can arrange the engineer if you do not already have one.
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.
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 should I budget for underpinning in Skelmersdale?
Guide prices for underpinning in Skelmersdale 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.
Can you survey a property in Skelmersdale?
Yes, Skelmersdale is covered, along with postcode districts WN8. We also cover nearby Ormskirk and Wigan.
Why do houses in Lancashire crack?
Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns. Only an investigation can say why a particular building has moved.
Do I need to tell my neighbours about underpinning?
In England and Wales you usually do. Underpinning a party wall normally needs two months’ notice, and excavating near a neighbour’s foundations needs one month’s notice under the Party Wall etc. Act 1996. Scotland and Northern Ireland have no equivalent Act, but agreeing the work in writing still helps.
Which underpinning method is best?
The right method depends on how deep firm ground lies, the load on the wall and the access. Mass concrete suits moderate depths, beam-and-base spreads heavier loads, and mini-piles reach deep soft ground or work through tight access. The engineer chooses the method from the site investigation.
