Mining subsidence repairs in Chorley
Whether old mine workings lie beneath Chorley is a question for the mining records, not for guesswork. A coal mining report shows recorded seams, shafts and past workings nearby, while an engineer’s inspection is what links any damage to them.

How do local ground conditions affect mining subsidence repairs in Chorley?
Chorley, Lancashire: about 34,000 residents across postcode districts PR6, PR7. Nearby places we cover include Horwich (4 miles), Leyland (4 miles) and Darwen (7 miles).
Lancashire has a mix of ground, with clay in some places and firmer rock in others. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Lancashire: Stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.
What happens when we carry out mining subsidence repairs in Chorley?
Report and photograph
Photograph every crack with a scale and note the date it appeared. Report suspected coal-mining damage to the Mining Remediation Authority, or the operator of a working mine, and notify your home insurer. Time limits can apply, so report promptly.
Check the mining record
A coal mining report or a search of mining records shows whether recorded workings or shafts lie near the property. Records are incomplete, so a clear report does not rule mining out, and a recorded seam nearby does not prove it is the cause.
Written price to the scope
We price the repair from the engineer’s or claim schedule and confirm a fixed price in writing once the work is specified. Where a claim body or insurer is handling the repair, their own process for appointing contractors applies.

Which repair method suits a home in Chorley?
Crack stitching and making good
Where the ground has stopped moving and the damage is cracking, the walls are stitched with stainless helical bars, repointed and replastered. This covers a large share of mining damage, especially legacy movement that settled years ago and left cracks behind.
Best for: Cracking after movement that has now stopped
Underpinning to sound ground
Where the engineer specifies it, foundations are taken down by mass concrete, beam-and-base or mini-piles to ground that will not move further. On mining sites the design often follows grouting of old workings so the new foundation sits above a stable mass.
Best for: Ongoing movement or damage beyond what crack repairs can hold
Rules for mining 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.
Mining subsidence repairs in Chorley: questions and answers
How much will mining subsidence repairs cost in Chorley?
Guide prices for mining subsidence repairs in Chorley start from about £75 per metre of crack, 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 Chorley?
Yes. We take enquiries from across Chorley, including PR6, PR7, and from nearby places such as Horwich and Leyland. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Lancashire prone to subsidence?
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.
Who pays for coal-mining subsidence damage?
Liability for damage from past coal mining usually rests with the Mining Remediation Authority, or with the operator of a working mine. They investigate whether coal mining caused the damage before agreeing any repair. Tell your home insurer as well, because policy cover and the mining claim can overlap.
Can you repair mining damage that is not part of a claim?
Yes. If the damage is old and settled, or a claim has been closed, we can repair it privately. Send photos for a free initial assessment and you will receive a no-obligation written quote. If the cause is unclear, an engineer’s inspection first is sensible.
