Typical buildings in Merseyside: Victorian terraces and villas, inter-war council estates and post-war semis.

Repair options we may recommend
Pricing an engineer’s repair scope
When a claim is under way, the engineer or claim handler usually writes the scope of repairs. We price that schedule item by item, at no charge to request, and carry out the work if you choose us. Anything outside the scope is shown separately.
Best for: Homeowners with a mining claim or engineer’s report in hand
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
What to expect when we carry out mining subsidence repairs
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.
Engineer’s assessment
An independent chartered structural engineer inspects the damage and, if needed, recommends drilling or ground investigation to locate voids. We can arrange the engineer. Their report sets out the cause, whether movement has stopped and what repair is needed.
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.

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.
Your mining subsidence repairs questions
What is the price of mining subsidence repairs in St Helens?
Guide prices for mining subsidence repairs in St Helens 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 carry out mining subsidence repairs in St Helens?
Yes. We take enquiries from across St Helens, including WA9, WA10, WA11, and from nearby places such as Prescot and Ashton-in-Makerfield. Send photos for a free initial view and we will tell you what happens next.
Does the ground around St Helens cause cracking?
Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. Only an investigation can say why a particular building has moved.
How do I make a mining subsidence claim?
Start by reporting the damage to the Mining Remediation Authority, describing when it appeared and including photographs. They will usually arrange an inspection and investigation. Report promptly, because time limits can apply. Keep copies of everything you send, and notify your home insurer in parallel.
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.
