Mining subsidence repairs in Blackburn
Whether old mine workings lie beneath Blackburn 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.

What is the ground like in Lancashire?
Blackburn, Lancashire: about 150,000 residents across postcode districts BB1, BB2. If you are just outside Blackburn, we also cover Darwen (4 miles), Accrington (5 miles) and Chorley (9 miles).
Clay soils are found in parts of Lancashire. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Lancashire: stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.
What to expect when we carry out mining subsidence repairs
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.
Repairs and records
Work proceeds once any ground treatment is complete and the engineer is satisfied. We stitch, stabilise or underpin as specified, make good inside and out, deal with building control where needed, and hand over records for your file.

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
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
How much will mining subsidence repairs cost in Blackburn?
Guide prices for mining subsidence repairs in Blackburn 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 Blackburn?
Yes, Blackburn is covered, along with postcode districts BB1, BB2. We also cover nearby Darwen and Accrington.
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.
Can mining subsidence start again years later?
It can, particularly over shallow workings or old shafts, where collapse can happen long after mining ended. Movement from deep longwall mining generally settled within a few years of extraction. An engineer can judge whether current damage is old, settled cracking or new movement.
What should I do if a hole opens in my garden?
Keep everyone away from it and do not try to fill it yourself. Report it straight away to the Mining Remediation Authority if coal mining may be involved, or to your council and insurer otherwise. Old shafts can be deeper and wider than the visible hole suggests.
