Mining subsidence repairs in Lancashire

What is the ground like in Lancashire?

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.

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

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

Mining subsidence: settlement over old shallow mine workings. Indicative drawing, not to scale.

Do you need approval 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

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. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will mining subsidence repairs cost in Lancashire?

On North West rates, mining subsidence repairs starts from about £75 per metre of crack, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.
