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

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
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
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.
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.
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.

Rules for mining subsidence repairs in Wales
In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.
Your mining subsidence repairs questions
How much will mining subsidence repairs cost in Rhondda?
Guide prices for mining subsidence repairs in Rhondda start from about £75 per metre of crack, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Rhondda?
Yes. We take enquiries from across Rhondda, including CF40, CF41, CF43, and from nearby places such as Tonypandy and Mountain Ash. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Mid Glamorgan prone to subsidence?
Mid Glamorgan lies on the South Wales coalfield, with dense historic workings, spoil tips and steep valley sides. Landslip, retaining walls and mining legacy are all live issues in the valleys. Only an investigation can say why a particular building has moved.
What about salt, lead or ironstone mining?
Damage from non-coal mining follows different routes. Cheshire’s brine areas have their own statutory compensation arrangements, while metal, ironstone and limestone workings often have no equivalent scheme, leaving your home insurer as the main route. A solicitor or your insurer can confirm which applies.
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.
