Mining subsidence repairs in Milford Haven
Cracking in a Milford Haven home is more often caused by clay, trees or drains than by mining, even in areas with a mining past. If mining is a possibility, report it to the right body early and keep a dated photo record of every crack.

What should you know about the ground under Milford Haven?
Milford Haven (SA73) has around 14,000 residents and sits in Dyfed. Neighbouring towns we cover: Haverfordwest (7 miles).
Clay shrinkage is less of a concern in Dyfed, so other causes such as drains, poor footings or older walls are checked first. Parts of Dyfed lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Dyfed: stone cottages, Victorian terraces in Llanelli and Carmarthen, and post-war estates.

Methods for mining subsidence repairs
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
From first photo to finished repair
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.
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.
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.
Frequently asked questions
What is the price of mining subsidence repairs in Milford Haven?
Guide prices for mining subsidence repairs in Milford Haven 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 carry out mining subsidence repairs in Milford Haven?
Yes. We take enquiries from across Milford Haven, including SA73, and from nearby places such as Haverfordwest. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Milford Haven cause cracking?
The western edge of the South Wales coalfield lies beneath Llanelli, Ammanford and parts of Pembrokeshire, while the rest of the area is older hard rock with glacial deposits in the valleys. Only an investigation can say why a particular building has moved.
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.
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.
