Why does the ground in Dyfed matter for subsidence repairs?
Haverfordwest, Dyfed: about 15,000 residents across postcode districts SA61. Nearby places we cover include Milford Haven (7 miles).
Most of Dyfed is on firmer ground than the clay belts of the south-east. Parts of Dyfed lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Dyfed: Stone cottages, Victorian terraces in Llanelli and Carmarthen, and post-war estates.
How we usually approach subsidence repairs
Foundation strengthening
Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.
Best for: Ongoing movement where removing the cause has not worked
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
What happens during subsidence repairs, step by step?
Send photos or call
Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.
Find the cause
An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.
Deal with the cause
Drains are repaired, vegetation is managed on the engineer’s advice, or a foundation scheme is designed if nothing else will work. Where monitoring is recommended, readings run for several months to show the movement has stopped.
What to look for before calling about subsidence repairs

Rules for subsidence repairs in Wales
In Wales, the Welsh version of the Building Regulations applies.

Questions about subsidence repairs in Haverfordwest
How much will subsidence repairs cost in Haverfordwest?
Guide prices for subsidence repairs in Haverfordwest start from about £2,300 per property, 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 Haverfordwest?
Yes. We take enquiries from across Haverfordwest, including SA61, and from nearby places such as Milford Haven. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Dyfed prone to subsidence?
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.
Does subsidence always need underpinning?
No, most subsidence is repaired without underpinning. When a leaking drain is fixed or nearby vegetation is managed, the ground usually stabilises and the house needs only crack repairs. Foundation work is kept for movement that continues after the cause has gone.
Can I sell a house that has had subsidence?
Yes, though buyers and lenders will want paperwork. Keep the engineer’s report, monitoring results, the repair specification and any building control sign-off. A repaired house shown to be stable is far easier to sell than one with an open problem.
