What should you know about the ground under Llanelli?
Postcode districts SA15 cover Llanelli, a Dyfed town of about 50,000 people. Nearby places we cover include Gorseinon (5 miles), Swansea (10 miles) and Ammanford (11 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. Across Dyfed, most homes are stone cottages, Victorian terraces in Llanelli and Carmarthen, and post-war estates.
What happens when we carry out subsidence repairs in Llanelli?
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.
Signs you may need subsidence repairs
- Doors and windows that start to stick or no longer close
- A gap opening between the skirting board and the floor
- Wallpaper rippling or tearing where the wall meets the ceiling

Which repair method suits a home in Llanelli?
Crack stitching and making good
Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.
Best for: Category 1 to 3 cracking in walls that are otherwise sound
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
Rules for 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.
Subsidence repairs in Llanelli: questions and answers
What is the price of subsidence repairs in Llanelli?
Guide prices for subsidence repairs in Llanelli 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 carry out subsidence repairs in Llanelli?
Yes, Llanelli is covered, along with postcode districts SA15. We also cover nearby Gorseinon and Swansea.
Does the ground around Llanelli 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.
How long should I wait before repairing subsidence cracks?
Usually until the cause has been dealt with and the engineer is satisfied that movement has stopped. On clay that can mean watching the house through a summer and a winter. Repairing too early risks the same cracks opening again.
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.
