What is the ground like in Dyfed?
We cover Llanelli and its postcode districts SA15, part of Dyfed, with a population of roughly 50,000. Nearby places we cover include Gorseinon (5 miles), Swansea (10 miles) and Ammanford (11 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.
What happens when we carry out structural surveys and crack monitoring in Llanelli?
Free initial assessment
Send photos of the cracks with something for scale and tell us when they appeared. We give a free view on whether an engineer’s inspection is worthwhile, and whether your insurer should be told first.
Seasonal readings
Readings are taken at intervals across the seasons, typically including late summer when clay is driest and late winter when it is wettest. The engineer checks each set against the base reading and decides whether more visits are needed.
Repair or close
If the readings show the house is stable, the engineer specifies the repair and we confirm a fixed price in writing. If movement continues, the cause is investigated further before a foundation repair is designed.

Which repair method suits a home in Llanelli?
Engineer’s structural inspection and report
A chartered structural engineer visits, records the cracks, checks the walls, floors, drains and nearby trees, and writes a report on the likely cause and next steps. It may recommend monitoring, investigations such as trial pits, or a repair specification.
Best for: A first expert opinion on any significant cracking
Level monitoring
Survey points are fixed around the building and their heights measured against a stable datum on each visit. This shows whether one part of the house is dropping or rising compared with the rest, which crack widths alone cannot reveal.
Best for: Suspected subsidence or heave across a whole house
Rules for structural surveys and crack monitoring in Wales
In Wales, small like-for-like repairs do not usually need approval, but work that alters or strengthens the structure needs building control under the Welsh Building Regulations, and the Party Wall etc. Act 1996 can apply to shared walls.
Structural surveys and crack monitoring in Llanelli: questions and answers
What is the price of structural surveys and crack monitoring in Llanelli?
Guide prices for structural surveys and crack monitoring in Llanelli start from about £460 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 structural surveys and crack monitoring 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.
What is a tell-tale on a crack?
A tell-tale is a small gauge fixed across a crack, with two overlapping plates marked in millimetres. As the crack opens, closes or shears, the plates move against each other and the reading changes. It gives a simple, repeatable record that anyone can check between visits.
When should I get a structural engineer’s report?
It is worth getting one when cracks are wider than a few millimetres, tapered, getting worse, or accompanied by sticking doors and sloping floors. A mortgage valuer or insurer asking for one is another clear trigger. Fine, stable hairline cracks often do not need one.
