Cwmbran was designed on a drawing board, and many of its ground floors were poured with the pipework already inside. When those pipes fail, we locate the exact point — no floors broken out on a hunch.
New town construction gives Cwmbran a leak profile unlike anywhere else in South Wales: thousands of homes of similar age, similar build and similar plumbing, now reaching the stage of life where embedded pipework starts to fail. We give NP44 households and landlords a precise answer before the repair conversation even starts.
Our engineers cover the distance from Neath in a little over an hour, and the town sits comfortably inside our fixed-fee area — £480 + VAT for the full survey, quoted once and never revised upwards. Tracer gas, thermal imaging, acoustic detection, borescope access and moisture metering are all part of that single figure.
Because so many Cwmbran leaks end up as escape-of-water claims, we finish each survey with documentation an insurer can act on immediately: the confirmed position, thermal and moisture evidence, and photographs keyed to a floor plan of the affected rooms.
Local knowledge
Designated a new town in 1949, Cwmbran went up at pace through the 1950s, 60s and 70s across planned neighbourhoods such as Fairwater, Greenmeadow, St Dials, Coed Eva and Thornhill. The construction habits of that era — solid slab ground floors, copper heating circuits laid straight into the screed, and a share of system-built housing — leave many homes relying on sixty-year-old pipework cast into the structure itself.
Happily, that is the scenario our instruments handle best: a pinhole beneath a lounge floor registers as a warm anomaly on the thermal camera and a gas reading at the surface, with nothing lifted until the position is confirmed. The pre-new-town cores at Old Cwmbran and Pontnewydd add a second category — suspended floors and much-altered Victorian pipe runs — while Croesyceiliog and Llanyravon mix eras, and the modern pockets around Henllys bring push-fit plastic systems with their own failure points.
WHAT WE FIND IN CWMBRAN
Coverage
The whole of NP44 is in range: the town centre and every planned neighbourhood around it, the older villages the new town absorbed, and the estates on the western slopes up to Henllys and Ty Canol.

Our methods
Slab-floor detection is a discipline of its own, and Cwmbran gives us plenty of practice. We drain and charge the suspect circuit with tracer gas, then sweep the floor surface with a sensor sensitive to a few parts per million — the gas escapes at the fracture and rises straight up through the concrete. Thermal imaging cross-checks the finding against the heating layout, acoustic equipment covers incoming mains under drives and paths, and moisture meters map how far the escaped water has actually spread, which often matters as much as where it began.
A safe hydrogen-nitrogen mix escapes through the smallest defects — traced above ground to pinpoint the leak.
Non-toxicInfrared surveying reveals temperature anomalies behind floors, walls and ceilings.
Non-contactAmplifies the distinctive sound of pressurised water escaping from mains, copper and MDPE pipework.
UndergroundA flexible camera inspects wall cavities, floor voids and boxing-in through the smallest access point.
Minimal accessComparative readings across plaster, timber and concrete map water migration and confirm findings.
Evidence-gradePricing
Many leak detection companies charge £100+ per hour with no way of knowing the final bill. Our Trace & Find survey is a fixed £480 + VAT — however long it takes to find your leak.

Cwmbran FAQs
Answers specific to Cwmbran properties and how we work in the area.
In a home of that age and area it usually means a heating pipe in the screed has pinholed and is leaking warm water into the slab. Switch the heating off if pressure is dropping fast, and book a survey — we can confirm the exact spot without taking up the floor.
No. Locating is done entirely from above using tracer gas, thermal imaging and acoustic sensing. Breaking out happens only at repair stage, at the single confirmed position — typically a small opening rather than a trench across the room.
Yes — £480 + VAT covers any NP44 address, from Pontnewydd to Coed Eva, with travel from Neath included. The price is agreed at booking and does not change with the difficulty of the job.
In most cases, yes. Escape-of-water policies commonly carry trace and access cover for the reasonable cost of finding a leak, and the report we provide — location, thermal and moisture evidence, photographs — is compiled to meet that requirement without follow-up queries.
Usually within two working days. We operate Monday to Friday 9am to 5pm and weekends 9am to 2pm — ring 01639 999 999 and we will take the earliest slot that suits you.
