A leaking pipe under a Cynon Valley terrace does not need a wrecked floor to be found. Our Aberdare surveys use tracer gas, acoustic listening and thermal imaging to put a marker on the exact spot — for a fixed £480 + VAT.
The Cynon Valley is a short hop over the mountain from our Neath base, so Aberdare enjoys the same rapid response as our home patch. We take calls from Hirwaun at the head of the valley right down through Aberaman and Cwmbach — unexplained water bills, boilers that will not hold pressure, and damp that keeps returning however often it is treated.
Because we quote one fixed figure of £480 + VAT before setting off, an Aberdare survey costs the same whether the leak turns up in ten minutes under a kitchen floor or takes all afternoon to trace along a garden supply pipe. No day rates, no creeping extras.
Landlords and agents managing valley terraces use us regularly, and every visit ends with a written, photo-documented report that insurers accept for trace and access purposes.
Local knowledge
Rows of colliers' terraces from the 1860s through to the early 1900s define Aberaman, Trecynon, Cwmbach and much of central Aberdare. They were built with stone party walls, timber floors over shallow voids and, in many cases, supply pipes shared between neighbouring houses — so when one of those old runs corrodes, working out whose side of the boundary the water is escaping on becomes half the battle.
Interwar and post-war council building at Penywaun and around the valley added solid floors with embedded pipework, while Cwmaman and Llwydcoed climb the hillsides on plots with long, steeply falling service runs. Add the valley's generous mains pressure and it is little wonder that small pinholes turn into serious water loss before anyone notices a damp patch.
WHAT WE FIND IN ABERDARE
Coverage
We attend the full length of the upper Cynon Valley — Hirwaun and Penywaun in the north, the town itself with its surrounding villages, and the communities strung along the A4059 heading south. Everything in the CF44 postcode area is covered on the same fixed-price basis.

Our methods
On a valley terrace we typically begin at the meter and the stopcock, proving whether the loss sits on the supply pipe or the internal system before a single tool comes out. Acoustic ground microphones perform well on Aberdare's stone-flagged and concrete paths, tracer gas handles the deep or quiet leaks that sound alone cannot reach, and thermal imaging sweeps solid floors for the heat signature of a failed heating pipe. Moisture meters and a borescope close the case, giving your plumber a marked target rather than a mystery.
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.

Aberdare FAQs
Answers specific to Aberdare properties and how we work in the area.
Yes, and it is a situation we meet constantly in the valley's older terraces. By isolating each property in turn and using tracer gas along the shared run, we establish both where the leak is and which side of the boundary it sits on, which matters for repair responsibility.
£480 + VAT, fixed before we arrive. That covers the full Trace & Find survey — tracer gas, thermal imaging, acoustic listening, borescope inspection and moisture readings — plus the written report.
It is. We document the detection process with thermal images, moisture data and photographs in the format insurers ask for, and most buildings policies will reimburse detection costs under their trace and access section.
We do — the head of the valley is actually the closest part of CF44 to our Neath base, so Hirwaun, Penywaun and Rhigos-side addresses often get the quickest appointments of all.
Not to find the leak. The survey is entirely non-invasive; if a repair excavation is needed afterwards it happens at one confirmed point, quoted separately, rather than trial holes across the property.
