Between the castle and the Aber Valley terraces, Caerphilly homes bury their pipework under stone, screed and steep gardens. We locate the leak first — one fixed price, nothing opened up until we know where.
Caerphilly sits in a basin ringed by mountains, and its water arrives through some long, hard-working pipe runs. We help homeowners across the town, landlords with terraces up the Aber Valley, and housing providers throughout CF83 put an exact position on hidden escapes of water before a single slab is lifted.
From Neath the drive takes about 55 minutes, so appointments are rarely more than a couple of working days out. You pay £480 + VAT, settled before we arrive, and that covers the entire detection visit — the tracer gas rig, thermal camera, acoustic listening gear, borescope and moisture meters all come as standard rather than as extras.
The paperwork matters as much as the finding. Our survey reports carry the moisture data, thermal captures and photographs an insurer wants to see, so a trace and access claim can proceed without the loss adjuster asking for more evidence.
Local knowledge
Colliery terraces climb the hillsides at Senghenydd, Abertridwr and Llanbradach, built quickly in the decades before 1914 with stone outer walls and timber floors over shallow voids. Their supplies often enter from rear lanes and gullies rather than the street, so a failed main can soak a garden wall or a neighbour's yard long before the house itself feels damp.
The town below is a different era altogether. Post-war building added Lansbury Park — one of the largest estates in Wales — while private developers filled Penyrheol, Trecenydd and Hendredenny with homes on solid concrete floors carrying copper heating loops in the screed. Failures there announce themselves as warm patches underfoot, a combi that will not hold pressure, or a water bill climbing quarter on quarter.
WHAT WE FIND IN CAERPHILLY

Our methods
Steep ground shapes how we work in Caerphilly. Escaping water follows the hillside, so we always map moisture across the full footprint of a property before trusting where the damp appears. Acoustic listening performs strongly on the valley terraces' stone construction, tracer gas travels up through concrete and tarmac to mark buried failures on the estate housing, and thermal imaging picks out live heating circuits behind plaster so we test the right pipe rather than every pipe.
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.

Caerphilly FAQs
Answers specific to Caerphilly properties and how we work in the area.
Yes — Senghenydd, Abertridwr and Llanbradach are all regular ground for us. Thick stone walls and rear-lane supply entries make these houses awkward for guesswork but well suited to acoustic and tracer gas methods, which read straight through the structure.
It is one of our most common Caerphilly call-outs. A sealed heating system that loses pressure almost always has a leak, and in homes with solid floors the escape is usually inside the screed. We pressure-test the circuit with tracer gas and mark the failure point on the floor above it.
Yes. £480 + VAT applies whether you are in the town centre, out at Machen or at the top of the Aber Valley. The figure is agreed when you book, so there is nothing to renegotiate on the day.
A full survey report: the confirmed leak location, thermal images, calibrated moisture readings and photographs of the affected areas. Most buildings insurance policies include trace and access cover, and this report is written to satisfy it first time.
We do — Saturdays and Sundays from 9am to 2pm, in addition to weekday hours of 9am to 5pm. Call 01639 999 999 and we will book you in.
