Leak DetectionEliteWhether the water is vanishing beneath a Georgian townhouse in the Watton or somewhere along a quarter-mile of farm supply pipe, we trace it without digging first. Fixed fee of £480 + VAT, agreed before we cross the Beacons.
Brecon and its surrounding countryside present some of the most varied leak-detection work in Wales. In a single week we might trace a heating fault beneath a listed townhouse near the cathedral, then spend the afternoon walking a field with a ground microphone to find where a farm's private supply is bleeding away.
The fixed price of £480 + VAT holds across all of it. Rural jobs with long pipe runs take longer, but that is our risk, not yours: the quote we give on the phone is the figure on the invoice. We survey 24 hours a day, seven days a week, which suits farms where early mornings are the only quiet window.
Homeowners, smallholders, holiday-let owners and estate managers across LD3 all receive the same insurance-grade documentation: thermal imagery, moisture readings and photographs compiled into a report your insurer can act on.
Brecon's core is one of the best-preserved Georgian townscapes in Wales: tall townhouses along the Watton, the Struet and Llanfaes with solid rubble-stone walls, lime plaster and cellars, many of them listed. Invasive investigation in buildings like these is expensive and often needs consent, which makes non-invasive tracing not just preferable but practically essential. Old lead runs, Victorian additions and layer upon layer of altered plumbing give water plenty of quiet routes to travel before it surfaces somewhere misleading.
Outside town the picture changes completely. Stone farmhouses and barn conversions across the Usk valley frequently draw water from private springs or boreholes, fed through hundreds of metres of alkathene or older galvanised pipe crossing fields and yards. A split anywhere along that run drains the source, starves the header tank and soaks ground nobody ever walks, and pinpointing it by eye is hopeless.
WHAT WE FIND IN BRECON
From the town itself we range across the whole LD3 area: the villages beneath the Beacons, the Usk valley settlements east towards Bwlch and Llangorse, Talgarth under the Black Mountains, and west to Sennybridge and the upper Usk.

Rural Powys is where tracer gas earns its keep. We charge the suspect pipe with a safe hydrogen-nitrogen mix and walk the route with a sensing probe; the gas escapes at the fracture and rises through soil, tarmac or flagstones to give us a surface reading, even on runs several fields long. In Brecon's older buildings we lean on acoustic listening and thermal imaging instead, methods that respect lime plaster and historic fabric, with a borescope and moisture meters confirming the source before anyone considers opening up.
A safe hydrogen-nitrogen mix escapes through the smallest defects and is 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.

Answers specific to Brecon properties and how we work in the area.
Yes, this is one of our specialities in Powys. We pressure-test the supply run, then trace it with gas and acoustic equipment to find the failure point, whether that is 20 metres from the house or 400 metres up the hill. You get a marked location and a report, so the repair is one small excavation.
Entirely. Detection itself involves no opening-up: tracer gas, thermal imaging, acoustic listening and surface moisture readings are all non-destructive, which is precisely why surveyors dealing with listed buildings favour this approach.
It does. Every address in LD3 is charged at £480 + VAT for the full Trace & Access survey, whether you are on Ship Street or a hill farm above Sennybridge. Longer pipe runs simply mean we allow more time.
Usually, yes. Buildings policies commonly include trace and access cover for locating hidden water leaks, and the report we hand over, containing thermal images, readings and photographs, is written to satisfy that claim process. Note that some private supply pipework falls outside standard cover, so it is worth checking your schedule.
Brecon is about 50 minutes from us, so we can usually offer an appointment within a couple of working days, often sooner if a leak is active. Call 0333 772 4776 and we will find the earliest slot.
