A leak under a Brynmill terrace behaves nothing like one inside an SA1 apartment block. Our engineers pinpoint both without opening up your property — for a fixed £480 + VAT agreed before anyone lifts a tool.
Swansea generates more leak enquiries than anywhere else we serve, simply because of its size and the variety of its buildings. From student lets in Brynmill to waterfront apartments in the Maritime Quarter and family semis in Sketty, we trace hidden water escapes across the city for owners, landlords, block managers and letting agents.
With Neath only twenty minutes up the road, Swansea appointments are easy to arrange at short notice — usually the same or next working day, with weekend slots available as well. One engineer arrives carrying the complete kit: tracer gas, thermal camera, acoustic ground microphone, borescope and moisture meters, so the fault is confirmed in a single visit.
Every survey closes with documentation an insurer will take seriously: annotated thermal captures, moisture maps and a written account of where the water is escaping and why. If you are claiming under trace and access, that evidence does the heavy lifting for you.
Local knowledge
The terraces of Uplands, Brynmill, Mount Pleasant and St Thomas went up in the late 1800s when the copper and docks trades were booming. Behind their solid masonry sit generations of altered plumbing — lead swapped for copper, copper teed into plastic — and suspended timber floors that let escaping water travel a long way from the pipe that actually failed. In the busy HMOs around the university, constant demand turns a small weep into a serious bill remarkably quickly.
The picture changes across the city. The 1920s council-built streets of Townhill and Mayhill sit on steep gradients served by long, ageing supply pipes; interwar and post-war semis in Sketty, Killay and West Cross often carry heating circuits set into solid floors; and the apartment blocks of SA1 run pressurised communal systems where a fault on one level surfaces two flats away. Out at Mumbles, salt-laden air steadily shortens the life of external pipework and fittings.
WHAT WE FIND IN SWANSEA
Coverage
Our patch takes in the whole city and its suburbs — the docklands and Enterprise Zone in the east, Morriston and Llansamlet along the M4 corridor, the university districts, the western suburbs out through Killay to Gorseinon, and the coast road through West Cross to Mumbles.

Our methods
Dense terraced streets reward acoustic work: escaping mains water has a signature sound, and our ground microphones follow it beneath pavements and solid floors without disturbing either. Where city-centre background noise drowns that out, we switch to tracer gas — a harmless hydrogen-nitrogen mix that rises through tarmac, tiles and screed to flag the precise failure point. Thermal imaging maps heating faults inside apartment blocks, and the borescope inspects wall cavities and floor voids through openings only a few millimetres across.
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.

Once located, repairs are quoted separately — every repair varies by leak type, pipework and access.
Priced individually to reflect the size, complexity and requirements of each project.

Swansea FAQs
Answers specific to Swansea properties and how we work in the area.
Usually the same or next working day — Neath to most of Swansea is a twenty-minute drive. We operate seven days: 9am to 5pm on weekdays and 9am to 2pm at weekends. Call 01639 999 999 and we will offer the earliest available slot.
Yes. Leaks in apartment buildings rarely surface where they begin. By combining moisture mapping, thermal imaging and pressure testing across the affected flats we identify the source pipe and the dwelling it serves, then document it clearly for the managing agent and the block's insurer.
No — avoiding that is the whole purpose of detection. Everything is located from the surface using tracer gas, acoustics, thermal imaging and a borescope. You receive a marked position accurate enough for any repair to be one small opening rather than a search.
In most cases, yes. Buildings policies commonly include trace and access cover, which pays for finding a hidden leak and making good afterwards. Our report — thermal evidence, moisture readings, photographs and the located position — is written to support exactly that claim.
We do. West Cross, Mumbles and the SA3 coastal strip are covered at the same fixed £480 + VAT, as is every address from SA1 through to SA7.
