Whether the water is vanishing under a Maindee terrace or a new-build at Glan Llyn, we find the exact spot before anyone reaches for a breaker. Fixed fee, no damage, report included.
Newport's housing tells the story of its docks and its steelworks, and so do its leaks. We survey homes and commercial premises across the city for owners, landlords and letting agents who want a confirmed leak position — not an invoice for ripped-up flooring that found nothing.
The M4 puts Newport roughly an hour from our workshop, close enough that we treat the city as core territory rather than an occasional trip. Booking us brings the complete detection kit — tracer gas, thermal camera, acoustic ground microphone, borescope and calibrated moisture meters — for a single fixed £480 + VAT agreed before we set off.
Each job finishes with a written report built for insurers: the located escape point, the evidence trail behind it, and the thermal and photographic records. If your buildings policy carries trace and access cover, that document is what unlocks it.
Local knowledge
The tight terraced grids of Pillgwenlly, Maindee and Baneswell were thrown up for dock and railway workers in the late 1800s, and their original supplies — frequently lead, frequently shared between two or three houses — are well past their design life. Add suspended timber ground floors and a century of amateur plumbing alterations, and you get damp skirting boards three rooms from the failed joint.
Post-war Newport built at scale: the estates at Bettws, Ringland and Alway sit on solid concrete floors with heating pipework set directly into the screed, where a corroded elbow can bleed into the slab for months unseen. At the other end of the timeline, modern developments at Glan Llyn and Jubilee Park in Rogerstone use plastic barrier pipe that rarely corrodes but fails abruptly at mechanical fittings — usually behind a kitchen kickboard or an upstairs bath panel.
WHAT WE FIND IN NEWPORT
Coverage
We take in the whole city and its edges — from the Gaer and Stow Hill through the centre to Lliswerry and Somerton, north to Malpas, Bettws and the Roman streets of Caerleon, and west across Rogerstone, Bassaleg and Duffryn.
Postcode areas covered: NP10 · NP18 · NP19 · NP20
Our methods
On Newport's older streets the giveaway is often a meter that creeps overnight, so we begin with pressure and flow testing to prove which circuit is losing water. Acoustic correlation then traces failures along the shared supplies running under terraced pavements; tracer gas pinpoints escapes below the concrete slabs of the post-war estates; and thermal imaging separates a genuine heating leak from plain condensation — a distinction that matters in the city's colder solid-walled homes.
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.

Newport FAQs
Answers specific to Newport properties and how we work in the area.
Yes — every NP10, NP18, NP19 and NP20 address is covered at the same £480 + VAT, from riverside flats in the centre to village properties out at Caerleon and Bassaleg. There are no travel supplements.
Very possibly. In Newport's Victorian terraces, pipework often runs along or through party walls, and a neighbour's failed fitting can present as damp on your side. Moisture profiling and thermal imaging tell us whether the moisture is plumbing-fed or weather-related, and whose side it starts on.
Most take between two and four hours. A straightforward heating leak under a slab might be cornered quickly; a shared Victorian supply pipe takes longer. Either way the price stays at £480 + VAT — time on site is our problem, not yours.
Usually, yes. The report we hand over documents the leak position with thermal, moisture and photographic evidence, which is exactly what a trace and access claim requires. Check your buildings policy — the cover is standard on the majority of them.
We are. Weekend hours run 9am to 2pm on both Saturday and Sunday, alongside 9am to 5pm Monday to Friday. Ring 01639 999 999 to secure a slot.
