Between Pembroke's medieval walls and Pembroke Dock's Victorian grid, this corner of Pembrokeshire holds some of the oldest plumbing puzzles we see. We solve them without harming the fabric — £480 + VAT, however long the search takes.
Pembroke and Pembroke Dock sit at the far western edge of our patch, so we treat surveys here as proper expeditions: symptoms discussed by phone beforehand, every instrument loaded on the van, and enough time reserved to see the job through. Homeowners, landlords and holiday-let owners across SA71 and SA72 all pay the same fixed £480 + VAT.
The two towns could hardly be more different to work in. Pembroke is essentially one long medieval street beneath the castle, its houses set on narrow burgage plots with immensely thick walls and centuries of alteration behind the render. Pembroke Dock, laid out for the Royal Dockyard in the early 1800s, is a disciplined grid of stone terraces climbing towards Pennar and Llanreath. Both hide pipework in places a drill should never go near — which is why a non-invasive survey is the correct first move.
Where damage has already been done, the survey doubles as claim evidence. We hand over a report containing the located position, thermal captures, moisture data and photographs — the file a loss adjuster expects to see when trace and access cover is invoked.
Local knowledge
Main Street and the lanes off it include listed and conservation-area buildings where exploratory holes are simply not an option. Limestone walls the best part of a metre thick absorb escaping water and release it somewhere else entirely, so visible damp is a poor guide to where the fault actually lies. Supplies here can be very old indeed, and internal plumbing has typically been re-routed with every change of use across two centuries. Monkton, over the mill pond, shares the same medieval bones.
Pembroke Dock's dockyard-era terraces bring their own habits: shared party-wall plumbing, slate damp courses long past their best, and service pipes running beneath front rooms straight off the pavement. Up at Pennar and Llanreath the weather off the Haven works on external fittings all year round, while the modern estates and the village of Lamphey to the east add screeded floors and plastic systems to the mix.
WHAT WE FIND IN PEMBROKE
Coverage
We work both towns and the country around the lower Haven: Pembroke with Monkton in SA71, out to Lamphey and the coast at Freshwater East, and Pembroke Dock in SA72 including Pennar, Llanreath and Bufferland.

Our methods
Heritage fabric changes how we work, never whether we can. Tracer gas passes freely through lime mortar, flagstones and cobbles, so a buried supply beneath a listed frontage can be tested without touching a single stone. Acoustic listening performs the same trick through solid floors, thermal imaging reads heating circuits straight through plaster, and moisture profiling maps how far the escape has travelled — meaning any repair opening is made once, in the right place, with far less for a conservation officer to worry about.
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.
A complete leak detection survey with the right equipment for your property.
no hourly rates · no hidden costs
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.
Answer a few quick questions and we will point you to the right fixed price.
Pembroke FAQs
Answers specific to Pembroke properties and how we work in the area.
Yes — SA71 and SA72 are part of our standard coverage. The journey from Neath takes about an hour and a half, so we book a generous appointment window in advance and complete the whole investigation in one visit.
That is precisely what the method is designed for. Nothing is opened up during detection: tracer gas, acoustic listening, thermal imaging, moisture meters and the borescope all read the building from its surfaces. You end up with a marked fault position so any consented repair work is minimal and targeted.
We do — both towns, plus Llanreath, Bufferland, Monkton, Lamphey and Freshwater East, all at the same fixed £480 + VAT.
The report is part of the £480 + VAT — never an extra. It documents the fault position, methods, damage and supporting instrument evidence in the form insurers require for trace and access claims, which most buildings policies include.
Weekdays 9am to 5pm and weekends 9am to 2pm — useful for holiday lets, where a Saturday morning visit between guests is often the practical choice. Call 01639 999 999 and we will plan around your calendar.
