Leak Detection · Scunthorpe & North Lincolnshire
A damp patch that keeps coming back, boiler pressure that drops every week, a water bill that has doubled for no reason. We isolate and prove where the water is going, then repair it with the least disruption possible.

Service overview
The expensive part of a hidden leak is almost never the repair — it is the searching. Floors lifted in the wrong room, plasterboard cut out on a guess, tiles broken to expose sound pipework. A methodical detection process isolates the circuit, proves where the loss is, and confines the opening-up to one small area.
Systematic leak tracing on mains cold, hot, heating and waste: pressure isolation testing, section-by-section elimination, thermal and moisture assessment, drain and waste testing, and full repair once the source is confirmed.
Homeowners, landlords and letting agents across Scunthorpe, Brigg, Messingham, Scotter, Kirton Lindsey, Barton-upon-Humber, Hull, Grimsby and Doncaster — including insurance-related trace-and-access work where a written report is required.
When boiler pressure keeps dropping, when a damp patch keeps returning after redecorating, when the water meter turns with every tap closed, when a floor is warm in one strange spot, or when there is a persistent musty smell with no visible source.
Escaping water damages structure, insulation and electrics continuously and quietly. It is also the most common domestic insurance claim in the UK, and most insurers require a documented trace before they will authorise access work.
What goes wrong
Different symptoms point to very different parts of the system. This is what they usually mean.
Either a genuine system leak or a failed expansion vessel forcing water out through the pressure relief valve. Testing distinguishes them in minutes — topping up hides both.
Almost always a live leak rather than historic damp. Water tracks along joists and appears metres from its source, which is exactly why guessing fails.
A leaking heating pipe under screed or a solid floor. It needs tracing accurately, because opening a concrete floor in the wrong place is a serious and expensive mistake.
A supply-side leak between the boundary stop tap and the property, or a passing internal fitting. Isolation testing tells us which side of the wall it is on.
Shower tray perimeter, waste seal, trap union or a pinhole in a feed. All four look identical from below and are told apart by testing, not by opinion.
A long-running low-volume leak into a void or under a floor. These do the most structural damage precisely because nothing visible ever appears.
Our process
Elimination, in order, so the answer is proven rather than assumed.
When it started, what changed, how fast pressure or damp develops, what work was done recently. It narrows the search considerably.
Mains, hot, heating and waste isolated in turn. Watching which circuit loses pressure removes most of the property from the search immediately.
Suspect sections pressure tested and held. A section that holds is eliminated; a section that drops is confirmed and measured.
Moisture readings and surface temperature checks map where water is actually sitting, versus where it first appeared.
Findings and the recommended repair given to you in writing — in the detail insurers ask for where a claim is involved.
Minimum access opened, pipework repaired or replaced, system pressure tested again and the area reinstated tidily.
Benefits
One small access point instead of a lifted floor and three holes in the ceiling. The making-good bill is usually the biggest saving.
Proving the source means fixing the actual failure, not the nearest joint that looked suspect.
Written findings, photographs and test results in the format most insurers require for trace-and-access cover.
Every week a slow leak runs, more plaster, insulation and timber gets written off. Speed genuinely matters here.
If the cause is condensation, rising damp or a roof defect rather than plumbing, we will tell you plainly rather than sell you a plumbing repair.
Same engineer traces it and fixes it, so nothing gets lost handing over between two firms.

In detail
A short guide to the checks we run and what each one rules in or out.
If the pressure falls only when the system heats and the pressure relief pipe outside drips, the expansion vessel has usually lost its charge — that is a recharge or replacement, not a leak hunt. If pressure falls steadily even cold, there is a genuine loss of water somewhere in the circuit. We test the vessel charge before we go looking for pipework.
With every internal outlet closed, a turning water meter means the loss is upstream. We isolate at the internal stop tap: if the meter stops, the leak is inside; if it keeps turning, it is on the supply pipe and your water supplier may share responsibility for the repair depending on where the failure sits.
Screeded pipework is traced by section isolation on the manifold and surface temperature mapping, so we can open one small area of floor rather than several. Each loop is tested and pressure held individually before anything is cut.
Tray perimeters, waste seals and trap unions are tested independently by wetting each in isolation and watching below. It is unglamorous and it is the only reliable way to tell four near-identical symptoms apart.
Waste leaks only appear when something is used, which is why they seem intermittent. We test each appliance separately under full flow rather than a token trickle.
Condensation on cold pipework, penetrating damp at a defective sill, a slipped tile or a blocked gutter can all look exactly like a plumbing leak. If our testing eliminates the plumbing, we say so and point you at the right trade instead.

Detection is charged at our standard fixed diagnostic rate, confirmed with you before we attend. Any repair is quoted separately in writing once the source is proven.
Only where testing has confirmed the leak is beneath them, and only the smallest area needed. The whole purpose of methodical tracing is avoiding speculative opening up.
Sometimes. It can equally be a failed expansion vessel pushing water out of the pressure relief valve. We test the vessel first, because that check takes minutes and rules out half the possibilities.
Yes. We supply written findings with test results and photographs, which is what most insurers require to authorise trace-and-access and repair costs.
Yes — by isolating circuits and mapping surface temperature to narrow the location before any breaking out. It is slower work but far cheaper than opening a floor speculatively.
We work Monday to Friday, 8am to 5pm, and prioritise active leaks. Where a slot is free we aim for the same working day across North Lincolnshire, and usually same or next working day for Hull, Grimsby and Doncaster.
Usually, once the source is confirmed and access allows. Where a repair needs a specific part or a further trade, we leave the system safe and give you a fixed-price plan in writing.
Yes — 12-month workmanship guarantee in writing on every repair we carry out.
