Central heating leak detection in Crawcrook
Central heating leak detection finds leaks in heating pipes and underfloor heating using tracer gas, thermal imaging and pressure testing.

What are the signs of a central heating leak?
Falling boiler pressure, frequent radiator bleeding or a warm floor patch can indicate a leak. ADI Leak Detection Crawcrook traces and marks it from the surface before any floor comes up.
Topping up the boiler hides a heating leak while it carries on out of sight, so watch for these signs:
- Boiler pressure dropping and needing the filling loop every week
- A radiator or a run of underfloor heating that never quite warms up
- Bleeding air out of radiators far more often than you used to
- A warm patch on the floor, or a skirting board that has started to lift
- Damp in a downstairs ceiling under a bathroom radiator
Where do central heating leaks occur in Crawcrook?
The team investigates concealed heating leaks after boiler checks leave continuing pressure loss unresolved.
- In the 2021 Census, terraces accounted for 38.2% of accommodation in the combined Crawcrook and Greenside built-up area. Greenside's character description also records miners' terraces and stone cottages.
- For a heating enquiry, describe the current circuit and any extension, radiator move or conversion that may have altered it. Give the findings of earlier boiler or circuit checks and note when the pressure changes.
- If damp or an unexpected warm patch appears on a floor, identify its position relative to the known heating route. Explain which rooms are occupied or difficult to reach so access can be discussed.
- These observations allow the investigation to focus on the remaining evidence within the actual installation.
How does ADI Leak Detection Crawcrook find a central heating leak?
The engineer pressure tests the circuit, maps the pipes with thermal imaging and follows tracer gas to the leak, then confirms it before anything is lifted. Once the position is found, the engineer explains it on site before any repair is discussed.
Pressure testing measures water loss from the heating circuit. The circuit is isolated before the test, and tracing starts once the rate of loss is known.
Thermal imaging reads the heat of the circuit through the floor finish and draws the layout of the pipework, including underfloor heating loops.
Hydrogen tracer gas passes through the heating pipe leak and rises through screed, timber and tile. The system is drained before it is charged with tracer gas.
A tracer gas probe detects the escape above the heating pipes as the engineer moves it across the floor, usually locating it within a few centimetres.
Moisture readings and a borescope inspection through a small access point confirm the heating leak position before anything is lifted.
Why does a boiler keep losing pressure?
Boiler pressure loss usually points to a hidden leak, and the investigation finds where.
Why does boiler pressure drop?
A leak on the heating circuit is the common cause: a sealed system only loses water if it is escaping somewhere. A failed pressure relief valve or a waterlogged expansion vessel can do the same thing without a drop of water showing indoors, and the investigation is what tells you which of the three it is.
Why does topping up the boiler fail to fix a heating leak?
Every top up puts fresh, oxygenated water into a sealed system, which speeds up corrosion in the radiators and the boiler itself. Meanwhile the leak carries on under the floor, so a small repair now turns into a lifted floor and a damaged ceiling later.
How does ADI Leak Detection Crawcrook investigate boiler pressure loss?
Tracer gas goes into the drained circuit, thermal imaging maps the pipe runs under the floor, and the system is pressure tested zone by zone until the loss is isolated. Once the leak is found, its position is marked before anything is lifted, and the report says plainly whether it was the pipework, the valve or the vessel.
What happens after a central heating leak is found?
Central heating leak repairs by ADI Leak Detection Crawcrook are guaranteed. If a floor must come up, the engineer opens the smallest area that reaches the pipe.
Every leak detection visit ends with a written report by the engineer who attended, with photographs and video, formatted for trace and access and escape of water insurance claims.
- The leak position marked on site and explained before you decide anything
- Photographs and video in the written report
How do you arrange central heating leak detection in Crawcrook?

If you are unsure which investigation you need, describe what you can see when you call and the advisor will tell you.
Same or next day depending upon engineer availability.
What do people ask about central heating leak detection?
Three questions come up before a central heating leak survey: how long it takes, whether the floor comes up and whether underfloor heating can be traced.
How long does a central heating leak detection visit take?
It depends on the property and how much of the system has to be tested, so the advisor gives you an estimate when you book.
Does central heating leak detection mean lifting the floor?
Floor lifting is needed only at the leak position, and only if you want it repaired. The leak is traced from the surface.
Can ADI Leak Detection find a leak on underfloor heating?
Underfloor heating leak detection uses thermal imaging to map the loops and tracer gas to pinpoint the failure.
