ADI Leak Detection engineer Hamaad Janjua, based in Giffnock, finds hidden leaks in the tenement flats and houses of Govanhill (G42), pinpointing each one before any floor, wall or ground is opened. Plumbing, heating and water mains leaks can be repaired by the same engineer.

Hamaad Janjua is an ADI Leak Detection engineer based in Giffnock, 3.5 miles from Govanhill by the A77. More than nine in ten Govanhill homes are flats, according to National Records of Scotland's most recent count (2017), and Scottish Water says flats usually share a water supply pipe.
Hamaad is well suited to properties with more complex pipework arrangements. He specialises in finding hidden water leaks with thermal imaging, acoustic listening equipment and tracer gas, with particular expertise in water mains and domestic plumbing systems. In a Trustpilot review, Ewan describes Hamaad tracing a leak that was coming from an upstairs neighbour's flat.
Govanhill (G42) sits on Glasgow's south side, between Pollokshields, the Gorbals, Strathbungo, Crosshill, Polmadie and Queen's Park, and its streets are lined with sandstone tenements. The south west of Govanhill is one of the most densely populated areas in Scotland. In a tenement, water escaping in one flat can show up as a stain in the flat below, so the source has to be traced before anything is opened up.
ADI Leak Detection's office team speaks to every customer before an engineer is booked.
The signs of a hidden leak in a Govanhill flat are a boiler that keeps losing pressure, a stain spreading across a ceiling, water getting through below a shower or bath, damp with no obvious source, weak water pressure, and water that only comes in when it rains. The table matches each sign to the investigation that finds it.
| The sign | What it usually means | The investigation |
|---|---|---|
| Your boiler keeps losing pressure and needs topping up | Usually a leak on the heating circuit under a floor or inside a wall, sometimes a failed valve or expansion vessel | Central heating leak detection |
| A stain spreading across your ceiling | Usually a bathroom, a pipe or the roof above, which in a tenement can be the flat upstairs | Ceiling leak detection |
| Water getting through below a shower or bath | Usually a failed shower tray, seal or trap, or the pipework behind it | Bathroom leak detection |
| A damp patch on a wall or floor with no obvious source | Often a hot or cold water pipe leaking inside the wall or floor | Hot and cold water pipe leak detection |
| Weak water pressure, or running water you can hear with every tap off | Can be a leak on the supply pipe, which flats usually share | Water mains (supply pipe) leak detection |
| Water coming in only when it rains | Usually the roof covering, the flashing or the gutters | Roof leak detection |
| Bad smells, low-level damp or repeat blockages | Often a cracked or displaced drain or waste pipe | Drainage leak investigation |
Seven ADI Leak Detection investigations are listed below, each with the equipment the engineer uses for that part of the property.
Traces a leak on the supply pipe between the stop cock at the property boundary and the stop valve inside, including a pipe shared by the flats on a close.
Equipment: acoustic ground microphones and tracer gas
Finds where a heating system is losing pressure, from pipework under the floorboards to the pipes feeding radiators through walls.
Equipment: tracer gas, thermal imaging and pressure testing
Locates leaks on the plumbing that runs inside walls, under floors and above ceilings, so only the marked spot is opened.
Equipment: acoustic listening, thermal imaging, tracer gas and borescope
Tests shower trays, baths, seals and the concealed pipework behind them when water is getting into the floor or through to the room below.
Equipment: thermal imaging, moisture meters and borescope
Follows a ceiling stain back to its source, whether that is a bathroom, a pipe or the roof above.
Equipment: thermal imaging, moisture meters and acoustic methods
Finds where rainwater is getting in through the roof covering, flashing or gutters. ADI Leak Detection locates and reports roof leaks, and the repair is for a roofer.
Equipment: thermal imaging, moisture meters and drone inspection
Checks drains and waste pipes for cracks and displaced joints with a camera survey, which is how a drain leak behind damp or smells gets found.
Equipment: CCTV drain survey and acoustic listening
ADI Leak Detection finds a hidden leak with five non-invasive methods. In the Crosshill case study further down this page, damp meter and thermal imaging readings showed where to open the wall.
Hydrogen tracer gas goes into the isolated pipe and is picked up at the surface where it escapes, through screed, timber, tile or soil.
Ground microphones pick up the sound of water escaping from a pipe under pressure.
The camera shows the heat pattern of a hot water or heating leak through plaster and screed.
Pin and pinless meters map how far damp has spread, which tells a live leak from an old stain.
A small camera on a flexible lead looks into floor voids, walls and ceilings through a small access point.
ADI Leak Detection repairs leaks on plumbing, central heating and water mains, and all ADI Leak Detection repair work is guaranteed. You can also have an independent plumber carry out the repair. Roof and structural leaks are located and reported, and their repair is for a roofer or builder.
Where you want the leak fixed, the engineer who traced it can carry out the repair, so one engineer sees the job through from the first test to the finished repair.
The engineer marks the leak on site and explains it to you before any repair is discussed, and the written report records where it is, so an independent plumber can go straight to it.
Who pays depends on where the leak is. Scottish Water is responsible for the water main in the street and the communication pipe up to and including the stop cock at the property boundary, and property owners are responsible for the supply pipe from there to the stop valve inside the home. Scottish Water notes that flats and older or terraced houses usually have a shared water supply pipe.
Many buildings insurance policies include trace and access cover, which pays for finding the source of an escape of water and for the work needed to reach it. The limit is the part that varies, so check your own policy.
Every ADI Leak Detection investigation ends with a written report by the engineer who attended, supported by photographs and video and formatted for "Trace and Access" and "Escape of Water" insurance claims.

Hamaad was very prompt, friendly and professional. He attended my property to track and trace a leak coming from an upstairs neighbour’s flat. He was very courteous and knowledgeable, gaining the complete confidence of my neighbour and tracked the leak quickly, giving a clear explanation of the necessary repair. His input was invaluable, in what could otherwise have been quite a difficult conversation.
Read on TrustpilotWe have just had Hammad out and he was fantastic. He rang me yesterday to confirm the booking and arrived right on time. He was very professional. He was also very friendly and easy to talk to. He managed to locate our leak which was under the concrete in our kitchen floor. He told me right throughout what he was doing and why. He fixed the leak and did a very thorough job. He cleaned up after he was done and I can't recommend him enough. I would be happy for him to do jobs in my house again any time.
Read on TrustpilotHamaad from ADI was great. He was very thorough with his work and communicated everything very clearly. He was able to locate the leak and provided a detailed report that could be shared with my insurer. He went above and beyond to answer questions about my insurance claim from both me and my insurer. I'd highly recommend their services.
