Water mains (supply pipe) leak detection
Where a Bridgeton block or terrace shares one supply pipe, this traces the leak along it, wherever it runs on the owners' side of the boundary.
Equipment: acoustic ground microphones and tracer gas
Under the floorboards of a Bridgeton (G40) flat, a heating or water pipe can leak unseen until a stain appears on the ceiling below. ADI Leak Detection's Hamaad Janjua works from the surface to find that pipe, marking the leak before a board is lifted, and he can carry out the repair on plumbing, heating and water mains leaks.

Hamaad Janjua works out of Giffnock, and the shortest of three Google Maps routes from there to Bridgeton is 5.8 miles, via the A77. At National Records of Scotland's latest count (2017), nearly nine in ten homes in the statistical zone named after Bridgeton were flats and most others terraced: by Scottish Water's account, both usually share a supply pipe.
ADI's engineer page lists Hamaad as a Plumbing & Heating and Water Mains Specialist, which covers the heating pipes under a flat's floorboards as well as the supply pipe that flats usually share. A flooring screw through a 22mm pipe was behind the central heating leak in Noddy's Trustpilot review, one that "was not easy to find"; Hamaad traced it, repaired it and stayed to check the system was running correctly.
Bridgeton (G40) owes its name to Rutherglen Bridge: once the bridge was built over the River Clyde in 1776, the weaving village started here in 1705 became known as Bridge Town. Glasgow Green borders it to the west, Dalmarnock to the east and south, and Calton to the north-west at Abercromby Street and London Road. Its housing is overwhelmingly flats and terraced houses, so a leak that shows in one home may begin in the flat above or on a supply pipe several homes share.
Each Bridgeton enquiry gets a conversation with the ADI office team first; the engineer is booked afterwards.
In a Bridgeton flat, the signs of a hidden leak run from a boiler that loses pressure and a ceiling stain spreading from upstairs to water on the floor after a shower, a wall that stays damp, weak taps, damp that arrives with the rain and a smell from the drains. Each of the seven is listed below beside the ADI Leak Detection investigation that tracks its cause down.
| The sign | What it usually means | The investigation |
|---|---|---|
| A brown tide mark spreading across the ceiling | Water coming down from the flat upstairs, from its bathroom or pipework, or from the roof above a top flat | Ceiling leak detection |
| You keep refilling the boiler to bring its pressure back up | Heating water escaping somewhere on the circuit, perhaps at a radiator valve or from a pipe pierced under the floor | Central heating leak detection |
| Taps running weakly, or the sound of water moving when everything is off | Possibly the shared supply pipe feeding several homes in the building | Water mains (supply pipe) leak detection |
| Water appearing on the floor after a shower | A shower tray that has cracked, a perished seal or a weeping waste joint | Bathroom leak detection |
| Blistered paint or a damp patch on an inside wall | A water pipe dripping inside the plaster or under the floorboards | Hot and cold water pipe leak detection |
| A ceiling that only drips in wet weather | Rain getting under tiles or flashing, or overflowing a gutter | Roof leak detection |
| Sewer smells, or drains backing up at ground level | A cracked drain pipe or a joint that has slipped underground | Drainage leak investigation |
Seven investigations cover the places a Bridgeton leak can start, from the supply pipe to the drains, and each card names its primary equipment.

Equipment: acoustic ground microphones and tracer gas
Tracks heating water to wherever it is escaping, from a weeping radiator to a pipe under the floor with a screw through it, the cause in the Riddrie case study.
Equipment: tracer gas, thermal imaging and pressure testing
Where hot or cold pipework disappears into plaster or under boards, this narrows the leak down to one spot before anything is cut.
Equipment: acoustic listening, thermal imaging, tracer gas and borescope
When a bath, shower, basin or toilet starts sending water into the flat below, this checks each fitting and the pipework concealed behind it.
Equipment: thermal imaging, moisture meters and borescope
Identifies what is soaking a ceiling: a neighbour's bathroom, a pipe in the floor between two flats, or the roof.
Equipment: thermal imaging, moisture meters and acoustic methods
Finds the route rain takes into a top-floor flat or a terraced house, through tiles, flashing or a gutter. ADI Leak Detection gives you the leak's location in writing, and a roofer takes on the repair.
Equipment: thermal imaging, moisture meters and drone inspection
A CCTV survey of the foul and surface water drains, with acoustic listening alongside, shows where a drain under or beside the building is losing water.

Five methods, all non-invasive, do the finding. To trace the Riddrie leak in the case study further down, Hamaad worked through thermal imaging, a damp meter, acoustic testing, a pressure test, tracer gas and an endoscope camera.
In Riddrie, tracer gas led Hamaad to the corner under the new shelves; the gas is fed into the isolated pipe and a detector finds where it escapes.
Sensors hear water forced out of a pipe; in Riddrie they picked it up under new shelving.
Water escaping from a hot pipe warms what it soaks, and the thermal camera picks that warmth out in colour.
A damp meter shows how wet plaster or timber is; in Riddrie it confirmed the corner the camera had picked out.
A camera on a flexible probe looks inside the floor void; in Riddrie, an endoscope camera pinpointed the exact spot.
Once found, a leak on a water main, a heating circuit or the household plumbing can be repaired by ADI Leak Detection, which guarantees the work, or you can call in an independent plumber instead. Roofs and structural faults sit outside the repair service: ADI locates and reports those leaks, and the repair falls to a roofer or builder.
In the Riddrie case study, the engineer who found the pierced pipe also replaced it; you can ask ADI for the same on a leaking water main, heating pipe or plumbing.
Your usual plumber is welcome to do the work, starting from the mark Hamaad leaves on site and the position in his written report. He explains the leak to you first, before any repair is discussed.
In a Bridgeton flat, who pays turns on one fitting, the boundary stop cock. Scottish Water is responsible for that stop cock, the communication pipe leading to it and the main under the street; the supply pipe on the home side, up to the stop valve in the flat, is the owners' to look after. Flats and older or terraced houses usually share that supply pipe, according to Scottish Water, so a leak on it can involve the neighbours who share it.
Check whether your buildings insurance has trace and access cover, as many policies do; it pays for the leak to be tracked down and then exposed for repair. The limit is written into each policy, so ask your insurer before booking.
One report covers the visit: the attending engineer writes it, adds photographs and video, and formats it for "Trace and Access" and "Escape of Water" insurance claims.

Hamad arrived at the prearranged time. Clearly a smart guy, he was polite, friendly and confident from the off and went on to demonstrate his understanding of our problem. Using the latest high tech gear, he lost no time in tracing the leak in our CH system, which was not easy to find. A flooring screw had penetrated a 22mm pipe. He effected the repair quickly and efficiently, cleaning up afterwards. The repair was sound and he stayed to check that the system was running correctly, with no evidence of any other problems, before going on to his next job. Our contact with the company was also good…everything explained in advance in a clear and friendly manner. We would have no hesitation in recommending their services…all good.
Read on TrustpilotI made a telephone call to ADI who were helpful and gave me a quick appointment. The engineer, Hamaad, was knowledgeable, explained what he was going to do to find my leak and let me follow his testing. He found it, repaired it and tidied up. Tested to make sure everything was back to normal. He was polite and friendly.
