Water mains (supply pipe) leak detection
Pinpoints a leak on the private supply pipe, which at a house can run beneath a lawn, a drive or the floor itself, and marks where to dig.
Equipment: acoustic ground microphones and tracer gas
Leak detection Dumbreck, Glasgow by ADI Leak Detection
A stained ceiling in a Dumbreck (G41) flat or a wet lawn outside a house can both mean a hidden leak. Based in Giffnock, ADI's engineer Hamaad Janjua pinpoints it from the surface, so there is one place to open. ADI can then repair it with a guarantee if it is in the heating, the plumbing or the supply pipe.
- After over 1,600 reviews, ADI's Trustpilot score is 4.7 out of 5
- Water Leak Detection Service of the Year is a title ADI has won four times from the Corporate Livewire Prestige Awards: 2019, 2021, 2023 and 2026
- Every visit ends in a trace and access report, backed by photographs and video

Hamaad, Your Dumbreck Leak Detection Expert
Three miles of road, via Mansewood Road and the B769, separate Dumbreck from Giffnock, Hamaad Janjua's base. In the statistical area that covers Kingston West and Dumbreck, about three homes in four were flats at the last count by National Records of Scotland, in 2017. Scottish Water's guidance is that a flat usually has a shared water supply pipe.
Hamaad's title at ADI is Plumbing & Heating and Water Mains Specialist, and his expertise covers both the supply pipe and the plumbing inside a flat or house; he is Gas Safe Registered and City & Guilds qualified. Simon B. describes on Trustpilot how Hamaad found a leak on the water main and then tested the inside of the building for leaks too.

Dumbreck Leak Detection Services
Dumbreck (G41), a conservation area south of the River Clyde, lies across the M77 from Pollokshields and next to Bellahouston and Bellahouston Park. Alongside its flats, the statistical area that includes Dumbreck held almost 350 detached and semi-detached houses in 2017. So a hidden leak here may be on a house's supply pipe or coming through a ceiling from the flat above, and each calls for a different investigation.
Flat or house, every Dumbreck caller speaks to ADI's office team before an engineer is booked.
What leak detection in Dumbreck includes
- Five ways of finding the leak without opening anything up: acoustic listening, tracer gas, borescope cameras, thermal imaging and moisture meters
- A mark on the floor, wall or ground showing where the leak is, made before any opening
- The attending engineer's findings, photographed, filmed and written up for "Trace and Access" and "Escape of Water" claims
- A guaranteed repair if the leak is on the heating, the plumbing or a water main
- Any roof or structural leak pinpointed and put in writing
What are the signs of a hidden leak in a Dumbreck home?
The signs of a hidden leak in a Dumbreck home range from a stained hallway ceiling and a shower tray sinking underfoot to a boiler that needs repressurising, damp skirtings, a wet patch on a path or lawn, fresh stains upstairs after heavy rain and an outside drain that keeps overflowing. Beside each sign sits the investigation that finds where the water is coming from.
| The sign | What it usually means | The investigation |
|---|---|---|
| Damp or flaking plaster on a hallway ceiling | Often the bathroom of the flat above, as in this site's West End case study | Ceiling leak detection |
| A shower tray that sinks or moves underfoot | Failed seals letting water soak into and weaken the floor below the tray | Bathroom leak detection |
| A boiler that needs repressurising more often than it did | Somewhere the heating circuit is losing water: a weeping valve, a corroded radiator or a pipe in a solid floor | Central heating leak detection |
| Skirting boards or floorboards that stay damp to the touch | A leaking cold feed or hot water pipe hidden in the floor void or wall | Hot and cold water pipe leak detection |
| A wet patch on a path or lawn that stays wet in a dry spell | Can be the underground supply pipe, which is the owner's to repair | Water mains (supply pipe) leak detection |
| New stains upstairs after heavy rain | A slipped tile, failed flashing or overflowing gutter | Roof leak detection |
| A gully or drain outside that keeps overflowing | An underground drain cracked or pulled apart | Drainage leak investigation |
Which leak detection service does your Dumbreck leak need?
Your Dumbreck leak needs whichever of these seven ADI investigations covers where the water is escaping, and under each one is the kit the engineer uses.
Central heating leak detection
When the boiler keeps needing more pressure, the heating circuit is tested and the leaking radiator, valve or buried pipe is pinned down.
Equipment: tracer gas, thermal imaging and pressure testing
Hot and cold water pipe leak detection
Locates a leak on the cold supply or hot water pipework inside the fabric of the building, so the only hole made is at the marked spot.
Equipment: acoustic listening, thermal imaging, tracer gas and borescope
Bathroom leak detection
Checks a bathroom or en-suite seal by seal and pipe by pipe, concealed cistern and boxed-in waste included, when damp spreads to the floor or room below.
Equipment: thermal imaging, moisture meters and borescope
Ceiling leak detection
Follows the water marking a ceiling up to where it began: the roof, a bathroom or pipework on a higher floor.
Equipment: thermal imaging, moisture meters and acoustic methods
Roof leak detection
Finds the tile, flashing, gutter or flat-roof membrane letting rain in. ADI locates and reports the leak, and a roofer is the one to repair it.
Equipment: thermal imaging, moisture meters and drone inspection
Drainage leak investigation
Inspects the drains, foul and surface water alike, on CCTV, to show where a pipe has cracked or a joint has opened.
Equipment: CCTV drain survey and acoustic listening
How does ADI find a hidden leak before anything is opened up?
Five non-invasive methods are open to an ADI engineer. On the West End job in the case study, thermal imaging and a damp meter found the wet areas, pressure tests checked the supply, and a seal test found the failure.
Tracer gas
With the pipe isolated, tracer gas goes in, and the engineer sweeps a detector over the surface to find where it emerges.
Acoustic listening
A pressurised leak makes a noise of its own, and acoustic equipment follows it to the source.
Thermal imaging
A thermal image turns temperature into colour: a hot pipe leak shows warm, soaked plaster cold.
Moisture meters
Damp meter readings tell a wet wall from a dry one and mark where the water damage ends.
Borescope cameras
The borescope's probe bends round joists and pipe runs, sending back pictures from places no one can see into.
Can ADI repair the leak once it is found?
Once ADI Leak Detection has found a leak on a heating system, the plumbing or the supply pipe, it can repair it and guarantee the work. Or you can hand the repair to an independent plumber. With roof and structural problems, ADI's role is to pinpoint and report them, and the repair belongs with a roofer or builder.
Leak repairs by ADI Leak Detection
If ADI does the repair, the engineer who did the tracing can carry it out, having already seen the pipework, the readings and the mark.
Repairs by your own plumber
Your own plumber can take over from the engineer's mark and written report, which between them show where the leak is. On the West End job in the case study, Hamaad showed the customer the failed seals on site.
Who pays to find and fix a leak in a Dumbreck flat?
The boundary stop cock splits the pipework, and the leak's side decides who pays. Scottish Water's side ends with the stop cock and takes in the water main in the street and the communication pipe; the owner answers for the supply pipe beyond it, to the indoor stop valve. In 2017 the Kingston West and Dumbreck statistical area had about 1,500 flats and 100 terraced houses, and Scottish Water's FAQ says "Flats and older or terraced houses usually have a shared water supply pipe".
Your buildings insurance
Under trace and access cover, which many buildings policies include, the insurer meets the cost of finding the leak and getting to it, within a limit that varies by policy.
Your leak detection report
Your insurer receives the report as written by the engineer who came out, with photographs and video, in a form fit for "Trace and Access" and "Escape of Water" claims.
