In Cessnock (G51), where most homes are flats, ADI Leak Detection's Hamaad Janjua locates hidden leaks with non-invasive equipment and marks each one on site before a floor, wall or ceiling is opened. Should you want the leak mended, he can repair a leaking plumbing, heating or water mains pipe himself.

Hamaad Janjua's base in Giffnock and Cessnock are 5.3 miles apart on the shortest route Google Maps gives, via St Andrew's Drive. In 2017, flats made up 1,794 of the 1,867 homes in the Ibrox East and Cessnock statistical area (National Records of Scotland), so most households here probably share a supply pipe, as Scottish Water says flats usually do.
Hamaad's particular expertise lies in water mains and in domestic plumbing, the supply pipes and household pipework that a block of flats depends on, and he is Gas Safe Registered with City & Guilds qualifications. On Trustpilot, Jamie describes Hamaad as the third contractor to attend and try to locate a leak in Jamie's property: he found the source after a series of checks, then ran further tests to make sure it was not a combination of issues.
Cessnock (G51) lies south of the River Clyde and was once part of the Burgh of Govan, with Kinning Park to the east, Ibrox next door and Bellahouston Park on its southern boundary. Its housing is overwhelmingly flats, among them the curved tenement of Walmer Crescent, designed by Alexander "Greek" Thomson. In a building of flats, water from a leak can run down to the flat below before it shows, and one supply pipe often serves several flats, so the source is traced before a floor or ceiling is opened.
Before an engineer is booked, someone in the ADI Leak Detection office team talks to you about the leak.
A Cessnock flat with a hidden leak usually gives one of seven signs: a brown mark growing on the ceiling, boiler pressure that will not hold, tiles lifting by the shower, a damp wall with no pipe in sight, every tap running weaker, a top-floor ceiling wet after a downpour, or a drain smell that keeps coming back. The table gives the investigation that tracks each sign to its source.
| The sign | What it usually means | The investigation |
|---|---|---|
| A brown mark growing on your ceiling | Usually water from a bathroom or pipework upstairs or, for a top-floor flat, from the roof itself | Ceiling leak detection |
| Boiler pressure that drops again after every top-up | Most likely the heating system losing water at a radiator, a valve or pipework below the floorboards | Central heating leak detection |
| Grout crumbling or tiles lifting next to the shower | Water getting past the tray, a seal or the waste, or from pipes hidden behind tiles | Bathroom leak detection |
| A wall or skirting that stays damp with no pipe in sight | Usually pipework inside the wall or under the floor that has sprung a leak | Hot and cold water pipe leak detection |
| Every tap in the flat running weaker than it used to | The supply pipe your block shares may be leaking somewhere along it | Water mains (supply pipe) leak detection |
| A top-floor ceiling wet after a downpour | Rain getting in where the roof, its flashing or a gutter has failed | Roof leak detection |
| A drain smell that keeps coming back | Usually a crack or a parted joint in a drain or waste pipe | Drainage leak investigation |
A Cessnock flat needs the investigation that matches where its water is escaping, and each of the seven below lists the equipment ADI Leak Detection uses.
Searches the supply pipe that brings water in from the boundary stop cock, which in a Cessnock close may feed several flats before it reaches the stop valve in yours.
Equipment: acoustic ground microphones and tracer gas
Tracks down the leak behind falling boiler pressure, whether it is at a radiator, on a valve or in pipework under the floorboards.
Equipment: tracer gas, thermal imaging and pressure testing
Works along hidden hot and cold pipes in walls, floors and ceilings with listening gear and a thermal camera until the leaking section is marked.
Equipment: acoustic listening, thermal imaging, tracer gas and borescope
Tests each bathroom fitting in turn, from shower tray and bath to toilet and basin, along with the seals and boxed-in pipes, once water is getting below.
Equipment: thermal imaging, moisture meters and borescope
Finds out which bathroom, pipe or roof is behind a stain on your ceiling.
Equipment: thermal imaging, moisture meters and acoustic methods
Shows where rain is getting past the tiles, flashing, gutters or flat-roof membrane above a top-floor flat. ADI Leak Detection's job is to locate and report the leak; repairing the roof is a roofer's work.
Equipment: thermal imaging, moisture meters and drone inspection
Runs a CCTV camera through foul and surface water drains, looking for the crack or open joint behind low damp, smells or repeated blockages.
Equipment: CCTV drain survey and acoustic listening
ADI Leak Detection picks from five non-invasive methods to suit the leak, so it is found before anything is opened up. The Finnieston case study below used thermal imaging, damp meter readings, a roof space inspection and a pressure test.
The isolated pipe is filled with tracer gas, and a detector passed over the floor or ground picks up the point where the gas escapes.
Listening equipment amplifies the sound of water forcing its way out of a pressurised pipe.
Thermal imaging shows temperature, so a warm heating leak and a cold, damp patch look different on screen.
A meter pressed to a wall or floor gives a moisture reading, and a grid of readings shows where the wet is worst.
Through one small hole, a borescope's camera shows the inside of a wall cavity, a boxed-in pipe run or the void under floorboards.
Yes. ADI Leak Detection will repair a leaking plumbing, central heating or water mains pipe when you ask, and the guarantee covers all of that work; an independent plumber of your choice is the other option. Leaks through the roof or the structure are a matter for a roofer or builder to fix, once ADI has located them and reported on them.
Ask for the repair and it can be carried out by the engineer who traced the leak, so the person who found the fault is the one who puts it right.
You see the marked leak on site and hear what it is before anyone mentions a repair. The written report then records the spot, which lets a plumber of your own choosing open up in the right place.
The pipe the leak is on decides who pays. Up to and including the stop cock at the boundary of the property, responsibility lies with Scottish Water, whose part covers the water main and the communication pipe. Past it, the supply pipe that carries water into the building and on to each flat's stop valve is the owners' responsibility, and in a block it is usually shared: "Flats and older or terraced houses usually have a shared water supply pipe", in Scottish Water's words.
Trace and access cover, included in many buildings insurance policies, is meant to meet the cost of finding the escape of water and of the opening-up needed to get at it. How much a policy pays varies, so read yours, or ask your insurer, before work begins.
At the end of every ADI Leak Detection investigation, the engineer who came out writes up a report that includes photographs and video and is formatted for "Trace and Access" and "Escape of Water" insurance claims.

Hamaad from ADI came out today to investigate a leak in our en-suite. He was very knowledgeable and kept me informed the whole time as to what he was doing and why. Hamaad was polite and friendly and I would recommend this company.
Read on TrustpilotHamaad was such a great engineer. he was the 3rd contractor to attend and attempt to locate the leak in my property. 3rd time was the charm. Hammad found the source after conducting a series of checks. after finding the source he then conducted further tests to make sure it wasn’t a combination of issues. Really nice guy, very friendly and communicates his findings accurately. definitely seems to put the customer first which I really appreciated.
Read on TrustpilotHamaad was excellent! Came right on time and was straight to work and was also very informative on the process of what will happen etc. can’t recommend enough great at finding the leaks!
