Commercial water leak detection services
Investigations for buried supplies, heating circuits and hidden pipework, plus water entering through the building fabric. Tests narrow down the source before access or repairs are agreed.
Commercial water supply pipe leak detection
A commercial supply may cross a car park, branch towards separate units or disappear under a loading yard. When consumption rises without a change in trading, the leak can be outside the building even if the ground looks dry.
Signs of a water leak
- Meter movement during a verified period of no water use
- An unexplained increase in consumption or low incoming pressure
- Persistent wet ground, puddles or changes to paving
Leak detection methods
ADI uses ground microphones, tracer gas and leak correlation to investigate buried supplies. Pipe material, the available access points and site noise influence the choice of equipment.
Repairs
Water mains repairs can be quoted separately. Same-visit work depends on the location, access and time available. Confirm excavation and surface reinstatement requirements with the office.

Underfloor heating leak detection in screed floors
A concealed heating leak can affect a reception, office or changing room before there is much water to see. Keep a record of pressure loss and which areas have stopped heating properly.
Signs of a water leak
- Frequent pressure loss or a circuit that needs replenishing
- Localised damp flooring or a persistent damp smell
- Uneven heating alongside other signs of water loss
Leak detection methods
Accessible loops can be isolated and pressure tested. Thermal imaging helps follow the pipe route; acoustic equipment and tracer gas help investigate the affected area before opening the floor.
Repairs
ADI offers underfloor heating leak detection and repair. Ask for the repair scope and a separate allowance for flooring or screed reinstatement where needed.
Call 0333 567 2629Leaking pipes in commercial walls and ceilings
Office risers, ceiling voids and industrial service routes can carry several pipes through the same space. A leak may follow a beam or duct before it drips onto a desk, corridor or stock area.
Signs of a water leak
- Recurring stains on ceiling tiles or damp plaster
- Water around a service riser or beneath a pipe route
- Unexplained consumption after normal use has been accounted for
Leak detection methods
The engineer combines observations with suitable pressure tests, thermal imaging and moisture readings. Borescope inspection can help check pipework in a void without removing a large area of the finish.
Repairs
Discuss accessible pipe repairs when booking. Agree who will open and reinstate ceilings or walls, and who has authority to approve extra work on the day.
Call 0333 567 2629Commercial heating and hot water leak detection
Repeated pressure loss interrupts heating and creates extra work for the maintenance team. The investigation needs to distinguish a hidden pipe leak from a problem at accessible plant or discharge points.
Signs of a water leak
- Pressure drops recorded on the heating system
- Repeated replenishment without an identified cause
- Damp areas along radiator or heating distribution routes
Leak detection methods
Pressure testing helps separate the circuits. Thermal imaging, acoustic listening and tracer gas can then investigate pipework buried in floors or concealed behind walls.
Repairs
Heating pipework repairs can be discussed with ADI. Repairs to boilers or other plant should be agreed with the appropriate maintenance specialist after the findings are reviewed.

Washroom and changing room leak detection
A shower leak that appears during peak use can be difficult to reproduce once the room is empty. Tell the engineer which fittings were running and where the water first appeared.
Signs of a water leak
- Water below a shower or changing room after use
- Damp around WCs, washbasins or waste connections
- Recurring moisture around tiled floors and wall junctions
Leak detection methods
Dye testing helps trace escape from fittings and waste routes. Moisture readings, camera inspection and supply tests help distinguish those faults from a concealed pressurised pipe.
Repairs
The report helps you commission the right repair. Ask about pipework repairs; seals, trays, tiling and membranes may require the washroom contractor.
Call 0333 567 2629Commercial roof and building water ingress
Rainwater can travel through a roof build-up before reaching the room below. Recording when the stain appears, and the weather at the time, gives the survey a useful starting point.
Signs of a water leak
- Water ingress after rain around a roof or wall junction
- Staining beneath a flat roof or upper-floor terrace
- Recurring damp near windows, facade details or cladding
Leak detection methods
ADI investigates roof leaks using methods suited to the construction. These can include electronic leak detection, tracer gas and dye testing, with thermal drone inspection where appropriate.
Repairs
Roof and structural findings support a repair by the appropriate contractor. Discuss roof access and the proposed survey method before the visit.
Call 0333 567 2629Discuss the symptoms with ADI
Describe the water loss, affected areas and access arrangements so the office can quote the appropriate investigation.
