The most useful leak detection tools for homeowners are your water meter, an inexpensive pin or pinless moisture meter, battery water leak alarms placed under heaters and sinks, food colouring for toilet tests, and a smart water shut-off valve for villas. Thermal cameras and acoustic detectors are professional tools that pinpoint concealed leaks.
Your water meter (free)
The single best leak detector you already own. A one-hour test with all water off tells you if a leak exists.
Water leak alarms
Small battery sensors that beep or notify your phone when they touch water. Put them under the water heater, kitchen sink, washing machine and any concealed cistern access. They are cheap insurance for apartments where a leak quickly reaches neighbours.
Moisture meters
Pin meters measure moisture in plaster and wood; pinless meters scan surfaces. They help you track whether a damp patch is growing or drying. Use them for comparison, not absolute readings, because materials differ.
Smart shut-off valves
Fitted on the main supply, these monitor flow and shut off water automatically when they detect a burst or continuous flow. They suit villas, holiday homes and anyone travelling for the summer. We can install them as part of water line work.
What professionals bring
Thermal cameras that show temperature differences behind surfaces, acoustic ground microphones and correlators that hear pressurised leaks, tracer gas for slabs and buried pipes, and line-by-line pressure testing. That is how a professional leak detection visit finds a leak to within a tile or two.
Dubai homeowner checklist
- Do a one-hour meter test with all water off before you book.
- Photograph damp patches with a coin for scale so you can see if they grow.
- Check under the water heater and behind the washing machine first; they are the quickest wins.
- If you rent, tell your landlord in writing and keep our report.
