Hidden water leaks in duplexes in Al Fakhrya, Riyadh, are usually found by starting with the simplest checks and working outward. The neighbourhood's centre sits at 24.6424, 46.6826, roughly 8 km from the centre of Riyadh, with an approximate radius of 1.2 km, so a technician can treat it as a compact residential area rather than a sprawling one. The centre of Al Fakhrya sits about 595 m above sea level, which is worth noting because it shapes how water pressure behaves in the pipework of a two-storey home. The nearest wadi channel is about 2 km from the centre of Al Fakhrya, so the first checks focus on the building itself: the meter reading taken at a quiet hour, the water tank and its lid, and any damp patches on the lower walls and floor slabs.

What is left to the site visit is the part that cannot be judged from a distance. A technician will need to open inspection points, listen for flow in the walls, and test each branch in turn to pin down where water is escaping. If the water tank is in question, its condition is assessed on site; for reference, tank internal coating is priced at SAR 25–70 per m², but the area to be coated depends entirely on what is found, so no estimate is given until the tank has been measured. Whether a leak sits in the supply line, a drainage pipe, or behind a tiled wall is also decided only once the visit is under way.

To help the technician, it is useful to have a few details ready before the visit. Note when the water bill first looked unusually high, whether the meter keeps moving when every tap is closed, and which floor or wall shows dampness. Tell the technician if the duplex has been repainted or re-tiled recently, since fresh finishes can hide earlier repairs. Sharing the building's age and the location of the water tank and main shut-off valve will also save time, so the visit can go straight to the likely source of the leak.

In a duplex, the two floors often share lines, so tests are done floor by floor.

When do you need hidden water leak detection?

If you notice one of these signs in Al Fakhrya, it is a good moment to talk to the team:

• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off
• The meter keeps turning with every tap closed

Where the problem usually comes from

• A common cause: a hot line that expands and contracts with use.
• A common cause: a corroded joint inside a wall.
• A cracked pipe under floor tiles — we check this before anything else.

Tools we use in Al Fakhrya

The steps in order

1. Meter test: We stop all use and watch the meter to confirm whether water is actually being lost.
2. Line isolation: We close valves one line at a time to see which line loses pressure.
3. Acoustic listening: We follow the sound of water escaping under pressure and compare its strength between points.
4. Thermal imaging and moisture mapping: We map how far the wet area spreads behind paint and tiles.
5. Documentation: Readings, photos and the likely position go into a written report.
