Al Askan sits at 24.5738, 46.8478, roughly 23.4 km from the centre of Riyadh, and the neighbourhood spans an approximate radius of 1.2 km. That footprint is compact enough that our technicians can reach most addresses quickly, which matters when a hidden leak is wasting water under a floor or behind a wall and every hour counts. Because the district is spread out and set apart from the city core, we plan each emergency call with the route in mind before the van leaves the depot.

The centre of Al Askan lies at about 571 m above sea level, and the nearest wadi channel runs about 0.8 km away. Elevation affects water pressure in a building's supply, so we check pressure at the tank and the booster before deciding where a leak is likely to show itself. The wadi is important for a different reason: after heavy rain, ground moisture and soil movement near the channel can push water into foundations and drainage lines, so we look at damp patches on lower floors and along boundary walls, where moisture from outside can be mistaken for an internal pipe leak. Knowing the wadi is close lets us separate the two causes faster and avoid opening walls that do not need opening.

Owners often make the same mistakes in emergencies. The first is ignoring a meter that keeps turning when every tap is closed, which is one of the clearest signs of a hidden leak. The second is covering damp plaster or tiles with paint or filler, which hides the evidence and lets the leak spread. A third is assuming that a rooftop tank is sound without checking its condition; tank internal coating is priced at SAR 25–70 per m², and a failing coating can release contamination into the water long before any leak is visible. Finally, many owners wait for a large puddle before calling anyone. Acting early keeps the repair small and the damage contained.

If water is flowing, close the main valve first, then call or message with photos.

Signs that call for hidden water leak detection

The following signs are worth checking before they grow:

• The meter keeps turning with every tap closed
• A water bill higher than usual with no change in use
• A damp patch that slowly grows on a wall or ceiling

The most common causes

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

Tools and methods, and when we use them

From the first visit to the report

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.

Mistakes that cost more

• Repainting the stain while the moisture keeps coming back
• Breaking tiles at random before the line is identified
