Do you have a damp patch on a wall, a sudden jump in your water bill, or a soft spot in the garden that never dries out? In Al Mlqa, a neighbourhood made up mainly of villas in northern Riyadh, these are common signs of a hidden leak. The area's centre sits at 24.8010, 46.6007, about 12.3 km from the centre of Riyadh, and it covers an approximate radius of 4.4 km. Its centre is roughly 666 m above sea level, and the nearest wadi channel lies about 2.7 km away. Because villas here often have long underground supply lines, rooftop tanks and garden irrigation, a leak can run for weeks before it shows on the surface, so a structured check is worth arranging early.

The inspection for a villa usually starts with a review of your meter reading over a quiet period, when no taps or appliances are in use, to confirm that water is still moving through the system. The technician then listens along pipe runs and walks the boundaries of the plot, paying attention to the garden, the driveway and the area around the pool and tanks. Where a suspected line is located, a targeted check is carried out to narrow the search, so that floors and walls are opened only where the evidence points. Rooftop and ground-level tanks are inspected as part of the same visit. If the tank interior is worn, the cost of internal coating is typically SAR 25–70 per m², and the technician will explain what applies to your tank before any work begins.

To make the visit efficient, gather the water bills for the last few months and note when you first noticed a problem. Clear access to the meter, the main shut-off valve, the rooftop or ground tanks, and the garden taps will save time. Let the technician know which rooms have damp or stains, and whether any pumps or irrigation timers run automatically. Keep children and pets away from excavated areas, and make sure someone who knows the layout of the villa is available to answer questions during the inspection.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

Signs worth paying attention to

The following signs are worth checking before they grow:

• A water bill higher than usual with no change in use
• The meter keeps turning with every tap closed
• A hissing or trickling sound in the wall after the taps are off

The most common causes

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

How we choose the tool in Al Mlqa

How the work is done, step by step

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.
