Picture a homeowner in a villa who notices that the water bill has crept up for no clear reason, and that a damp patch has appeared on a bathroom wall. There is no visible pipe burst and no pool of water on the floor. Hidden leaks like this are common in many homes, and the usual first instinct is to dig or break open tiles at random. A more measured approach starts with understanding the setting first.

Nmar sits at 24.5689, 46.6804, roughly 16.1 km from the centre of Riyadh, with an approximate radius of 1.2 km. Its centre lies about 629 m above sea level, and the nearest wadi channel is about 0.3 km away. For an owner, this matters because a property this close to a wadi can experience seasonal ground movement and rainwater runoff that may stress buried pipes and foundations. A leak that appears after heavy rain may be linked to surface water finding its way into fittings, so timing is worth recording. Owners should also remember that water storage tanks are a common source of loss, and internal tank coating is priced at SAR 25–70 per m², so inspecting the tank early can prevent larger repair work later.

Start by reading the water meter with every tap and appliance switched off, then check again after an hour; movement on the dial points to a leak in the supply line. Next, note when the damp or the bill increase began and whether it followed rainfall near the wadi. Inspect accessible tank walls and the roof tank for staining or flaking coating, and check outdoor taps and irrigation lines for soft ground. If the readings still point to a hidden fault, arrange a professional leak survey before any excavation, and ask for the findings in writing so the repair can be planned around the actual location of the leak.

Signs worth paying attention to

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

• 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

Causes we see in the field

• 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 we use in Nmar

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.
