Before any hidden water leak is looked at in Al Rwda, Jeddah, it helps to know where the district sits. The centre of Al Rwda is at 21.5659, 39.1573, about 3 km from the centre of Jeddah, with an approximate radius of 2.4 km. That location matters for a first check, because the district is set a short distance inland rather than on the shoreline. The centre sits about 12 m above sea level, and the coast is about 3.5 km away. A property owner or buyer can therefore start by confirming the plot's exact position and noting how the building drains, since a low-lying or slightly sloped site can change where moisture collects and how a leak travels through floors and walls.

What is left to the site visit is the part that cannot be judged from a map. A technician will walk the property, look at damp patches, staining, soft or discoloured plaster, and any change in pressure or meter readings, and will trace pipe runs in person. They will also inspect water tanks and their condition. If a tank needs refurbishing, the internal coating is priced at SAR 25–65 per m², and the actual figure depends on the tank's size and surface condition, which only a visit can establish. Decisions about opening walls, lifting tiles or testing specific lines should also wait until the visit, so that the least invasive method is used first.

To help the technician, gather information before the appointment. Note when damp or odd water sounds were first noticed, which rooms and floors are affected, and whether the bills have risen. Have the layout of the water supply and drainage to hand, along with any earlier repair records and the age of the building. Give the technician access to the roof, the tank area and any ground-level plant room. A clear account of the problem, the building's history and the exact address position, expressed as the coordinates 21.5659, 39.1573, will let the visit focus on the likely leak route rather than on general searching.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

When do you need hidden water leak detection?

The following signs are worth checking before they grow:

• A hissing or trickling sound in the wall after the taps are off
• A damp patch that slowly grows on a wall or ceiling
• A water bill higher than usual with no change in use
• The meter keeps turning with every tap closed

Causes we see in the field

• A common cause: a hot line that expands and contracts with use.
• A common cause: a cracked pipe under floor tiles.
• A corroded joint inside a wall.

Tools we use in Al Rwda

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.
