Al Jwhra sits at about 21.4370, 39.2535, roughly 14.5 km from the centre of Jeddah, with an approximate radius of 1.2 km. Its centre lies about 31 m above sea level and around 7.1 km from the coast. Those facts shape how a hidden leak is approached here. Because the neighbourhood is a compact area set some distance inland, the first questions are about the building itself: how water reaches the property, where the storage tank sits, and whether any pipe runs underground or behind finished walls. Start with the water route from the supply connection through to the tank and the taps, and note any section where the pipe is buried or concealed.

What is left to the site visit is the actual detection. A technician will confirm which section is losing water, whether the cause is a joint, a fitting or a crack, and how far the damage extends before anything is opened. Reading the meter over a quiet period, checking floor and wall dampness, and listening for flow in concealed runs all belong on the day, not on a phone call. Any quote for repair should wait until that inspection is complete, since the scope depends on what is found. If the tank is part of the problem, the coating condition will be assessed in person. Tank internal coating is priced at SAR 25–65 per m², so the measured surface area matters before any figure is discussed.

To help the technician, have ready a few details: the date you first noticed higher bills or wet patches, the rooms or walls where dampness appears, whether the tank was cleaned or recoated before, and the location of the main isolation valve. Note whether water pressure has dropped and whether taps run when the supply is off. Clear access to the roof, the tank room and any ground-level meter is also useful. With this information, the visit can move straight to testing and the right fix can be agreed with you.

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?

These are the signs most often linked to hidden water leak detection:

• 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
• A water bill higher than usual with no change in use

Causes we see in the field

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

How we choose the tool in Al Jwhra

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.
