Before we start: what we know about Al Nhda

The centre of Al Nhda is at 21.6185, 39.1284, about 9.5 km from the centre of Jeddah, with an approximate radius of 2 km. The approximate area shown on the map is centred here. Al Nhda is about 2.3 km from the sea coast (OpenStreetMap).

The centre of Al Nhda sits about 7 m above sea level (SRTM open elevation data). Main roads in or near Al Nhda: Prince Sultan Road, King Abdulaziz Road, Hira Street.

Al Nhda sits about 9.5 km from the centre of Jeddah, with an approximate radius of 2 km, so most of the neighbourhood is a compact, self-contained district rather than a stretch of the busy old city. Its centre lies at 21.6185, 39.1284, and the area is only about 7 m above sea level. Those facts shape how we approach hidden leaks here. Hotels and serviced apartments in a low-lying district can see water pressure and drainage behave differently from higher ground, so our technicians begin each survey by mapping how water enters and leaves the building before any detection equipment is switched on.

The location also has a direct effect on the work. Al Nhda is about 2.3 km from the sea coast, which means the air is humid and salt can be present in the wider environment. Damp conditions can hide the early signs of a leak in walls, floors and ceilings, so we pay close attention to skirting boards, ground-floor corners and areas behind wet rooms. Because the district is compact, our teams can reach a property quickly after a report, which helps limit the spread of moisture into finishes and reduces the time a guest or tenant is disturbed.

Owners of hotels and serviced apartments often make the same few mistakes, and our work is designed to avoid them. The first is waiting for a visible stain before calling anyone, when by then the water has usually travelled well beyond its source. The second is treating each damp patch as a separate problem instead of checking the whole water system together. The third is ignoring the tank, since storage tanks can leak through their internal walls; where a coating repair is needed, the internal coating cost of SAR 25–65 per m² is a useful starting point for planning a budget. We also avoid patching the surface alone, because a hidden leak left in place will return.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

When do you need hidden water leak detection?

If you notice one of these signs in Al Nhda, 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 cracked pipe under floor tiles — we check this before anything else.
• A common cause: a hot line that expands and contracts with use.

Tools and methods, and when we use them

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.

What we advise against

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

What you receive

The written output: a technical report with the readings, the likely leak position and a confidence level. The report is numbered and can be checked with its verification code.
