Can a hidden water leak in a residential building in Am Al Jwd be found without tearing up walls and floors? Many property owners ask this first, and the answer depends on the building's location and layout. Am Al Jwd is centred at 21.4158, 39.7176, about 14.8 km from the centre of Makkah, with an approximate radius of 4.1 km. The centre sits about 310 m above sea level, and the nearest wadi channel is about 1.3 km away. Knowing this helps the inspector consider how water moves through the ground and the building's water tanks and pipes.

The inspection follows a set order. First, the technician reviews the water supply route, from the main connection through storage tanks to the fixtures, and notes where pressure drops or meter readings look unusual. Next, the technician checks the rooftop and ground-level tanks, including their internal condition. Where a tank shows wear, the internal coating is priced at SAR 25–65 per m², so the scope of any repair is measured before work begins. Finally, the technician tests the pipework and suspect areas, using listening and pressure methods to narrow down the location of the leak before any opening up is considered.

Before the visit, gather the building's plans or any sketches of pipe routes, along with the dates of recent repairs and any past water bills that show unusual rises. Clear access to the tanks, the meter, the shut-off valves and the rooms where damp or staining has been noticed. Note when the problem first appeared and whether it is worse after the pumps run or at certain times of day. This information helps the technician plan the inspection and reduces the time spent on site.

For a whole building, a survey of the shared systems comes before unit-by-unit work.

Signs worth paying attention to

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

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

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

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