How do you know if a pipe is leaking inside your walls when nothing shows on the surface? In Al Fdl, a neighbourhood centred on 21.4364, 39.3237 and lying roughly 19.6 km from the centre of Jeddah, hidden leaks are a common concern for owners of residential buildings. The area has an approximate radius of 1.2 km and sits about 130 m above sea level, roughly 14 km from the sea coast. The nearest wadi channel runs about 2.5 km from the centre, which matters for how water moves and where damp can appear. Hidden leaks often show up first as a rising water bill, a damp patch on a wall, or a soft spot in a floor, long before any visible puddle forms.

Our inspection for hidden water leaks in residential buildings in Al Fdl starts with a short conversation about where you have noticed changes, such as meter readings, stains, or unusual sounds from the pipes. The technician then checks the water supply lines and the drainage system, and where the building has water storage, the tank is inspected too. Tanks are often part of the picture; if the internal coating has failed, the cost of recoating is typically in the range of SAR 25–65 per m², so the inspector will measure the surface and note its condition before you decide on any work. The inspection then moves through the building in a set order, testing sections one at a time so the findings can be traced to a specific pipe run or fitting.

To make the visit as productive as possible, gather your recent water bills and note the dates when you first saw damp, stains, or drops in water pressure. Clear access to the areas you want checked, including utility rooms, shafts, and the tank location, will save time. If you have plans or drawings of the building's plumbing, keep them ready, and tell the technician whether the building has a rooftop or ground-level tank. Finally, let the household know the inspection may involve some noise and temporary water interruptions, so that daily routines can be planned around the work.

For a residential building, shared risers, tanks and pumps are checked as one system.

Signs that call for hidden water leak detection

If you notice one of these signs in Al Fdl, 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
• A hissing or trickling sound in the wall after the taps are off

Where the problem usually comes from

• 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.
