The most common problem we see in apartments with hidden water leaks is water that never reaches the surface. Pipes run inside walls, under floor screeds and behind tiled bathrooms, so a leak can soak plaster or wood for weeks before any stain appears. In Al Dhw, residents often first notice a damp patch on a ceiling below a bathroom, a musty smell in a corridor, or a water meter that keeps turning when every tap is closed. Those signs point to a leak that a visual check will miss.

Al Dhw sits at roughly 587 metres above sea level, with its centre at 24.6297, 46.7143, about 10.1 km from the centre of Riyadh and within an approximate radius of 1.2 km. The nearest wadi channel is about 2.8 km from the centre, so rainwater can run through the area during heavy storms. That matters for leak detection: a ground-level apartment may have moisture from outside seeping into walls, which can look like a plumbing leak. A good inspection separates internal supply and drainage faults from external water entry before any wall is opened, so repairs are aimed at the right source. Where a water tank is part of the system, tank internal coating is priced at SAR 25–70 per m², which is useful to know if the inspection shows the tank itself is contributing to the problem.

Before the visit, ask the technician how they will locate the leak without unnecessary demolition, and whether they will test each section of the supply and drainage lines separately. Ask whether the price covers the detection only or also the repair, and what happens if the source is outside the flat, such as in a shared riser. Confirm which rooms and floors will be checked, and ask for a written note of the findings with photos of any moisture readings. Finally, agree on how access to neighbouring units will be arranged, since leaks in apartments often travel through shared walls and ceilings.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

Signs worth paying attention to

If you notice one of these signs in Al Dhw, it is a good moment to talk to the team:

• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off

• A common cause: a corroded joint inside a wall.
• A cracked pipe under floor tiles.

Tools we use in Al Dhw

The steps in order

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.
