Picture a family who has lived in an apartment in Al Slam for several years. One morning the water bill arrives higher than usual, yet nothing in the flat looks wrong. There are no puddles, no stains on the ceiling, and no dripping taps. Over the following weeks the damp smell in a bathroom wall grows stronger, and the owner begins to wonder whether a pipe behind the tiles is leaking quietly. Many owners in this situation wait too long, because hidden leaks rarely announce themselves until the damage is already spreading.

Al Slam sits at the centre point 21.4633, 39.9558, roughly 13.1 km from the centre of Makkah, within an approximate radius of 1.2 km. The area stands about 388 m above sea level. For residents, this means that the building's water system is often managed at a distance from the main city grid, and pressure and storage arrangements can differ from older central districts. Water is frequently stored in rooftop or ground tanks, so a leak in the tank or its connecting lines can go unnoticed for a long time. Owners should also remember that tank internal coating is priced per square metre, typically in the range of SAR 25–65 per m², so a clear assessment of the tank's condition before any repair helps keep costs predictable.

If you suspect a hidden leak in your apartment, act in a clear order. First, read your water meter at a time when no water is being used, then read it again two hours later; any change points to a leak somewhere in the system. Second, check the tank and its overflow pipe for signs of seepage, rust, or constant refilling. Third, note any damp patches, soft plaster, or unusual smells and mark where they appear. Fourth, arrange a non-invasive inspection to locate the leak before any tiles are removed. Finally, once the source is found, agree on the repair scope in writing, including the area to be treated and the coating method, before work begins.

In apartment buildings, the floor below is often where a leak shows first.

Signs worth paying attention to

• 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 corroded joint inside a wall.

How we choose the tool in Al Slam

From the first visit to the report

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.
