Hidden water leaks in residential buildings in Al Awaly are best approached by first considering the local setting. The centre of Al Awaly sits at 21.3398, 39.9045, about 7.3 km from the centre of Makkah, with an approximate radius of 5.6 km. At around 311 m above sea level, the area's ground conditions and drainage patterns differ from lower-lying districts. The nearest wadi channel is about 2.4 km from the centre of Al Awaly, so seasonal runoff and groundwater movement are worth keeping in mind when a building shows signs of moisture. Starting with the location and the building's position relative to slopes and drainage gives the technician useful context before any equipment is switched on.

Some matters can only be settled on site. The technician will walk the property, check walls, floors and ceilings for damp patches, staining or softened plaster, and listen for pipe noise where the building is quiet. Access to shafts, ducts and ground-floor slabs, as well as the condition of any water storage tank, will be assessed in person. If a tank needs a new internal coating, its cost is quoted per square metre at SAR 25–65 per m², but the final figure depends on the measured surface area and the coating system chosen, so it is confirmed only after inspection. Decisions about pressure testing, opening walls or lifting tiles are also made on the day, once the leak's likely route is clearer.

To help the technician work efficiently, residents should have ready the building's plans if available, the location of the water meter and main shut-off valve, and a record of when damp or unusual water bills first appeared. Note any rooms that feel cold or smell musty, and any areas where the water pressure seems to drop. Keep pets and children away from exposed areas, and clear access to cupboards, utility rooms and the roof or tank area. Providing this information in advance lets the visit focus on finding the leak rather than gathering background details.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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

Where the problem usually comes from

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

Tools and methods, and when we use them

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.

Common mistakes we see

• Breaking tiles at random before the line is identified
