Are hidden water leaks in an office or commercial building in Al Rwaby, Jeddah, worth checking for before they show up as damp walls or a higher water bill? Al Rwaby sits at roughly 21.4682, 39.2689, about 13 km from the centre of Jeddah, and the neighbourhood covers an approximate radius of 1.2 km. The centre of the district sits about 52 m above sea level, and it is about 9 km from the sea coast. For a company premises, that means a building here can rely on rooftop or ground-level storage tanks and pumping equipment, and the leaks that matter most are often out of sight inside pipe runs, tank walls and concrete slabs.

The inspection follows a set order. The technician first reviews the building layout, water supply routes and where tanks and pumps are located. Next comes a survey of the accessible areas to look for signs such as staining, soft plaster or unusual readings on the meter. Where a tank is involved, the team checks its internal condition, and the tank coating is priced at SAR 25–65 per m², so the scope of any coating work depends on the measured area. The visit ends with a summary of where water is escaping, what has been checked and which areas still need attention, so the property manager can decide on repairs.

Before the visit, gather the building plans or any drawings showing pipe routes, the location of the main water meter and the valves, and the dates of any previous repairs. Note recent changes in your water bills and any damp or discoloured areas on walls and ceilings, with photos if possible. Make sure staff can give the technician access to the roof, the plant room and the tank areas, and confirm who will be on site to answer questions. Clear any stored items around tanks and pumps so the inspection is not delayed.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs worth paying attention to

The following signs are worth checking before they grow:

• A damp patch that slowly grows on a wall or ceiling

Tools we use in Al Rwaby

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.
