Is there a hidden water leak in my apartment, and how would anyone know without breaking open the walls? For property owners in Al Mrwa, Makkah, this is a common worry. The area's centre sits at 21.4318, 39.7091, about 16.1 km from the centre of Makkah, and its approximate radius is 1.2 km. The centre sits about 221 m above sea level, and the nearest wadi channel runs about 0.4 km from that centre. Because of this terrain and the local water arrangements, leaks in buried pipes and behind tiles can go unnoticed for a long time, so a structured check is worth arranging.

Our inspection begins with a review of the water readings and any signs you have noticed, such as damp patches, a drop in pressure, or unexplained rises in the bill. A technician then walks the property and tests the supply lines, drainage, and storage tanks. Where a tank is involved, the internal coating is assessed, and the cost for that work is typically SAR 25–65 per m², depending on the condition of the surface. Each step is recorded so you can see which areas were checked and what was found. Nothing is opened up without your agreement.

Before the visit, gather any previous plumbing invoices, the building's layout drawings if you have them, and a list of the rooms where you have noticed moisture or odours. Note when the problem first appeared and whether it is worse after the water is used or during the night. Clear access to the storage tank, the meter, and the bathrooms and kitchen will help the technician work efficiently. Having the water meter reading recorded on the day of the visit also gives a useful baseline for comparing results afterwards.

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

Tools we use in Al Mrwa

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.
