Is there a hidden water leak in my home in Al Qadsya, and how do I know before I buy? For a property owner in this neighbourhood, that question matters before any purchase, because a leak behind a wall or under a floor rarely shows on the surface. Al Qadsya is centred at 24.8182, 46.8278, roughly 19.3 km from the centre of Riyadh, and it covers an approximate radius of 1.2 km. The centre of the district sits about 579 m above sea level, and the nearest wadi channel lies about 0 km from that centre, so the ground and drainage here are worth considering when you assess any building.

A buyer's inspection should follow a clear sequence. Start by reading the water meter over a quiet period and noting the reading, then check it again after a few hours with no taps or appliances running; any movement points to a possible leak. Next, examine the rooftop and any water tanks, since tank internal coating is priced at SAR 25–70 per m², and a tank that has lost its coating can leak quietly for a long time. Walk the property listening for hissing or running water, look for damp patches, staining, soft or discoloured plaster, and musty smells, and check under sinks, around toilets, and along exposed pipe runs. A detection visit should combine these checks with equipment suited to hidden pipes, so that the findings can be tied to a specific location rather than guessed at.

Before the visit, gather the documents and information that help the inspector work efficiently. Have the water meter location ready and any recent bills to compare consumption, and note any past repairs, renovations, or areas where you have seen damp or stains. Clear access to the tank, roof, shafts, and the spaces behind kitchen and bathroom fittings, and tell the inspector about any running water sounds or pressure changes you have noticed. Ask for a written summary of what was found, where, and what it would involve to fix, so you can make the purchase decision with clear facts in hand.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

How we choose the tool in Al Qadsya

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.
