Before booking a hidden water leak check in Al Sfarat, Riyadh, it helps to know a few facts about the area itself. The centre of Al Sfarat sits at 24.6806, 46.6240, about 6.4 km from the centre of Riyadh, with an approximate radius of 1.2 km. The centre of the district sits about 656 m above sea level, according to SRTM open elevation data. The nearest wadi channel is about 1.2 km from the centre of Al Sfarat, as mapped on OpenStreetMap. Because the wadi lies so close, the technician will want to know how the ground drains around your property before any test starts. Ask whether your building has been affected by runoff after rain, and mention any damp patches near the lower walls or garden edges.

What is left to the site visit is the part that cannot be judged from a map or a description. The technician will walk the property, listen for water flow in the walls and under floors, check pipe runs, and look at the water meter and pressure. Only on site can they confirm where a leak is, how far it has spread, and whether the cause is a supply line, a drain, or a tank. If a tank is involved, the technician may also assess the internal coating condition. Tank internal coating is quoted at SAR 25–70 per m², so the size of the tank surface will shape any later estimate. The final figure depends on what the visit finds, so do not treat the coating range as a fixed price for your job.

To help the technician, prepare a short summary before the visit. Note when you first noticed water loss, whether your water bills have risen, and which rooms or outdoor areas show signs of moisture. Share the age of the building and any previous plumbing repairs. Clear access to the meter, tank, and any inspection points will save time. Keep a record of any recent rain or flooding near the wadi, since that timing can point to where water is entering or leaving the system. Good notes make the visit faster and the findings clearer.

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

When do you need hidden water leak detection?

These are the signs most often linked to hidden water leak detection:

• The meter keeps turning with every tap closed
• A water bill higher than usual with no change in use
• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off

Causes we see in the field

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

How we choose the tool in Al Sfarat

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.
