Imagine an owner who has just bought a home in a quiet residential district and notices a damp patch on a wall, a slightly higher water bill than expected, or a faint smell near a bathroom. Before deciding on repairs or committing to a purchase, that owner wants to know whether water is escaping hidden inside walls, floors, or the storage tank on the roof. Many people in this situation delay, hoping the problem will go away, when a little early checking can save considerable trouble later.

Al Mrba sits around 24.6599, 46.7098, roughly 6.9 km from the centre of Riyadh, with an approximate radius of 1.2 km. Its centre lies about 595 m above sea level. For an owner, these facts mean the area is close enough to the city centre for practical access to plumbers and suppliers, yet the district is small and defined, so a local inspection visit can be planned efficiently. The elevation matters too: a property at this height may rely on rooftop storage and pumping, so the storage tank and its supply lines are worth examining as a possible source of concealed leakage.

Start by noting when the signs appear and where, such as damp plaster, peeling paint, or a meter that keeps moving when no tap is open. Next, check the water meter with all taps and appliances switched off, and recheck it after a short interval to confirm whether flow continues. Ask a qualified plumber to test the pipework and the rooftop tank, and to report on the condition of the internal coating, since recoating a tank is priced per square metre at SAR 25–70 per m², so measuring the surface first gives a clearer cost estimate. Finally, obtain the findings in writing before you buy or agree repairs, so the decision rests on evidence rather than assumption.

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

Signs that call for hidden water leak detection

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

• 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
• The meter keeps turning with every tap closed

The most common causes

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

Tools we use in Al Mrba

How the work is done, step by step

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.
