Al Hzm sits at 24.5473, 46.6536, roughly 18.6 km from the centre of Riyadh, with an approximate radius of 1.2 km. That distance matters for scheduling: a technician travelling from the city centre must plan the visit around a fuller day, and a leak survey booked for Al Hzm should allow for the drive rather than being squeezed between jobs closer in. Because the area covers a compact radius, most homes here can be reached within one route, which helps keep the survey focused on the property rather than on travel.

The centre of Al Hzm sits about 676 m above sea level, according to SRTM open elevation data. Elevation shapes how water moves through a building. Pressure in the supply lines and the way water settles in storage tanks both depend on height, so a hidden leak is often found by checking pressure readings and tank levels as well as the walls and floors. The nearest wadi channel is about 0.8 km from the centre of Al Hzm, according to OpenStreetMap. Seasonal runoff from a nearby channel can saturate the ground around a property, which can hide a slow leak in a buried pipe or make damp patches look like condensation. Our detection work here therefore includes checking soil moisture and drainage paths, not only the inside of the home.

Owners in Al Hzm often make the same few mistakes, and avoiding them saves time and cost. Many wait for a visible stain before calling anyone, when a leak has usually been running for weeks. Others assume a rising water bill is a tariff change and ignore it, or they break open walls on a guess without first pinpointing the source. Some also neglect the tank: tank internal coating is priced at SAR 25–70 per m², so a worn lining that lets water seep should be assessed and quoted before any repair. Testing first, then opening only where the evidence points, keeps the damage to a minimum.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for hidden water leak detection

The following signs are worth checking before they grow:

• A water bill higher than usual with no change in use
• The meter keeps turning with every tap closed
• A hissing or trickling sound in the wall after the taps are off

The most common causes

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

Tools we use in Al Hzm

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.
