Al Htym sits at 21.4948, 40.0161, roughly 20.2 km from the centre of Makkah, with an approximate radius of 1.2 km. That places it on the edge of the city rather than in its dense core, and the practical effect for duplex owners is that a leak survey here often has to account for longer supply runs, older service connections and plots that were built in phases. Our technicians plan each visit around the actual layout of the building, starting from the rooftop tank and working down through the risers, rather than assuming every duplex is wired the same way.

The centre of Al Htym is about 427 m above sea level, and the nearest wadi channel lies about 0.9 km away. Elevation matters because water pressure in the supply lines and the gravity-fed head above the tank both shape where leaks appear, so we check pressure behaviour at several points before opening walls. The nearby wadi is a reminder that ground conditions can shift after heavy rain, which can stress buried pipes and lift slabs, so we pay attention to damp patches in lower floors and at the junctions where pipes leave the ground. For tanks, coating work is priced at SAR 25–65 per m², and the size of the internal surface is measured on site so you receive a figure based on your own tank rather than an average.

Owners in this area often make the same few mistakes, and our service is designed to avoid them. Many wait for a visible stain before calling, by which point water has already soaked into plaster and insulation. Others assume a rising water bill must come from a single fault and overlook a slow drip behind a bathroom wall or a float valve that never shuts fully. Some also refill a tank and top it up repeatedly without checking the overflow pipe, or agree to a surface coating without first confirming the tank is sound. We begin with a checked diagnosis, so repairs are targeted and the money you spend goes to the actual source of the problem.

In a duplex, the two floors often share lines, so tests are done floor by floor.

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

Where the problem usually comes from

• A common cause: a corroded joint inside a wall.
• 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 Htym

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.
