Before we start: what we know about Al Hlqa

The centre of Al Hlqa is at 21.3482, 40.4548, about 9.6 km from the centre of Taif, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. The nearest wadi channel is about 2.3 km from the centre of Al Hlqa (OpenStreetMap).

The centre of Al Hlqa sits about 1575 m above sea level (SRTM open elevation data). Main roads in or near Al Hlqa: Airport Road, Sulaiman Al Rajhi Road.

An owner of a flat in an apartment block who notices a damp patch on a ceiling, a faint musty smell in a corner, or a water bill that has crept up without any obvious reason is facing a problem that often hides behind plaster and tiles. Water that escapes from a pipe inside a wall or under a floor rarely announces itself, and by the time stains appear the damage may already be spreading. For an owner who lives away, rents out the unit, or only visits seasonally, the leak can run for weeks before anyone is aware of it.

The local setting matters for how you approach this. Al Hlqa sits at about 1575 metres above sea level, roughly 9.6 km from the centre of Taif, and its centre lies at 21.3482, 40.4548. The nearest wadi channel is about 2.3 km away, so when heavy rain falls, water can move quickly through the surrounding ground and seep into building foundations and lower walls. A leak combined with groundwater movement can make moisture harder to trace, so it is wise not to assume the source is always the most visible one. Owners in the area should also consider the rooftop water tank, since its internal coating, typically priced at SAR 25–55 per m², can deteriorate and allow slow losses that are easy to miss.

Start by checking your water meter when no tap or appliance is in use, and note the reading. Repeat the check after a set interval; a steady rise points to a leak somewhere in the supply. Next, inspect the bathroom and kitchen under-sink areas, the base of toilets, and the area around the water heater for drips or softened walls. Then look at the rooftop tank and its fittings, and check ceilings directly beneath it. If the readings and visible checks do not settle the question, arrange a professional inspection that uses listening and pressure equipment to pinpoint the source before any wall or floor is opened.

In apartment buildings, the floor below is often where a leak shows first.

Signs worth paying attention to

If you notice one of these signs in Al Hlqa, it is a good moment to talk to the team:

• 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 corroded joint inside a wall.
• A common cause: a cracked pipe under floor tiles.
• A common cause: a hot line that expands and contracts with use.

Tools we use in Al Hlqa

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.
