Picture a homeowner in a villa who notices the water bill creeping up for no clear reason, a damp patch on a bedroom wall, or a floor tile that feels cool in one spot. Nothing is visibly broken, yet something is draining water away out of sight. This is the typical situation where hidden leaks go unnoticed for weeks, and the owner is left guessing where to start. The goal is to find the leak with as little digging as possible and to fix the cause, not just the symptom.

Al Mhjr sits at about 21.4271, 39.2075, roughly 13.4 km from the centre of Jeddah, within an approximate radius of 4.1 km. Its centre lies about 11 m above sea level, and the area is about 2.4 km from the sea coast. For residents, this means that the district is a reasonable distance from the city core but still close enough to the coast that salty, humid air can affect buried metal pipes, fittings and tank surfaces over time. Water storage tanks here are worth checking regularly, since a tank's internal coating is a known factor in how long it protects the water inside. Tank internal coating is typically priced at SAR 25–65 per m², so a quote for coating work should be compared against the actual surface area being treated.

Start with the simplest checks. Read the water meter with every tap and appliance switched off, note the reading, and check it again after an hour. If it moves, water is escaping somewhere in the system. Next, inspect the tank and its connections for drips, staining or overflow. Then walk the property and look for damp skirting boards, bubbling paint, soft ground in the garden or unexplained wet patches. Record every location you find, because this map guides the investigation. If the meter moves but no leak is visible, arrange a hidden leak detection visit so the search can focus on the suspected run of pipe. Finally, once the leak is located, have the damaged section repaired, re-read the meter to confirm the loss has stopped, and keep a simple monthly log so any new problem is caught early.

Each job ends with a written report that carries a verification code you can check on our site.

Signs that call for hidden water leak detection

The following signs are worth checking before they grow:

• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off
• The meter keeps turning with every tap closed

Causes we see in the field

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

Tools we use in Al Mhjr

The steps in order

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.
