Bathroom leaks are the most common problem we see in homes and small apartment blocks in Al Aard, Riyadh, and they are rarely obvious at first. Typical signs include a damp patch on a ceiling below a bathroom, a soft or discoloured skirting board, a sudden rise in the water meter reading, or a musty smell that comes and goes. If you notice any of these, it is time to call, especially if the wall behind a shower or the floor around a toilet feels cold or wet to the touch. Waiting usually makes the repair larger, because water travels along pipes and under tiles before it shows on the surface.

Al Aard sits at roughly 671 metres above sea level, about 21.2 km from the centre of Riyadh, and its centre lies only about 1 km from a wadi channel. Those local facts shape how a technician approaches the job. Ground near a wadi can hold moisture differently from the flat terrain elsewhere in the city, so a leak may seem to come from one wall but actually track through the slab from a supply line below. Technicians working in Al Aard therefore tend to check the water supply, the drainage lines and the storage tank together, rather than assuming the first damp spot is the source. Where a rooftop or ground tank is involved, internal coating work is usually priced per square metre, at SAR 25–65 per m², which is worth knowing when comparing options.

Before the visit, ask the provider a few clear questions. Confirm whether they will test the bathroom with pressure and moisture readings rather than only looking at the surface, and ask how they will check the area around the wadi-side wall if your home is close to it. Ask what the inspection includes, whether a written note of findings will be provided, and how any tank or shaft work would be quoted. Ask who will attend and whether they can explain the cause in plain terms before any work starts. A reliable visit should leave you with a clear diagnosis and a clear next step.

Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.

Tools and methods, and when we use them

The steps in order

1. Pipe or waterproofing?: We separate a pressurised pipe leak from water passing through the floor layer.
2. Listening and moisture readings: Readings are taken around the shower, basin and toilet lines.
3. Floor test: A controlled water test on the floor shows whether the layer lets water through.
4. Recommendation: You know which repair is needed before any tile is lifted.
