Is a damp patch on a bathroom wall in a Ghrnata duplex a sign of a hidden leak? Often it is, and the sooner it is traced, the less damage it causes. Ghrnata sits about 11 km from the centre of Riyadh, with an approximate radius of 2.8 km, and it is mainly villas. Many of the homes here are duplexes that share plumbing runs, so water from an upper bathroom can travel down into a lower unit before anyone sees a stain. The centre of Ghrnata sits about 617 m above sea level, but altitude does nothing to stop a slow leak from soaking into walls and floors, which is why a proper check is worth arranging rather than waiting for the damage to show.

The inspection starts with a conversation about where you have noticed moisture, peeling paint, a soft floor tile, or a rise in the water meter reading. The technician then checks the bathroom and the areas directly beneath it, looking at the drains, the supply pipes, the seals around the shower tray and toilet, and the walls that back onto the neighbouring unit. Where a leak is suspected inside a concrete or tiled structure, the inspection is designed to narrow the search before any opening up is done, so that only the section that needs attention is disturbed. If a water tank is part of the问题, the tank's internal condition is assessed separately, and internal coating is priced at SAR 25–65 per m², depending on the work required. Each step is explained as it happens so you understand what has been found.

To make the visit as productive as possible, clear the bathroom and the area under it so the technician can reach the walls and floor edges. Note when you first noticed the problem, whether it is worse after showers or at certain times of day, and gather any previous plumbing or repair records for the property. If you share a wall or pipe run with a neighbour, let them know beforehand, since the cause may lie in their unit and access will help the check go faster. Keep a copy of your water meter readings for the past few months if you have them, as a sudden rise can point towards a leak that is hard to see. Having this information ready means the visit can focus on finding the source quickly, and any repair recommendation will be based on what the inspection actually shows.

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

How the work is done, step by step

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.
