Before buying or renovating a home in Al Aryja, Riyadh, one of the most common problems we see is a hidden leak behind bathroom walls, under tiles, or beneath the floor screed. Water rarely announces itself at first. It shows up as damp patches on a neighbouring wall, a musty smell, peeling paint near the shower, or a water bill that creeps upward for no clear reason. Because the damage often sits inside the structure, a visual check alone is rarely enough, and a buyer can inherit a repair bill that was never visible during a quick viewing.

Local conditions shape how we approach the job. Al Aryja sits at about 629 m above sea level, roughly 10 km from the centre of Riyadh, and its centre lies at 24.6257, 46.6566, with an approximate radius of 2 km. The nearest wadi channel runs about 0.3 km from the centre, which matters during heavy rain, when ground moisture and drainage pressure can push water toward low foundations and ground-level bathrooms. Our checks therefore look at the seams where walls meet floors, the drainage points, and any sign that moisture is tracking in from outside rather than from the pipes alone. For households with water storage, we also consider the rooftop or ground tank: tank internal coating is typically SAR 25–70 per m², so a tank that is leaking or corroding is worth pricing into your decision alongside the bathroom work.

Before the visit, ask the provider a few direct questions. Ask whether they test pressure in the supply lines and run dye or moisture-meter checks, and whether they can explain what they found in plain terms. Ask how they will access the area without unnecessary breaking-out, and whether they will confirm the repair scope in writing before any work starts. If you are buying, share the property address and the age of the plumbing so the inspector knows what to expect. Clear answers at this stage usually mean fewer surprises once the walls are opened.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Tools and methods, and when we use them

From the first visit to the report

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.
