Before we start: what we know about Abha
Team note on Abha: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Abha sits about 2230 m above sea level (SRTM open elevation data).
Abha sits in the southwestern highlands, where cool, humid nights and wet seasons mean that moisture can appear on bathroom walls even when nothing is leaking. Because of this, the first question for a residential bathroom is whether the water is coming from inside the wall or simply from the air. Before any work starts, the team checks the wall behind the tiles, the junction with the floor, and the drainage points, since these are the places where water most often enters a building. Waterproofing only makes sense once the source is confirmed, so the inspection comes first.
For a bathroom in an apartment or villa, this affects the scope of work directly. If the leak is traced to a cracked seal or a failed membrane, the repair is limited to that area and the floor or balcony layer above it. If the moisture is damaging a wall shared with a basement, the cost per square meter of basement wall treatment, which runs from 50 to 145 riyals per m², becomes relevant. Any sign of structural damage, such as swelling plaster or cracked joints, is recorded before choosing a method.
Before the visit, it helps to note when the stains appear, whether they worsen after rain or showers, and which rooms sit directly above or below the bathroom. Keep a few photos of the affected walls and any old invoices for previous repairs. Ask the team how they will confirm the leak location, what protective coating they recommend after floor insulation (which ranges from 15 to 40 riyals per m²), and whether the wall-protection layer, priced from 10 to 30 riyals per m², fits the bathroom you have.
For a residential building, shared risers, tanks and pumps are checked as one system.

Questions from Abha
What happens after the leak location is found?
The service provider gives you a report showing the leak's location and cause, along with a recommended repair method. You can request the repair from the same provider or ask for other offers through the platform.
How can I tell if the leak is inside the wall and not caused by humidity in Abha?
Humidity usually shows up spread out and fades with ventilation, while a leak concentrates in one spot and gets worse over time. Testing with moisture meters and thermal imaging can settle the difference.
Can a bathroom leak cause structural damage?
Yes. Ongoing leaks allow water to reach concrete and steel, causing rust that weakens the structure. Persistent moisture also promotes harmful mold growth. We recommend inspection at the first sign of a leak.
