Team note on Alqunfudhah: 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..

Alqunfudhah is a coastal town, and its centre sits about 7 m above sea level while the sea coast lies roughly 0.4 km away. Because of that closeness to the water, the first things checked before buying or accepting a bathroom are the signs of moisture that a salt-influenced environment tends to bring: staining or bubbling on lower wall sections, a musty smell near the floor drain, and any patches where tiles sound hollow when tapped. Check the shower tray, the junction between floor and wall, and the area around the toilet base, since these are where water usually escapes first. A bathroom that looks dry on a sunny day can still hide a membrane that has failed underneath, so the visible surface is only the starting point.

Several points can only be judged at the site visit. The technician should inspect the actual slope of the floor toward the drain, test the condition of existing sealant and grout, look for cracks that are wider than a hairline, and confirm whether the shower area has a proper upstand. Pricing for bathroom waterproofing in this area typically falls between SAR 15 and SAR 40 per m², but the final figure depends on the room's measured area, the surface type, and whether old material must be removed first. Where cracks need repair, crack injection is priced at SAR 40–120 per metre, so the number of cracks found on the day will shape the quote. Ask for the method, not only the total, so you can compare what each option actually covers.

To help the technician arrive prepared, share the room's dimensions, the floor and wall finishes, how old the tiling is, and any history of leaks or damp in the rooms below or next to the bathroom. Mention whether the bathroom is on an upper floor, since that affects access to the drain and the walls. Photographs of problem areas taken in good light are useful, as are notes on when the damp appears, whether after showering, heavy rain or humid weather. Clear information at the start lets the visit focus on the questions that matter, and it makes it easier to choose a method that suits the room you actually have.

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