Before we start: what we know about Alnuayriyah

Team note on Alnuayriyah: 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 Alnuayriyah sits about 49 m above sea level (SRTM open elevation data).

Pre-construction treatment for duplexes is most often needed to stop termites before they reach the structure, since soil treatment is far cheaper and more effective when done before the slab and walls go up. Builders who skip this step often end up treating a finished building, where access to the soil beneath is limited and the work is more disruptive for the household.

Alnuayriyah sits about 49 m above sea level, and this matters for the approach. Because the centre of the area is not at a low point where water tends to collect, the treatment plan should focus on the soil around the foundation and the trench lines rather than on standing-water concerns. The site should be checked for how the ground drains after rain, and the treatment zone should cover the full footprint of both units, including any shared walls and service trenches where insects can travel unnoticed. Termite treatment is usually priced at SAR 10–25 per m², so the total area of both units, plus a margin around the perimeter, is the main figure to confirm before work begins.

Before booking the visit, ask the service provider to measure the exact treatment area and state the rate per square metre in writing. Ask whether bird control or rodent control is also needed, since bird control is priced at SAR 30–80 per m and rodent control at SAR 200–500 per visit, and these are separate from soil treatment. Confirm whether a pest-control visit is included at SAR 150–400 per visit and what a follow-up visit costs at SAR 100–250 per visit. Finally, ask about an annual pest-control contract at SAR 500–1,500 per month, so you know the long-term cost of keeping the duplex protected after handover.

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