Bathroom waterproofing work in Jazan starts with the location itself. The centre of Jazan sits about 7 m above sea level (SRTM open elevation data), and the city is about 1.9 km from the sea coast (OpenStreetMap). Because of this, a technician first checks how moisture from the coast and the ground may reach a bathroom floor and walls, and whether the surface beneath the tiles is sound enough to hold a membrane. The first checks therefore cover the existing surface, any cracks, and signs of water already coming through the walls or floor. Published rates for this work are given per square metre, so the size of the bathroom is measured early and recorded for the quote, with bathroom waterproofing listed at SAR 15–40 per m².

Some matters can only be settled on the site visit. The technician needs to see the actual condition of the screed, the drain, the junction between floor and wall, and any old coating that must be removed. Cracks are priced per metre, from SAR 40–120 per m, so their length and position are measured in person. The choice between spray foam at SAR 20–45 per m², epoxy coating at SAR 35–90 per m², or a bitumen membrane at SAR 15–35 per m² depends on what is found there and on the household's wishes. Whether a separate basement or tank job is involved is also confirmed on the day, since basement waterproofing is SAR 50–150 per m² and tank internal coating is SAR 25–60 per m².

Information that helps the technician is worth preparing before the visit. Note the bathroom's dimensions, any areas where water has been seen, and when the problem first appeared. Mention whether the bathroom sits above another living space, since that affects the method chosen. Where a bathroom is on a roof or in a space with insulation, XPS boards at SAR 12–30 per m² or liquid roof waterproofing at SAR 8–25 per m² may be discussed. Keep access to the room clear so the surface can be inspected properly, and say whether the work must be done around daily use of the space.
