Wall damp in schools in Khamis Mushait most often shows up as rising damp at the base of classroom and corridor walls, along with staining and peeling paint where rainwater runs down external walls and collects around the foundation. Because school buildings have long walls, large open halls and many people coming and going, moisture can build up quietly between terms and only become obvious when plaster starts to flake or a musty smell develops in storerooms and lower-floor rooms.
Khamis Mushait sits at high altitude, with the centre about 1998 m above sea level, so the climate and building conditions differ from coastal cities. Cooler nights can cause condensation on cold internal walls, while heavy rain episodes can soak exterior render quickly. This means the treatment approach should focus on finding the true moisture source before choosing a product. Crack injection is priced at SAR 40–115 per metre, and it is often needed where structural cracks let water track through a wall. For ground-contact walls, basement waterproofing is priced at SAR 50–145 per m², while epoxy coating at SAR 35–85 per m² may suit interior walls and tanks. Where a school has a rooftop plant room or flat roofs, liquid roof waterproofing at SAR 10–25 per m² is a common option.
Before the visit, ask the provider to confirm which wall areas they will inspect, including external ground-level walls, any basement or storeroom, and internal walls next to bathrooms. Ask how they will identify the moisture source, whether they will check drainage and downpipes, and how they will protect classrooms and pupils during works. Request a written breakdown showing the method and the unit rate for each area, so the scope can be compared against the price ranges above. Finally, ask whether the school's maintenance team can be given access times that avoid teaching hours.
For schools, the larger jobs are planned for weekends and holidays.
