Before we start: what we know about Aljumum

Team note on Aljumum: 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 Aljumum sits about 200 m above sea level (SRTM open elevation data).

Imagine the owner of a villa in Aljumum who has just moved in, or who has lived there for years and is starting to notice damp patches on a ground-floor wall, a warm and uneven top floor in summer, and a small crack along the basement wall after the last heavy rain. Like many owners of this property type, they want the problem fixed once, properly, without guessing which part of the house is causing it. They are not experts, so the first question is always the same: where should the money go first?

The local facts matter here. The centre of Aljumum sits about 200 m above sea level, which places the area on higher ground than the coastal districts. Higher ground can mean drainage runs quickly, but it also means the structure is exposed to different sun and wind loads, so roofs and external walls often take more heat and driving rain than owners expect. For a villa, this points to checking the roof and the lower walls together rather than treating each as a separate job. Typical indicative ranges for the main works are SAR 8–25 per m² for liquid roof waterproofing, SAR 15–35 per m² for a bitumen membrane, SAR 12–30 per m² for XPS boards, and SAR 20–45 per m² for spray foam, so the roof and insulation choice can be compared directly on cost per square metre.

A practical sequence helps. First, walk the property after rain and mark every damp stain, hairline crack and lifted tile. Second, look at the basement and ground-level walls: basement waterproofing is listed at SAR 50–150 per m², and cracks are typically priced at SAR 40–120 per metre, so ask for both to be quoted separately. Third, decide on the roof, comparing liquid waterproofing with a membrane. Fourth, if the villa has a water tank, add a tank internal coating at SAR 25–60 per m². Finally, ask each provider for a written breakdown per m² and per metre, the materials used, and the areas covered, so the owner can compare quotes on equal terms before any work begins.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
