Before we start: what we know about Aljumum

Picture a homeowner in Aljumum who has noticed a damp patch spreading across the bathroom wall behind the shower, with tiles that have started to lift near the floor. Like many owners of older family homes here, they want the problem fixed properly once rather than patched every year, but they are unsure what the work should cost and whether the quotes they receive are reasonable. Their main concerns are how far the leak has travelled, whether the floor and walls need separate treatment, and how to compare offers without being misled by vague figures.
Aljumum sits about 200 m above sea level, which means the area is not a low-lying flood zone, so standing water is less often the cause of dampness than poor detailing around the shower tray, drain and wall junctions. For a bathroom, published rates for bathroom waterproofing run from SAR 15 to SAR 40 per m², while epoxy coating runs from SAR 35 to SAR 90 per m² and spray foam from SAR 20 to SAR 45 per m². A cracked joint or hairline gap may instead be priced per metre, at SAR 40 to SAR 120 per m, so the owner should ask whether the quote separates area work from crack injection. Higher rates for epoxy generally reflect a harder-wearing finish rather than a better result in every case.
The practical sequence starts with a site inspection that records where the damp appears and whether it is rising from the floor or tracking down from above. Next, ask each contractor to measure the bathroom floor and wall areas separately and to list any crack lengths, so every offer covers the same scope. Compare the quotes line by line against the published ranges above, and check that each includes surface preparation, drainage detailing and a written warranty period. Finally, arrange a flood test or a dry-period check before tiling is refitted, and keep the measurements and invoices together for future reference.
