Is water coming into your basement or foundation in Jazan, and does it need attention today? Jazan's centre sits about 7 m above sea level, and the city is roughly 1.9 km from the sea coast. Both facts matter when water appears below ground, because the low elevation and nearby coast mean moisture and groundwater can build up quickly around a building's lower walls and floor. When you see seepage, damp patches, or standing water in a basement or at the foundation, treat it as an urgent job rather than a cosmetic one, and arrange a visit without delay.

When the crew arrives, the first step is an inspection of where the water is entering. They will check the basement walls and floor, the joints, and any visible cracks, and they will look at the exposed foundation to understand how far the damage reaches. Crack injection is priced at SAR 40–120 per metre, so the inspector will measure the length of each crack that needs sealing. For the basement itself, waterproofing is quoted at SAR 50–150 per m², so the crew will measure the wet area to establish the scope. They will also note whether surfaces need coating, such as epoxy at SAR 35–90 per m², or a spray foam option at SAR 20–45 per m², so the right material can be recommended for the conditions they find.

Before the visit, clear the areas you can access so the crew can work on the walls and floor. Move stored items away from the damp zones, and remove any loose debris that might hide cracks. Gather any earlier paperwork about previous repairs or leaks, and note when the water first appeared and whether it rises after rain or during high tides. Be ready to show the exact locations of wet spots and to point out any bathrooms or tanks nearby, since bathroom waterproofing is quoted at SAR 15–40 per m² and tank internal coating at SAR 25–60 per m² and may be part of the same job. Having this information ready helps the team give you a clear and accurate assessment on the first visit.

If water is flowing, close the main valve first, then call or message with photos.
