Floor and balcony leaks in duplexes usually start where the upper floor meets the lower one, and at balcony edges where water sits against a slab that was never sealed properly. In Alnuayriyah, the most common complaint is damp patches on the ceiling below a balcony or bathroom, often showing up after the first heavy rain of the season. Because these leaks travel through the structure before they appear, the visible stain is rarely the actual source.
The local setting changes how we approach the job. The centre of Alnuayriyah sits about 49 m above sea level (SRTM open elevation data), so surface runoff moves toward lower ground and can pool against balcony thresholds and drainage outlets. That means we pay close attention to falls, outlets and upstands rather than treating the slab as flat. For balconies we commonly compare a liquid-applied system with a bitumen membrane, and for bathrooms within the duplex we look at epoxy coating or spray foam depending on how much movement the substrate shows. Crack injection is priced per metre, and we measure every crack before quoting, since a single hairline crack can cost very differently from a long, active one.
Before the visit, ask the provider to walk the site with you and explain which areas they will inspect, including the balcony edge, the bathroom floor above the living area, and any cracks visible from below. Ask how they will identify the leak path, whether they will test with water before recommending work, and which system they propose for each surface. Request an itemised estimate that shows area or length for each element, using the per-unit ranges so you can see where the cost comes from. Finally, confirm how the work will be protected during the rainy season and what preparation you need to do, such as clearing furniture and planters from the balcony in advance.
In a duplex, the two floors often share lines, so tests are done floor by floor.
