This package is for duplex or split-level homes where upper and lower balcony glass needs to be handled together. The work route and equipment movement for upper and lower balconies differ from flat multi-balcony cases, so the quote includes reasonable work time for moving between levels rather than simply adding two balconies. Covered content includes both sides of glass on each level, frame and track clearing, and the reachable inner side of glass railing between levels. Reference price range: joint washing of upper and lower balconies is about EUR 130-250. During custom communication, the resident needs to state whether there is an internal stair directly to both levels or whether an external route is needed, so the provider can judge work order and whether the visit needs to be split into time blocks. The deposit is paid after the work plan is confirmed, and the balance is settled after both levels are completed and checked together. If some glass on one level cannot be handled on both sides from reachable surfaces due to structure, that part is marked separately in the quote and not counted as two-side billing.
