This package is for residents with three or more balconies who want one unified quote rather than comparing several single figures. The custom core is summarized calculation: the provider calculates a base price for each balcony from glass pane count, railing linear meters, track length and reachable conditions, then merges them into one total quote, so the resident does not need to combine several single numbers. Reference price range: bundle washing of three to four balconies is about EUR 150-300, depending on total glass area and work complexity. A bundle quote does not mean all balconies are simply multiplied by the same unit price: balconies with poorer reachability or heavier dust are shown as differences in the itemized lines, but the total does not change after confirmation because of the internal calculation method. In the flow, the resident submits brief information on each balcony and receives a quote with itemized lines and total side by side, confirms the scope and pays the deposit, and pays the balance once after all work is checked. If some balconies are judged after assessment as not within the scope that can be completed in one service day, the provider states this honestly and suggests splitting rather than forcing them into one booking.
