When the glass conditions of two balconies differ greatly, such as one kept in good daily condition and the other untreated for a long time, charging by the same standard is neither reasonable nor matched to actual work volume. This package allows the resident to choose a work level for each balcony: one follows basic washing and the other follows deep washing, the two are merged into one booking, and the quote is calculated separately by level and then summed. Reference price range: basic plus deep double balcony total is about EUR 140-280. The custom logic is clear: the basic level covers both glass sides, frames and regular track clearing; the deep level adds preparation and extra rinse passes on that basis. The deposit is collected on the combined total, and the balance is paid after completion acceptance. During communication, the resident needs to describe the approximate condition of each balcony separately so the provider can judge which suits the deep level and which suits the basic level, and the quote sheet marks the levels separately to avoid confusion.
