This package is for residents who plan to arrange balcony glass washing at a certain interval but have not yet formed a fixed rhythm. As a first maintenance booking, it completes one full inner and outer two-side handling of balcony glass, frame and track clearing, and a basic acceptance record, while providing a reference for whether to continue arranging quarterly afterward. Reference price range: the first maintenance package is about EUR 65-130, close to the price structure of a single regular wash, the difference being that the provider briefly records current glass and track condition after completion so the resident can judge the next suitable visit timing. The custom stage allows the resident to state the desired maintenance interval such as quarterly, half-yearly or on demand, and the provider attaches a reference unit price for that interval to the quote sheet without tying the resident to later bookings. The deposit and balance still follow the single-visit flow: deposit after the slot is confirmed, balance after completion acceptance.
