How we count windows

One window means one window opening, regardless of the number of sashes or the size: a double-sash window is one window and costs 199 CZK. The price covers the glass on both sides, the frame and the sill. Pane size does not affect the price.

Box windows

In the older parts of Pilsen — the tenement houses of the city centre and Jižní Předměstí — box windows with two rows of sashes are common. Four glass surfaces are cleaned plus the space between them, where dust and insects collect over the winter, so they count as two windows. Please note it in the order: it matters more for scheduling than the window count itself.

Balconies and winter

A balcony door counts as one window. A glazed balcony is counted by individual openings, the same as windows in the flat. In winter we normally clean windows from the inside only, because water freezes on cold glass and products leave marks — and the price is lower in that period. Outside cleaning is better planned after the last frosts.
