How long does window replacement take?

The installation itself usually takes one to two days for a house. Before that come the measurement visit, the quote, any Klimabonus and 3% VAT applications, which must be made before the work starts, and then made-to-measure manufacturing. The total time depends mostly on manufacturing and the paperwork.
