This page explains the window service in Krakow. We agree the scope after checking the frames, because a window that rubs against its frame needs different work than one whose seals have gone. The quote comes before the work starts.
If you only need the glass washed, go to the window cleaning price list — that service is charged per sash.
Adjustment and new seals cost a fraction of replacing a window, and in many cases they are enough to restore the frame's tightness completely.
The price is set individually and depends on how many windows there are and how much work each needs. You see the quote before the job starts.
Very often, yes. Replacing the seals and setting the compression correctly restores tightness without replacing the whole frame.
They set how firmly the sash presses against the frame. In winter the compression is increased to reduce heat loss; in summer it is eased off, which takes the strain off the seals and extends their life.
The service covers adjustment, sealing and hardware. Replacing a glazing unit is quoted separately once we have checked the dimensions and glass type.
Adjustment alone is usually a matter of minutes. Replacing the seals on a whole window takes longer, depending on how the frame is built.
