Last year I bought a room in the flat. It is an old room, all of 9 screens in net windows were broken. I had to replace all screens this summer. At first, I tried to replace them by myself. But I did not make it. Two net windows are between the room and the balcony. I can take off screen windows in the balcony. But the remaining 7 do not have the balcony. I have to take off screens without a balcony. It was difficult for me to remove screens of them. So I asked a specialist to replace screens. It cost 46,000 yen ($474.23 €353.85) for 9 windows.
