Hi, may I request for the catalogue and the quotation of the following : Currently I have a 4 piece casement window **** Room, which I want to change to 5 piece casement window plus a row of louvre on top. Similar also for 1 of my bedroom. I would be maintaining my current window grille. Btw, would there be any repainting of wall after the window changing? Thanks a lot.
