I just paid a painter E600, to paint the largest bedroom in a 3bed semi-- I had removed old wallpaper, but he had to clean down from old paste, fill cracks etc- He did ceiling, walls, radiator, papered one section of room, did gloss painting of cupboard doors and skirting and door architrave- all for e600- But we supplied paper and paint...?
I am about to get him to do two other bedrooms, but they are so straighforward that I expect both to be E500 or so he has said--with me supplying the paint....(no old wallpaper nor special clean-down required)
Does that help?
