I could of course take the whole lot out and put (expensive) hanging/sliding doors like the new wardrobe we've just ordered. But as funds are tight I'd like ideas and recommendations for dealing with the 6 sliding doors we've got, for instance, is it practical to put any rollers on? Merely clean the guides and sand the bottom of the doors smooth? Add PTFE?
2) We have no kitchen door. It's a bit tight to have a door swinging inwards (which is how it probably was) and not practical to have it swing outwards into the adjoining dining area.
A sliding door seems to be an option, though others may have different ideas. I would however like to have a fit that prevents kitchen smells and noises from drifting into the dining/lounge area.
