Buying a house with a staircase like the picture below but complete with thick dark green carpet on each tread, and the wood is a darker brown stain/varnish. It's all a bit creaky too, but what should I do or what could I do? What do I need to know? I want to remove the carpet but what then? Paint it? (that's a LOT of sanding!) Does it need checking out for safety? Ideas/advice welcomed!
