We have a very tatty 1960s parquet floor in our hall, previously covered by carpet , so the doors have a big gap at the bottom and the tiled floors on the other sides of the doors are slightly higher.
I'd originally planned to cover the parquet with some other sort of wooden or laminate floor, but the people who came to quote said they wouldn't do it because of the risk of the floor underneath "blowing" and the parquet will have to come up. Which sounds like an awful job and also increases the issue with the different floor levels.
So, now I'm thinking of back to carpet. ATM the stairs and all the downstairs carpet is the same, I don't like too many different carpets in a house. However the stairs is more worn than the rest so could reasonably be replaced on it's own. For the stairs I quite like stripes, but odd in the hall as well?
