Hi. Any advice would be much appreciated. We have a quarry tile kitchen floor laid on ash. Whilst I like quarry tiles, over time the floor has developed undulations, several tiles have cracked and others are damaged, not to mention that it is cold, especially as it is on the north side of the house. We are replacing the kitchen so thought this was a good opportunity to replace the floor. However, the more I read, the more concerned I become about the best way to do it and possible complications with damp! The rest of the house has suspended floors. Does anyone have any experience or thoughts on the matter please?
