Hi, I’m tiling my kitchen floor (well, someone is for me), but he seems to be confused when it comes to staircase. Could someone enlighten me: old house, the bottom of wooden staircase is sitting on top of old tiles. I removed all old tiles but he told me to leave the bits that the staircase is sitting on and he will tile around it. I think that will look crappy, I want the tiles to run smoothly under it(stage staircase is kinda exposed), but when I remove old tiles now, the bottom will be hanging in the air a bit (probably around 1-2 cm, the thickness of current tiles with all crap attached to it). What is the professional protocol in this case? I would greatly appreciate some advice before he commences with the job, thanks
