I have a couple of weeks overlap before moving into my new house, and am getting some jobs done while it's empty.
The shower room has fully tiled walls. I noticed a couple of small cracks in the grout within the shower stall (consisting of 2 tiled walls and a shower door), near the bottom of the tiled walls. I can push a fingernail in these cracks. They're less than 1cm long and the gap is at the edge where the grout meets the tile.
Otherwise the grout looks ok, I've only noticed a couple of cracks but their location is in an area that is likely to be wet when the shower is used. The sealant looks fine.
So now seems a good time to deal with the cracked grout. I'm wondering if I can / should attempt this myself and if not, what type of tradesperson to ask.
