What to do next? (floor tile GROUT cracking)
What to do next? (floor tile grout cracking)
(This is about my familyroom floor tiles, but people have tiles in their kitchens, so I thought GWKitcheners would know.)
So the grout in my familyroom is cracking/chipping/separating. Terribly. All over/just about 70% of them.
One main cause is that my subfloor/joist is not sturdy/stiff enough.
Before install, my GC did tell me that my familyroom floor has some "give" to it, a bit springy. He told me that he would reinforce the joists underneath. And something about a flexible mortar.
Oh, do you think the heat of the radiant heating underneath is a factor?
--> So, what to do next?
Is it something that my GC should fix?
Or something I pay someone else to fix?
IÃ¯Â¿Â½m pretty unhappy about this. While the cracks/chips are not obvious until you look down (80% of the tiles are 18"x12", and 20% are 12"x12"), the grout should not be cracking/separating.
Appreciate your help/feedback.
