Help - poor grout job by contractor? And what next?
We are finishing up having our only full bath remodeled. Now that the lighting is installed, we have seen the grout under good light (grouting was done a few days ago). I think it's pretty bad but could use input. I know there are not supposed to be cracks and holes everywhere (which we've got), but also surely the grout shouldn't look very crumbly and come off easily? It looks bad all over - holes, cracks, graininess, and some very low grout areas.
We have white subway tile on the shower & walls, and marble hex on the floor, with unsanded grout all over. The GC, not his tile guy, did the tile and grout.
Can this be fixed without regrouting? I'm not sure what to do at this point - withhold final payments until it is fixed, but what would be needed to fix it? Can he patch the holes? The all-over graininess is worrying and just looks really bad.
Thank you for any advice.
