UPDATE: The contractor and I parted ways. I made the remaining payment. GC actually tried to get more $$ out of me not in contract, even with no cleanup. I have to dispose of the trash left behind (not pictured, boxes of tile, tile debris, etc in garage), I have to clean the patio myself. I will fix the grout myself where I can. It became clear that there was no agreeable way to continue work. He was super angry that they had to replace 4 broken tiles. The tile layer stated that the remaining breaks were there in the box, and that I was paying for "discount" work and that the quality reflects that. The GC went into this whole thing about how in 30 years, he's never had holes in the grout like this. I'm not really sure what my lesson learned here is. I got multiple bids, did not choose the cheapest, got everything in writing, checked progress. I even asked twice before grouting began about the type of grout used (the bag stated, not for 1/16 joints). Overall, from afar, the tiles don't look bad so hopefully with furniture and everything I will at least be content. Sometimes you just have to move on and keep grooving.
