Marvin and his "team" started with the powder room, installing tile, an outlet, a vent light, a faucet, sconces, and a toilet. (Marvin did a lot of the work himself and seemed to only hire workers for things he could not do. His tile guy was his father who did the majority of the tile work, and there was one other worker who came for a day or two to help him). The work in the powder room was okay, except for incomplete installation of the outlet, the faucet (until a solution was found), the vent fan (Marvin cut into the ceiling too wide for the vent light to properly fit so it has fallen out and barely hangs). I also expected a better alignment of the sconces. The outlet was installed without a cover plate, and no escutcheon was installed at the water supply pipe for the toilet. But, the most concerning part of the powder room renovation was the poor installation of the faucet. Marvin installed the faucet with the escutcheon inside the wall, saying it was the only way he could connect the parts. Since the faucet was installed at a tiled wall, he then caulked around badly-cut tile to try to improve the appearance. He also advised that I should look for a replacement escutcheon, which was difficult to find. Eventually, after months, and after I was unsuccessful in finding a new escutcheon, a guy he brought on to paint moved the escutcheon over the tile (again, something Marvin previously said was not possible and necessitated unsightly caulking as the only solution in addition to finding a new escutcheon). We also incurred additional expenses hiring a plumber to further correct the poor installation so that the faucet spout would extend far enough over the sink bowl without splashing water on the countertop. As the issues with the powder room seemed fairly minor, we continued on with Marvin to complete the primary bath. Significant issues arose at tile installation when Marvin's dad and helper did a very bad job installing wall tile, as there were badly cut tiles and schluter trim, unevenness, and improper installation of schluter trim. We wasted materials that they damaged. The linear shower drain was installed slanted (crookedly), and when it came to the shower niches, there apparently was no preplanning to ensure the tiles aligned with the shower niches' placement and it all just looked like a mess. They couldn't even cut the schluter trim to properly fit--we purchased additional schluter for them to try to get it right, and finally we just realized they weren't capable. The shower niches were so badly done that my husband and I missed seeing the bad job done on the shower wall tiling until after the bathroom was completed and we had already paid Marvin. When I asked Marvin about the shower wall later, he said they should have used wall levelers but failed to get them. For the floor tiles, they installed a few cracked pieces, and we had to ask them to redo those. Less than a year later we started noticing holes and cracks in the grout in the floor tile, which worsened over time to the point where last winter we noticed movement in the tiles and one had actually popped up and was sticking out. In the powder room, we noticed holes in the grout in the wall tile within months. I tried reaching out to Marvin, but he stopped answering calls. Now, we have no choice but to repair the floor tiles and the shower wall tile.
