IBased upon the ratings here, we contacted Mr. Gullion (Andy) in March for a proposal and bid to install a mosaic glass tile back splash in the kitchen and to replace and/or install a new tile floor in a small bathroom. The initial appointment for the bid was informative but not very specific. Andy left with the promise to e-mail a detailed proposal, which we never received. We contacted him again in late June and he came back out to the house for another appointment. This time he gave us a detailed written proposal which we accepted. We decided to demo the bathroom floor ourselves, and we purchased our own tile, grout and sealer, at his direction, and he would install it. We were not informed that he would not be doing the installation himself. Even though we questioned his instruction to purchase sanded grout for the glass tile backsplash, we accepted his expertise as sufficient to follow his advise. On the agreed upon date and time, Andy arrived at the house with another installer. The associate was the one who did the work. The glass tile was put up and grouted. The floor tile was installed, and the installer advised that we use the dark grout that was used in the kitchen on the white tile floor in the bathroom as well. We had purchased white grout, but he was adamant that the dark gray would be best. He did so and left. Upon later inspection, it was horrible and we regretted that we hadn't stuck to our original choice. Also, the glass tile in the kitchen was scratched by the sanded grout, and there were several chipped and crooked tiles. We called Andy, he came over to look at the work, and agreed that the kitchen should have been grouted using unsanded grout and that the bathroom should have been grouted with the original choice of white grout. He brought in his crew to remove the kitchen backsplash and the gray grout in the bathroom. Additional tile and unsanded grout for the kitchen was purchased by Mr. Gullion and the work was done once again by his associate. This of course meant that the job took double the time planned. To his credit, Andy did not charge us any additional money for the removal and re-grouting of the bathroom floor and the additional bid price was eventually credited for the grout and extra tile. He was quite apologetic for the mistakes and very concerned for his reputation. We are happy with the work done in the bathroom. In addition to the floor, a wood threshold was installed to replace the broken marble piece that was there originally, and a custom plate was installed around the toilet water line. We are glad that we decided to pay to have this work done instead of doing it ourselves. We aren't so happy with the kitchen back splash. In spite of it having been sealed by the installers, the grout has discolored in the area over the cook top (probably they missed some spots when applying the sealer) and there are some crooked and chipped tiles in the installation. We hired this work done in the interest of saving time, but in retrospect, we should have done the work ourselves. If we were to hire Gullion Tile again, I would keep an eagle eye on any installation work and call out any mistake or concern immediately. This was the only contractor who would return our calls or show up for an appointment, so we don't have anything to compare the experience with. Andy seems to be a very honest and sincere man who cares very much about the approval of his clients. I feel comfortable recommending him, but with the previously stated oversight.
