We needed our 100 sq ft foyer tiled. At first, Alex was professional. Tiles were laid out nicely except for one tile which significantly showed a lip. Alex assured us that if there were any problems, he would come back to fix it. We held him to his word. After waiting patiently for 2 months and the amount of stress we had as this stopped us from continuing our renovation (numerous promises to return to fix it were made but he never showed up; excuses one after the other), we ended up hiring someone to fix his mistake. It's unfortunate that he does not guarantee his work.
