Mario gutted and installed new kitchen for us in 2015. Noticed 2 large tiles were getting stress cracks. I called to enquire and tray to get him to help me with the situation. All he said was you dropped something on them and I was the cause. I informed him that I dropped nothing on the tiles and that these were stress cracks not damage from something being dropped. Getting nowhere with him I said I will take care of it myself. Days later I noticed a odour coming from my crawl space directly below the kitchen sink. I opened the small door to find wet walls, floor and sub floor. Removed the kick plate below the sink to find there was a steady drip of water coming from a line we had him install for filling our hot tub. The water was steady dripping down the pipe and under the new tiles thus saturating the sub floor beneath the new tiles. With the sub floor now compromised it caused the tiles to succumb to stress cracks. When he installed the feed line for me from the cold water line he did not secure it and the line was able to be moved and knocked with things that were under the sink. If the piping was secured properly there would have been no movement and no stress on the joint where the leak was found. I proceeded to call him again to inform him of what I found and he was disinterested and not willing to help. We have used Mario for 3 renos now and I was more disappointed then mad that he wasn't willing to help me figure out this problem. He was satisfied in blaming me for dropping something on the tile which I did NOT do. I was not expecting him to do anything for free but I was hoping he would help and support me in this situation but he did not, he just blamed me. We now have a new contractor starting our last two renos and will get hime to look into the sub floor and tile replacement in the kitchen. Photos attached !
