Sub-standard work - spalling heaving lifting stones.. water under stone work. He was well aware of the issue prior to getting paid and assured me he would return to fix it when the weather turned in the spring.. He has never shown up to fix anything.. never _ told me he would over and over and never did - 35 emails and text messages and even showed up twice to look at it and never lifted a finger to fix anything. He also left a mess behind for me to clean up.. a big mess.. concrete, bricks, stones all over the place. He said he would clean it up.. but didn't do that either.
