I had a complete backyard renovation that took over 3 weeks and 8 guys only to find out that they did not put anything underneath the rocks to prevent weeds and now my backyard is infested with weeds. I spent over $25,000 to get shoddy workmanship. Every landscaper I have hired to remove the weeds said that Distinctive Exteriors should have put something between the dirt and the rocks to prevent all of the weeds but they didn't. Buyer beware! This is impossible to fix permanently.
