Hao provided a free estimate. He took my design and ran with it. I needed something very low to no maintenance. I didn't want to be watering grass, pulling weeds, or mowing a lawn. Hao worked on my backyard himself with help from another guy. They finished the job in 4 days. They pulled up the dying lawn and laid down spaced pavers with gravel, artificial turf, and a LOT of river rock. Of course, they prepped the ground and laid down weed barrier as well. Hao is very friendly and courteous, and he was easy to work with. Highly recommend, great customer service!! read more
