Beware of this contractor!
I hire Evan to remove rocks and old grass and vegetation from my backyard and replace the front and back grass. He promised to add top soil, but he never did, just used the same that was there, the majority of grass died. When I checked under the dead grass I found that he did not remove even the fabric! he just put the new grass even over the rocks as you can see in the pictures, there is not even one full inch of top soil. Additionally the grass he used was full of weeds. I spent a fortune in water but without top soil and good a base it was impossible to recover it, I also hired a company for fertilizing and weed control. Of course he stop answering my messages after he realized of the problem. Do not waste your money or time with Evan, get a real company
