You basicly have to watch them the entire time they are outside to make sure they don't damage anything or try to leave with the job incomplete. This is my experience with multiple companies they sent out. First ones did not do any edging at all. They had to come back out. The grass was hanging over the edge of the concrete. The edging facing the street was not done at all. I've had to wait days on multiple occasions for companies to come back and finish work. I've had then say they were coming out a certain day, did a no call no show, then contact me 2 days later. One company cut all my flowers in a small flower bed on the side of the house. One company that came back out to finish what they didn't do, LIED and said my grass was very tall and charged me extra. My lawn has HORRIBLE soil. I lived here 10 years and I am very familiar with how it grows. For my grass to be over grown, it would have to rain heavy for multiple days in a week then wait another week and a half to two weeks for it to be over grown. I had no one else to cut my lawn, so I had no choice but to use them until the Fall. Best believe I took pictures of my lawn every time before they came out incase they lied or caused any damage which is what I SHOULD NOT have to do.
