They did a big job all last summer on a yard across the street from me. They did a tremendous job but I'm sure it was super expensive because they went all the way to the waterfront.
As a neighbor I had a few complaints, excessive noise early in the morning, crazy dust clouds when the wind was blowing my way, employees blocking my driveway, but the owner responded promptly and actually fired one employee for and unspeakable act.
Last year was a very dry summer and they would blow the yard at the end of every day. The dust always seemed to blow my way.
They delivered a truck load of Hugh boulders before 7am one morning, sounded like an earthquake, woke me out of a sound sleep.
