We recently had a storm damage job (on a tree we recommended them to take down two years prior); half the tree failed, we were hired to remove the damaged and remaining portions of the tree. Working there previously, the neighbor was really snooty about his grass, throwing limbs from the clients sycamore that had fallen into his yard in the weeks before we pruned the tree; his lawn is mostly covered with shade, and he kept it very very long.
Anyhow, we do prioritize our storm damage, and got to the job within 4 days of the quote, and the night before we completed the project, the rest of the tree fell into the neighbor's yard; I knocked on his door, but he was gone, so we cleaned up the whole tree, including what was in his yard, and even used the blower to fluff his turf up. The tree had caused 3 divots which you couldn't bury an apple in, which we didn't fix because we didnt cause them during our work.
He sent me an email and called wanting me to hire a landscape contractor to come in and repair his lawn, wanting it rolled out and overseeded etc etc, accusing us of using a skidloader or some other heavy equipment to move the tree. I explained to him that the tree had fallen into his yard, and that although the neighbor could have had us cut it off at the property line and leave it for him as an "act of God", that they wanted to be good neighbors and have us clean the whole thing up as originally planned.
He dropped the issue with me, but wanted to know how to repair the way the grass looked "laid over" -- Mow it. lol
