First of all, please learn how to cut trees. Just because you have a truck and a grinder and a bunch of chainsaws doesn't make you a tree expert. First off, I requested a certificate of insurance and after the job was stopped due to an unfortunate accident (I will explain)I asked them for their insurance and they informed me they didn't have it. Luckily no one was hurt, but according to people that I have talked to and have seen pictures and videos of the event, I was very lucky. They came in and began by cutting one of the largest trees (they were hired to cut 5 in total). That big one was about 40 feet from our house and they cut it by first cutting a wedge in the front and them cutting behind the wedge. It fell without incident. The second was pretty much the same, but it did come closer to our house. I just thought "wow these guys know what they are doing." The third one was close to our house so they tied a rope to the top of the tree, hoping to pull it in the direction they wanted it to fall using their truck to pull it with the ropes since it was leaning toward our house. When they started cutting it, using the same wedge method and not cutting from the top and lowering pieces, I was looking on in wonder. I was amazed that they knew what they were doing. This wonderment turned to shock when I saw the tree falling in the direction of our neighbor's house. It destroyed his shed and fence. Luckily their was no one outside and that it did not drop in any other direction because it would have destroyed either house. Mind you, if it would have fallen a few degrees to one side of the other it probably would not have mattered. But their method had it falling a full 90 degrees off their intended drop and caused extensive property damage.
I would not use these people to cut my grass, let alone a tree on your property. They lied about their insurance coverage (which is illegal) and they could have caused so much more damage due to their inexperience and poor workmanship. Don't use these guys.
