We had a broken branch about 20 feet long, stuck in our 100 year old tree, about 40 feet up. The crew (two folks) arrived, wearing masks and standing back after knocking on the door. The two of them had a look to size up the job, provided a quote on the spot, I agreed to it, and they got started immediately.
The crew had appropriate safety gear. The longest part was tossing the lead line into the right place so they could climb up; but once they got that (after about 10 minutes), i was amazed at how quickly things went. The one guy climbed up, secured himself, then tied another rope to the broken branch. He cut the dead V that was holding the branch stuck, and then lowered it to the other guy on the ground. They had to work the branch around the phone and cable wires in the backyard. Then he cleaned up some other smaller deadwood while he was up there and came back down. Definitely not their first rodeo :)
The two of them then cleaned up the smaller twigs and branches that had fallen during their work, and took it all back to their truck. The 20ft branch was sucked into the wood chipper.
The crew was extremely courteous and professional, and they looked to enjoy their work, and also looked like they really cared about trees.
All in all, i was thoroughly impressed. I would definitely hire them again if we need any tree work.
