I have a very big tree between buildings that need the top branches cut back. About 6 to 8 feet of limbs need to be cut, so like about 4 to 6 inch diameter. You will need a 40 ft ladder or be a great climber. Looking to get this done in the next 2 weeks. The job in on Montpelier ST. I can meet anytime if you want to look at the job.
