I have 2 big trees - one in the front of the house and one in the back. Living in a row of townhouses, I am in the middle and therefore have no side entrance to get to my backyard.
This was not an obstacle for Derek and his crew. With my neibghbour's permission (2 doors down that does have side entrance), they were able to trim the backyard tree and just toss the branches over the fences without any incendence. Derek showed up on time (as I heard the chain saw buzzing at 08:25 and they were to be here for 08:30) and that is impressive (being on time says a lot about a company).
They were courteous, polite and cleaned up after they were done.
