Very friendly (everyone), very reasonable prices, professional, and great service. I hired Enviro Tree Care to prune and trim a large sugar maple (about 40-45 foot high) and to chop a dead elm tree. Not only did they do what they said they would but also did some extra stuff for free. Anson noticed I had three stumps in front of the house and just said "they should at least be chopped to the ground level, we will do it. No charge." I mentioned to him my plan to make a child swing, he said "we will throw in a rope, no charge!". The only thing I would recommend is if you really want to make firewood pieces out of the tree and the size matters, then be specific with the sizes and let them know. It was mentioned in the air I needed the logs to be about a foot to a foot an a half, and some (about 4 pieces), specifically the dead elm, were left at about 2 foot long (some longer) and 9 inch thick pieces which makes them hard to deal with especially if you don't have a circular saw to cut dead wood.
Though I personally didn't mind it - I found different use for them - but if you are someone picky, this might be something to consider mentioning and asserting from the beginning.
By the way, they also gave me an extra discount because I got my neighbor to use their services too - just another plus.
Would I use their services again? Definitely.
