“Everything was fine. It was excellent. They did a great job. Everything went fine.”
“Very professional. Good conversation. They explained in detail what they were going to do and they did it. They removed a tree and took the stumps out. I'd give them an A+ overall. They also trimmed out two trees and cut a tree down. I'm looking at another tree and about two weeks ago I made sure I had their card, so I could call them back.”
“It's been a while, but it was fine. They did some tree trimming. I don't remember if they took one out or not. I know there were several that needed trimming. I would give them an A. They cleaned up nice and they were quick and careful. They were very good. It is very likely I would recommend them.”
“It was fine. They just took out a couple of shrubs. I'd give them an A. I would probably recommend them. It's a sentimental thing. I got them and then I completely forgot about them, so I don't know if I would recommend them or not.”
“They were fine. They were on time and they did it and got it done. They trimmed some trees. I'd give them an A.”
“I have recommended their company to someone I know who had scheduled to get his trees cut down that weekend. Tree removal and stump grinding. I'd give them an A.”
