I'm not sure that the work from A Small World Tree Co. is perfect but it is close enough. The company is great and they do great work but the biggest problem has been scheduling because they are really busy and so they schedule way out. Other than that, as far as I'm aware its been pretty successful.
My previous experience with them was at my house and it was also really good. The only problem was probably having a little bit of lose ends because they were working with someone else there. They had another person that had hired them to do work. Overall, they are polite, professional and reliable.
