I was referred to Seattle Tree Preservation by an arborist that I have hired over the years to protect our trees and to prevent our neighbors from needlessly removing them. This is my second year that I have used the firm. The first year they removed a dead tree and did some minor trimming to enhance my view. I was very satisfied with this work. This year I hired them to trim 10+ large trees (all over 100') to open up view windows without damaging the trees. The results were great - I discovered that I had water and mountain views - and they were careful and judicious in helping me define the scope of the project so I would get the maximum benefit from the work. It was on our hourly basis and they didn't try to upsell the project. They also did a bonzai trim of an evergreen that was exactly what we wanted - trimmed from the bottom up,correctly trimmed a number of our other shrubs that were overgrown and needed to be reshaped (not given a haircut) and raised up a number of trees that were encroaching on our drive. Their charges were very competitive, they called to alert me when they could do the work and they showed up on time. I will use them in the future for any tree/shrub work I require.
