This company is excellent. Carter, who did the estimate, was clear and helped me understand why certain trees would be appropriate to cut down, while others weren't. The price seems fair and when I got another bid they were within less than 10% difference. I felt like the fact that they are certified arborists gives one the sense that they really know what they are doing.
The owner of Tree133 came quickly, and gave a very informative and fair bid to remove branches from our large Douglas Fir trees after the big wind storm. Other bids were higher, or some we called never responded. He and his crew were very professional before, during, and after the work was completed. We believe that the best service comes from locally owned and operated businesses. We Highly recommend Tree133 for any tree trimming or pruning ! Chris & Jane
Tree133 is a fantastic company. They are excellent communicators and they are reliable - we made an appointment for getting a quote, and later for getting the work done, and in both cases Tree133 arrived on time and ready to get to work. They sent email and text messages and reminders throughout the process. For both the quote, and on the day when the work began, staff took the time to answer all your questions and give advice on best approaches for maintaining the trees and large bushes in our yard. They prioritized doing what is "best for the tree" rather than just cutting it down. We were so pleased when we were assured that one of our trees that had lost a large branch, would be just fine - that all it needed was some careful pruning and shaping. Everyone in the field is a certified arborist and if you work with them, you'll know your yard is in good hands. We found everyone we dealt with to be 100% friendly and knowledable. Our trees and large bushes look great now. I've recommended Tree133 to several neighbors and friends because they are a stellar company and always seemed to go the extra mile. Give them a call, you'll be glad you did!
Tree133 was a pleasure to work with on my tree project. They are prompt, professional, informative, and easy to reach if you have questions or problems--which I did not--but it's nevertheless good to know. They did excellent work, on time, and for what I think was a reasonable price. I would definitely use them again.
Tree 133 brought great knowledge and skill to our project. They took the time to answer our questions about different cabling systems and the pros and cons of each. The team was professional, kind, and communicative throughout the process. They also followed up to make sure we were happy with how the work turned out. We plan to use their services again next time we need an arborist.
