Tree Removal
$1,350
John is an incredibly knowledgeable arborist who clearly understands trees and the issues they face here in Colorado. We had two pines that he ended up removing and replacing with Junipers. He gave us options to treat or replace. John took the time to walk through both options plus provided several tree replacement options to chose from. Highly recommend his expertise and honest approach.

In our backyard we have a favorite tree, George, a purple ash, who desperately needed some trimming. John and his team came over and we discussed how we wanted it done, visual and health wise. John trimmed George wonderfully and cleaned up the branches. A very positive experience!

John was very professional, timely, and respectful. We had him out to our house in June to inspect for pine beetle concerns. He professionally answered our questions and was not pushy to sell his service. We opted to use Verbonone pouches to protect our trees, and he helped make suggestions on how, when, and where to place them to protect our property from nearby infestations. We had a few trees on our property that had been victims from pine beetle kill. He make recommendations on how to address and stop the spread. We did the work ourselves, and he did not ask for anything. We gave him a small payment for coming out and offering advice, but he did not ask for it. We had him out again this week to cut down a mature aspen tree that we had to take down due to insurance requirements. It was a sad day for us because we loved the tree. John came out to evaluate our options on saving it while satisfying insurance. Ultimately, we had to take it down, and John came out a 2nd time to complete the task in a very timely and professional manner. We highly recommend John.

John and Carson did a great job taking out three trees from my front yard. John was prompt, communicated well, and took the time to clean up as much as possible afterwards.
