Guastucci Tree Service

I’ve used these guys for over 10 years at my house in San Anselmo. Steve and his crew always do top-​notch work: they arrive on time, do the work quickly and efficiently, and completely clean up afterward. They don’t cut corners. I also rely on their advice for tree care, watering, etc… they’ve never steered me in the wrong direction!
I trust them to do a great job, and I enthusiastically recommend them to anyone I know who needs tree work.

I have been using Guastucci’s Tree Service for at least 15 years, if not more. He always gives me what I think is a fair deal, his workers are with him long term, they know what they are doing and don’t hack my trees up — they keep my oaks beautiful, my sycamores just the way I like them. If something doesn’t need work (but I think it does) he tells me… he and his people are trustworthy, reliable and knowledgeable.
I just wish he wouldn’t make me always get a permit from the Fairfax Tree Committee… LOL

Guastucci Tree Service pruned and cut my neighbors trees. The day after they left, I noticed so much leave debris left on my property and my neighbors adjacent to the cutting. I was upset and spoke to the person in charge of the Co. in Fairfax and they said they would send someone out to clean the debris that their workers left. I finally had to clean it myself. Guess what their debris is still flying around the neighborhood? Since I spoke with the Co., no one came out or cared so my alternative was to give them a bad rating and maybe they will clean neighbors properties too, in the future.

On March 1^st we had a tree come down on our house. A big oak tree that took out another tree in the process. Within an hour of the they had a crew there to review the situation, bring in the appropriate machinery to make everything safe and reduce the chance of additional damage being had. Always present and with professional direction as to how to best resolve a devastating situation. These guy get my vote 100% of the time.
I have also had Steve give me good advice on maintenance and care of other trees and what was needed to maintain a healthy ecosystem.
Expedient, hard working, ethical, and knowledgeable.

They took a tree out of my back yard that was making my fence lean. They did a good job and were fast.

My 4 oak trees (2 are heritage so they are all very big trees) were poorly maintained by the previous owner of my house. I have had oak moth (eats the leaves of the valley oak during spring) and sudden oak death as well as other no-no’s like an irrigated lawn next to the tree trunk, buried crowns, etc.
Steve has often come to my home at no charge when I have had questions just so he could take a look. He has done all the crown clearing as well as regular deadwooding to keep them healthy. He also recommended a tree specialist who treated the sudden oak death by removing the canker and spraying. That work was done last summer and so far, that tree looks like it is still going strong. Steve is dead honest and will often state when certain procedures can be safely delayed to save money.
