They Said About Us

  • I have used Stewart’s Tree Service on several projects in Napa and Vallejo and have been completely satisfied on every level.  Originally recommended to me by a friend in the east bay, Stewart’s Tree Service is knowledgeable, professional and completely flexible as the scope of the projects changed during the course of the project.  Pat is a certified arborist and his experience is vast so his team will take great care of you at a fair price.  I will most certainly call them the next time I have tree issues.

  • These guys weren’t playing around. Awesome prices, on time, and no lagging. They got in at the time they said, did a quick and professional job, and got out. So impressed. Will call on them again. Wow.

  • Over the past three years I have used three different tree service companies.  Stewart’s is by far superior to any of the other companies and I will continue to use them in the future.  The crew knows their “stuff”, which is comforting when a wrong cut can ruin the look of a tree.  The men are cordial, accommodating and so easy to work with.  My yard was perfectly cleaned up when they were done.   Recommend this company highly!!

  • Stewart’s Tree Service promptly responded to our request to have our tree pruned and brought down 1/3 from the top. We set a date the crew arrived and took care of this pruning, cleaned up everything and Pat gave us a great price.

  • I was very happy that my Chinese elm was pruned. I knew the yard maintenance people do NOT know how to prune or trim. They mow, blow, wack the bushes with the electric trimmer. That’s it! I love my trees as well as my beautiful bushes. I appreciate how Stewart’s has knowledge as to pruning and trimming. I am very pleased.

  • During busy season I got a quote for several trees. one being urgent large branch partially broken over neighbors house. Thy arrived on time, got that tree done at very competitive price and couple days. They worked/cleaned quickly and appeared to quite safe and did no damage in a precarious situation on a windy day. Will definitely schedule the rest of the 5 trees with them at a later date.

  • Stewart’s Tree service performed an outstanding job. They arrived early, and efficiently and competently cut down one tree and trimmed the other tree. They cleaned up the debris and chipped all the branches and leaves and left all that for us to spread in Rivertown. The front office personnel, Bryan Stewart and officer worker Pam, were so easy to work with and they answered the phone calls immediately. I called Bryan to thank him for an excellent job.
