  • 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.   Thomas, Discovery Bay, CA
  • 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!!   Susan, Walnut Creek, CA
  • 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.   Andrea, Healdsburg, CA
  • Stewart’s tree service did a fabulous job removing four 50' foot pine trees from our residential backyard.  They were on time, and very professional in their approach to this tricky job.  They were careful and very tidy - an absolute pleasure to work with on this project.  The cost was extremely reasonable, and if we need any more trees removed, we will certainly call them back.  I highly recommend Stewart's Tree Service to anyone wishing to remove a single tree or a whole grove of trees.
