Frequently Asked Questions — Tree Service in LA & Ventura County
Tree removal costs in the San Fernando Valley typically range from $500 to $5,000+ depending on the tree's size, location, species, and accessibility. Small trees under 25 feet usually cost $500–$1,200, while large trees over 60 feet can run $2,500–$5,000 or more, especially if crane work is needed. We provide free on-site estimates so you know the exact cost before any work begins. Call (818) 717-8787 for your free estimate.
Get a free estimateIt depends on your city. In LA City, you generally need a permit to remove protected trees like oaks, sycamores, California bay laurels, and any tree over a certain size on private property. Cities like Pasadena, Beverly Hills, and Burbank each have their own tree ordinances. As ISA Certified Arborists, we help homeowners navigate the permit process and can prepare arborist reports when required.
Learn about arborist reportsAn ISA (International Society of Arboriculture) Certified Arborist has passed a rigorous exam covering tree biology, diagnosis, maintenance, safety, and management. Fewer than 5% of tree care workers hold this credential. Our owner Juan Bautista holds ISA certification WE-12613A and is also a Certified Tree Safety Professional (CTSP #022097), ensuring every job follows industry best practices.
Why credentials matterMost trees in Southern California can be trimmed year-round thanks to our mild climate. However, the ideal window for major pruning on oaks and other deciduous trees is during dormancy — late fall through early spring. We recommend trimming before Santa Ana wind season (October–December) to reduce the risk of branch failure. Palm trees are typically trimmed once or twice per year.
