These are the questions we hear most often before someone calls us for the first time. If yours isn't here, call (925) 321-2421 or use the contact form and we'll get back to you quickly.
Do you offer free estimates for tree removal and trimming in Tri-Valley?
Yes. Simply Trees provides free, no-obligation estimates on all residential and commercial tree work in Tri-Valley and surrounding areas. A crew member visits your property, assesses the trees in person, and gives you a clear price covering labor, equipment, and cleanup. There's no charge and no pressure to book.
Is Simply Trees licensed and insured to work in California?
Yes. We hold CA Contractors State License Board license #912462, carry full liability insurance, and have workers' compensation coverage on all crew members. That means if something goes wrong on your property, you're protected — something every homeowner should confirm before hiring any tree crew.
Do you have a certified arborist on staff, and why does that matter?
We have an ISA Certified Arborist on staff for every tree health assessment, pruning recommendation, and hazardous tree evaluation. ISA certification requires verified training and ongoing education — it's the standard that separates qualified tree professionals from general laborers with saws.
