No Time for Do-It-Yourself Landscape Projects? Hire a Professional!

Tips for hiring landscape contractors:

Get at least three estimates. Ask for a written estimate with all associated costs, scope of work, and a timeline.
Check references.
Ask for professional certifications.
Make sure they are licensed, bonded, and insured.
Check out the Arizona Registrar of Contractors’ (ROC) website - http://www.azroc.gov/ to see if they are a state-licensed contractor. You also can find out if the Arizona ROC has received complaints about a specific contractor.
