The City of Westminster does not have a tree care company licensing program, but neighboring cities do (please note we do not endorse any companies on this list):

How to hire a tree care contractor:

  1. Get three or more detailed bids from different companies in writing
  2. Check contractor’s credentials and ask for proof of insurance – ask if contractor employs International Society of Arboriculture (ISA) certified arborists and verify using this tool
  3. Never pre-pay contractors for tree work
