I was first off impressed by the timely manner in which my phone call was returned and a free written estimate given. Trees Unlimited beats out four other companies in this phase.
My homework then began when checking on two personal/business references and the State of California for licensing and workman's comp coverage. Trees Unlimited checks out positively in all areas.
It is not often I/we can recommend so highly a contractor. Since then, we have told others about trees unlimited, and have been happily thanked for our referral.
