TREEMASTERS is a licensed contractor in the state of California and because of this, TREEMASTERS is able to be a fully bonded and insured company.  We are insured for Workers Compensation, Automobile and General Liability.  This fact is important to you, our client, because part of providing superior customer service is being able to protect your property and personal safety in case of an incident while we are on the job.

TREEMASTERS is insured with over $7 million in coverage to provide our clients with confidence and assurance.

It is important for you as a consumer to ensure that any contractor you hire is licensed, bonded and insured.  While most contractors in California take instance requirements and worker’s compensation matter seriously, there are those that may cut corners in an attempt to save money.  For this reason, TREEMASTERS strongly recommends checking the status of any contractor you hire, and ensuring they have sufficient insurance and worker’s compensation coverage.  However, insurance coverage alone is only in place to safeguard the client and contractor if there is an incident, and does not guard against an incident occurring in the first place.  For this reason, TREEMASTERS utilizes a comprehensive safety program with all of our tree workers to help ensure ANSI and OSHA approved safety measures are followed on each of our jobs and to promote safety in the workplace.

It is also important when hiring an arborist to know that their certification has not expired, lapsed, or been revoked. I.S.A. Certified Arborists must undergo continuing education and training in order to keep their certifications current and active. Some arborists may receive their initial certification but neglect to participate in the continuing education and allow their certifications to lapse, but will still advertise themselves as Certified Arborists.

Before you hire ANY Certified Arborist, please verify their certification status at the International Society of Arboriculture website. You can search by the certification ID number, location, postal code, or last name.

The industry standard for General Liability Insurance coverage is $1 million.  As property values rise, so has the need for increased insurance coverage.  At TREEMASTERS, we felt it was our obligation to our valued clients to ensure that any incident, big or small, would be covered and our clients would have no cause for concern, therefore we are insured with $7 million in General Liability Coverage.

Listed below is TREEMASTERS’ insurance coverage package, with a brief explanation of what it does to protect you, our valued client.

GENERAL LIABILITY COVERAGE – $1 Million + $6 Million in Umbrella Insurance

General Liability insurance covers any structures and people in the area in which we are working.


Our Umbrella Policy coverage supplements our General Liability insurance coverage, meaning that if an incident exhausts the limit of the first policy, there is sufficient coverage available to remediate any claim.


All of our trucks and equipment are covered under this Automobile Insurance policy.


If an incident affects one of our employees while working on your property, our Worker’s Compensation Insurance will bear the cost of treatment and protect you, our client.

In addition to our Worker’s Compensation Insurance, TREEMASTERS offers all of our full-time employees full health benefits.
