At the heart of our mission lies a commitment to our community


We offer comprehensive tree services across the entire Oahu, Hawaii.

When seeking tree services, consider quality, reliability, and experience. HTM Contractors has over 30 years in the industry, offering services from tree pruning to stump grinding. It’s essential to look for professional certifications, licenses, and a company with a robust safety program. Ensure the company has the correct insurance and is available to answer any related questions.

Our arborists are highly trained professionals who have obtained certifications from reputable organizations in the field, such as the International Society of Arboriculture (ISA).

They undergo rigorous training in all aspects of tree care, including safety procedures, tree biology, diagnosis of diseases, pest management, and proper pruning techniques.

Additionally, our team regularly participates in continuing education programs to stay updated with the latest advancements and best practices in arboriculture. This commitment to professional development ensures that we deliver the highest standard of service and expertise to our clients in Hawaii.

If your trees are not accessible by truck, we employ various specialized techniques and equipment to reach them.

This may include manual climbing methods and portable machinery, ensuring we can provide comprehensive tree care regardless of accessibility.

Our team is trained to handle these scenarios safely and efficiently, minimizing any impact on your property while delivering the same high-quality service.

Please contact us at 808-425-9060 to discuss the specific details of your situation, and we will devise a tailored approach to meet your needs.

Tree work is inherently risky and should be handled by a licensed professional. Liability insurance protects homeowners and their property, while workman’s compensation insurance safeguards tree professionals during work. Hiring a non-licensed or non-insured company can make you liable for damages or injuries. Always request proof of insurance and a valid contractor’s license before starting any work.

HTM Contractors prioritize property protection. We use protective materials over sensitive areas and have experienced teams skilled in various removal techniques, ensuring minimal landscape impact.

Reputable tree service companies such as HTM Contractors are insured. In the rare event of accidental damage, the company will work with you to ensure repairs or compensation.

Always inform your tree service provider about any pets or children. Most treatments are safe once dried, but it’s essential to keep pets and children away during the application and until the provider gives the all-clear.

In Hawaii, the solutions used for vascular injections to treat palm trees against the Coconut Rhinoceros Beetle (CRB) typically contain insecticides specifically approved for use in palms. These treatments include:

  1. Imidacloprid: This systemic insecticide acts as a neurotoxin to the beetles. It is absorbed by the tree and distributed throughout its tissue. The feeding beetles ingest it, which effectively reduces CRB infestation.

  2. Emamectin Benzoate: Known for its effectiveness against a variety of pests, including CRB, this systemic insecticide poisons the beetles as they feed on the tree’s tissues.

Our application of these insecticides through vascular injections ensures direct delivery into the tree’s system, maximizing effectiveness while minimizing environmental impact. Our team strictly adheres to the safest application practices to ensure the health and longevity of your palm trees. Please contact us for further details on our treatment protocols or to arrange for a professional consultation.

A healthy tree typically has vibrant foliage during its growth season and shows no signs of damage or disease. Regular inspections by a Certified Arborist can help spot potential issues. Trees displaying unusual signs, like premature leaf drop or discolored leaves, might need attention.

Regular tree inspections can prevent potential hazards and ensure the health of your trees. It’s recommended to have a professional arborist inspect your trees at least once a year, or after major weather events like storms or hurricanes.

Signs of disease or pest infestation include discolored leaves, holes in the bark, sawdust at the base, or unusual insect activity. If you notice any of these signs, contact a tree service professional immediately.

After a storm, check for broken or hanging branches, split trunks, or leaning trees. If you notice any of these signs, keep a safe distance and contact a tree service professional for an assessment.

Pruning is essential for safety, aesthetics, and tree health. Dead or broken branches can be hazardous. If branches grow too large or close to structures, they should be pruned to prevent damage. Pruning can also enhance a tree’s appearance and provide better views. Always use a Certified Arborist for pruning to avoid potential damage.

The time it takes to remove a tree depends on its size, location, and the surrounding environment. While smaller trees might take a few hours, larger or more complex removals can take a full day or more.

Always request detailed estimates from multiple providers. A reputable tree service company will provide transparent pricing, explaining the costs associated with each service.

Crown Reduction

Crown reduction is a crucial service for maintaining tree health and safety.

Our approach carefully reduces the size of a tree’s canopy while preserving its natural shape and structural integrity.

This service not only improves tree health and longevity but also reduces potential hazards, ensuring a harmonious balance between nature and the surrounding area.


Trunk injection of trees is a way to efficiently treat many different insect and disease
problems, as well as nutrient deficiencies, in a manner that limits environmental exposure.
This method also uses the least amount of pesticide as compared to other conventional
treatment methods.

Trunk injection involves using a special injection tool which places and seals the insect
control directly into the trunk where it is quickly taken up by the vascular system and
distributed throughout the tree.

The photos in our gallery illustrate these injections being used specifically to combat the coconut rhinoceros beetle,

Land Clearing

Our land clearing services efficiently prepare sites in Hawaii for development and emphasizing environmental responsibility.

We have the necessary equipment to clear trees and vegetation for both small and large projects, including a mulcher that can process wood into wood chips for reuse on-site.
