Why Hire a Certified Arborist

Hiring a certified arborist offers several key benefits that ensure your trees are in good hands. In this post, we’ll break down what sets ISA Certified Arborists apart and why their expertise is crucial for keeping your trees healthy and happy.

What Is a Certified Arborist?

When it comes to maintaining your trees, it’s important to work with someone who truly understands tree health and tree care. A certified arborist is a tree care professional who has completed rigorous training and certification to ensure they have the knowledge and expertise to handle your trees’ unique needs. This exam and certification is administered by the International Society of Arboriculture (ISA). Achieving this certification means that the arborist has met industry standards and is well-versed in the most up-to-date tree care practices (they have changed over time!).

Certified arborists are committed to ethical practices, proper tree care, and safety. Their knowledge spans everything from tree biology to pest management, ensuring your trees are treated with the best care possible.

Whether you’re dealing with a damaged tree, want to improve your landscape, or need professional advice on tree health, hiring a certified arborist ensures your trees are in capable hands. Thomas J. Tree and Garden Care is a trusted choice for certified arborist services, offering professional care to maintain your trees’ health and longevity.

ISA certification involves continuing education and practical experience to ensure arborists stay up to date with the latest tree care techniques and advancements.

The Benefits of Hiring a Certified Arborist

Hiring a certified arborist brings numerous benefits that ensure the long-term health of your trees. Here are some key reasons why their expertise is essential for proper tree care:

  1. Expert Knowledge and Training: With extensive training and testing, arborists gain a deep understanding of tree biology, disease management, pest control, pruning techniques, and environmental factors. This expertise allows them to provide the best care for your trees, based on science and best practices.
  2. Standardized Care Backed by Science and Research: Certified arborists follow scientifically backed practices based on the latest research in arboriculture. This ensures they provide proven, effective solutions rather than relying on guesswork. This approach is crucial for accurately diagnosing tree diseases, pests, or growth problems.
  3. Proper Tree Health and Risk Assessment: An understanding of tree biology, disease management, pest control, pruning techniques, and environmental factors allows certified arborists to assess the health of your trees and identify potential risks, ensuring they receive the best care based on proven methods and industry standards.
  4. Greater Familiarity with Tree Species and Anticipated Growth Responses: Certified arborists understand the unique needs of different tree species. They know how each tree responds to pruning, changes in the environment, and different care techniques, ensuring your trees get the right care for their specific needs.
  5. Preventative Care: Some trees need special pruning or are more prone to pests. Certified arborists understand these key details, helping prevent mistakes like improper pruning or planting in the wrong spots that could be harmful.
  6. Safety: Tree care can be dangerous, especially when it comes to pruning or removing large trees. Certified arborists are trained to handle the proper equipment and follow strict safety protocols. By hiring a professional, you reduce the risk of injury to yourself, your property, or anyone nearby.
  7. Compliance with Local Regulations: Many areas have specific regulations regarding tree removal, pruning, or care. Certified arborists are familiar with these local rules and can help ensure that all work is done legally and by municipal or environmental guidelines. This helps avoid fines or legal issues later down the line.
  8. Comprehensive Services: Certified arborists offer a wide range of services beyond basic tree care, including risk assessment, tree removal, root excavation, and emergency services. Their broad skill set allows them to address any tree-related issue that may arise, making them a one-stop resource for all your tree care needs.

Certified Arborist Tree Services: What’s Included


Certified arborists offer a wide range of specialized tree services to ensure the health, safety, and aesthetic appeal of your trees. These services typically include:

  • Tree Pruning and Trimming: Proper pruning helps your tree grow healthier and stronger, removes dead or diseased branches, and reduces the risk of falling limbs.
  • Tree Removal: Sometimes a tree must be removed. Certified arborists can safely help with this, minimizing the risk to your property and surrounding trees.
  • Tree Planting: Choosing the right tree and planting it correctly sets the stage for healthy growth. Arborists ensure the best start by selecting suitable species and using proper techniques.
  • Tree Health Assessments: Arborists can inspect your tree to check for problems like pests, diseases, or structural issues that might need attention.
  • Stump Grinding and Removal: After a tree is taken down, arborists can grind the stump, preventing lingering problems like pests or fungus. This also clears the area for new plants or grass.
  • Emergency Tree Services: Storms and strong winds can lead to tree damage. Certified arborists offer emergency services to deal with fallen trees or broken branches, safely removing or stabilizing them to prevent further damage and ensure your safety.

These services, backed by the expertise of certified arborists, ensure your trees receive the proper care they need to grow strong, healthy, and safe for years to come.

Best Certified Arborist Near Me: How to Choose the Right One


When looking for a certified arborist near you, it’s important to consider several factors to ensure you’re hiring the right professional for the job:

What to Look For:

  1. Certification and Experience: Make sure the arborist is ISA-certified (International Society of Arboriculture) and has the necessary credentials and years of experience in the field. Certification demonstrates a commitment to high standards and ongoing education.
    • *Extra Tip: You can confirm a certification and find qualified arborists in your area by visiting the ISA website (isa-arbor.com) and using the “Find an Arborist” tool. Just enter your zip code or city to view a list of credentialed professionals near you. You can also check online, searching under “arborist” or “tree service.” Look for accreditation with the ISA or ASCA.
  2. Services Offered: Ensure the arborist offers a wide range of services tailored to your needs, such as tree pruning, removal, health assessments, and pest management. A well-rounded arborist will be equipped to handle various tree care needs.
  3. Insurance: Make sure the company is bonded and fully insured. Ask to see certificates of insurance that include coverage for liability (to protect against damage to your property or a neighbor’s) as well as workers’ compensation. For added peace of mind, contact the insurance provider directly to confirm the policy is current and active.
  4. Reputation: Look for reviews, testimonials, and recommendations from previous clients. A trusted arborist should have a proven track record of providing quality services and customer satisfaction.
  5. Local Knowledge: Arborists familiar with your local climate and tree species can offer more accurate advice and care, making them a better choice for ensuring the health of your trees.

What to Watch Out For

  1. Door-to-Door Salespeople: Beware of door-knocking salespeople, especially after storms or during outbreaks of invasive tree species. These salespeople are often nonprofessionals looking to make quick money by relying on fear tactics.
  2. Bargains/Time-Sensitive Deals: Avoid being pressured by limited-time offers or so-called “bargain” deals. Reputable arborists won’t rush you into making a decision.
  3. The Lowest Bid: While it may be tempting to go with the cheapest option, lower costs often reflect a lack of experience, proper equipment, or insurance. Quality tree care is an investment.
  4. Paying in Advance: Never pay for services upfront. A trustworthy professional will provide a written estimate and accept payment only after the work is completed to your satisfaction.
  5. Climbing Spikes: A responsible arborist will avoid using climbing spikes on trees that are meant to stay in the landscape. These spikes can cause damage that leaves the tree vulnerable to pests and disease.
  6. Tree Topping: An ISA-certified arborist will never recommend “tree topping,” which involves cutting off the top of a tree. Though often done to reduce height or risk, it leads to weak, fast-growing branches that are more likely to break. This short-term ‘solution’ may lead to increased risk in the future.

By carefully evaluating these factors, you can find a certified arborist who meets your specific tree care needs and provides the highest quality service.
