James Cairnes: Climbing to the Top

By James Florence, Diamond Certified Resource Reporter

SAN ANSELMO — For James Cairnes, an adolescent injury became an unlikely catalyst for a lifelong career in an unfamiliar field. “I was in a motorcycle accident when I was 17 and ended up in the hospital,” he remembers. “The guy in the bed next to me was an arborist. I had no idea what an arborist was, so he told me all about it. I found it fascinating, and when I started college the following year, I enrolled in a three-year arboriculture program. It was sort of by chance, but it ended up significantly altering the course of my life.”

Today, as owner of World Tree Service, Inc., James says his favorite part of his job is going out on a limb for his customers. “I still like climbing, which is something I’ve enjoyed since I started. I also like looking after the long-term health of my customers’ trees and making sure they can exist in harmony with the surrounding wildlife and environment.”

James took a circuitous route to get to his current residence in Marin County—he lived in Norway, Ireland and England before he reached adulthood, and when he was 25 years old, he took a trip to the United States that eventually turned into a permanent residence. “After living in New York for seven years, I was ready to head back to England, but first I went on a cross-country motorcycle trip to California,” he explains. “Soon after I arrived, I met a woman named Natalie Carey, with whom I would later co-found World Tree Service.”

Outside of work, James spends his time engaged in a variety of active outdoor pastimes. “My main sport is motorcycle trials, which basically consists of riding through obstacle courses of logs and rocks without putting your feet down,” he says. “I also like mountain and road biking, as well as surfing.” In keeping with his love of tree climbing, James also volunteers as a climber for WildCare, a wildlife rehabilitation center in San Rafael. “We rescue baby birds that have fallen out of their nests, climb up the tree and reunite them with their parents. I actually met my girlfriend doing this, since she works for WildCare.”

When asked the first thing he’d do if he were to retire tomorrow, James says he’d set out for his longest ride yet. “I would ride my motorcycle to South America. I’ve done a few trips to Central America, so I’ve sort of been building up to this bigger excursion. While I’m down there, I’d like to do some rainforest tree-climbing work, like setting up tree platforms for documentary film crews.”

Ask Me Anything!

Q: What’s your favorite kind of tree?
A: I really like the California buckeye and the dawn redwood, which is unique in that it’s a deciduous conifer.

Q: What’s your favorite thing to do on a rainy day?
A: Read a book by the fire.

Q: What’s your favorite book?
A: “Jupiter’s Travels” by Ted Simon, a British guy who traveled around the world on an old Triumph motorcycle. It was really influential in terms of my own motorcycle travels.

Q: Who’s the best James Bond?
A: Sean Connery.

Q: What’s the most death-defying feat you’ve ever attempted?
A: Bungee jumping at the Pipeline in New Zealand—a 335-foot jump!

What To Ask In Person
Important Questions for Consultations with Local Tree Services

After your phone interviews of tree services in Marin County, meet in person with representatives from the tree care companies you are considering.

Tree care companies serving Novato, Sausalito, Corte Madera and other areas of Marin County should have very specialized equipment to handle all your tree care needs.

They will be able to provide services such as repairing tree damage from storms, as well as view restoration by eliminating tree overgrowth. Be sure to inform them exactly what you want accomplished from a tree service. Make sure you take notes of the ISA certified arborist's / tree trimmer's answers to your questions.

This is particularly true if you have more complex tree care needs. Let the tree service know whether you plan to use an arborist in the long term. Whether you are a potential customer for a tree service, they should get to know your individual tree care needs so they can recommend the best services.

Questions to ask tree care services in person:

  • What kind of tree care equipment do you use?
  • Do you use tree spikes or lifts to climb trees (spikes may harm trees)?
  • How knowledgeable are your employees with working around electrical and other hazardous wiring?
  • Is clean up included? Of what does your tree clean up consist and when will you complete the clean up work?
  • Will I be supplying the water for you to provide tree services (potential hidden cost  otherwise)?
  • How long do you estimate my tree care services will take until completion?
  • After my tree removal, will you also grind the stump? Is there an additional cost for stump grinding service?
  • Do you provide tree storm damage removal or wind damage repair to trees in Marin County?

  • What To Ask References
    Questions for Interviewing References of a Marin County Tree Service

    It’s best to chose a Diamond Certified tree care service because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a tree care service in Marin County, you can have confidence choosing a Diamond Certified company.

    Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified tree care service company within reach, you’ll have to do your research carefully. If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you references of only customers they know were satisfied. If you do, it’s wise to call some references provided by your tree care service.

    Keep in mind, though, that references provided to you by the Tree Care Company are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process.

    That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are content.

    Here are some questions you can ask tree service references in Marin County:

    • What is your total satisfaction level of the service you received from this tree care company?
    • What tree services were provided for you?
    • What reasons were you satisfied or not satisfied with the tree care services you obtained?
    • Do you think you would call this company again for your tree care in Marin County?
    • Were they friendly and professional throughout your interactions with this tree care company?
    • Did they pressure you into any tree care services you did not want?
    • Did they remove trash and debris before they left?
    • Did they make you aware of special accommodations needed prior to completing their work, such as moving vehicles out of their way?
    • Were they easy to work with while they performed tree care services at your home?
    • Did your final price for tree services reflect the original estimate you were given? Why or why not? Were there any hidden costs that on your final invoice?

    Before deciding on the best tree care service in Marin County for you, it’s important to consider the following questions.

    • Whether you are looking for tree trimming in Tiburon, tree cabling in Mill Valley, tree removal in San Rafael, or tree maintenance in Corte Madera, are you able to communicate your needs with the company?
    • Have any tree services in Marin County pressured you into tree services you do not need?
    • Would a full-service tree care company be preferred to a part-time tree care service? (A full-service company will likely be better trained and equipped.)
    • Is there a tree service in Marin County that expressed they wish to take care of your tree needs long-term with your best interests in mind?
    • Are you only seeking a fix to an isolated tree problem?
    • Have you verified all insurance and liability (specifically tree service liability) as well as licensing, training, ISA certification, and tree care experience?
    • Have you checked with the Contractor's State Licensing Board of California (CSLB)?
    • Are they a Diamond Certified tree service? If they are not Diamond Certified, do they have any complaints against them with the Better Business Bureau?

  • How To Work With
    Hiring the Best Tree Service in Marin County

    Congratulations on selecting the tree service in Marin County. Know that in the long term, good tree care will be an investment in your Marin County home. Make sure you have everything in writing with very detailed descriptions of the tree care work to be performed to help avoid misunderstandings.

    Have them give you a start date and estimated time for completion. Ask if tree services will be completed in a few days or if it will be completed in one day? Have them notify you in advance of any additional costs that were unforeseen in your original estimate.

    Now That You Found a Tree Care Company in Marin County
    You got a written estimate based on the tree services you asked to have completed. Of course, unforeseen problems may come up. Ask for any changes of cost in writing. Let them know that you must agree to the extra costs prior to completing tree services.

    Verification of their insurance and workers' compensation is critical, do not just take their word. You could be held liable for any damages to your home, a neighbor's home, or any injury to tree care workers. Ask if there is an extra charge for travel from a tree service in Corte Madera to complete tree care in San Rafael, for example.

    Sign the contract (if applicable) and do a walk-through with the senior contractor overseeing your tree work before it begins.

    Ways to Make Tree Care Work go Smoother
    Understand there may be extra noise and debris while the tree service completes your work. Make sure not to get close while they are completing the work, as this could be a safety hazard.

    Ask your tree care professional what is a safe distance to keep from the work being completed.

    Only talk to tree care workers and tree trimmers when they are safely on the ground.

    It is important to keep any pets out of the way of tree care work and to keep your windows and doors closed as much as possible. This will help avoid dust and debris from tree work getting inside your home.

  • Be a Good Customer
    How Can You Be a Good Marin County Tree Service Customer?

    It's the tree care company's responsibility to put in quality work into tree services using the best possible techniques. You also play a big part in the success of your tree care service. Familiarizing yourself with local laws on tree service contractors will help you.

    Why would you want to be a good customer? Everyone appreciates a pleasant customer. This is no different for tree care in Novato or tree care in Mill Valley.

    Tree care professionals appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship.

    Things may go smoother and any problems may be more easily resolved.

    Here are some simple steps you can take to be a good customer of a professional tree service in Marin County.

    • Be upfront with the tree care service you choose. Let them know what you want from your tree service, and how they can fulfill your expectations.
    • Before you hire a tree service in Marin County, restate to the tree care representative your understanding of the agreement. Most problems with local professional tree services occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
    • When working with your tree care professional, ask if you should call to check on the progress of your tree work.
    • Be sure your contractor has a phone number where they can always reach you while they’re performing tree work in Marin County.
    • When your contractor calls you, always return calls promptly to keep your tree services on schedule.

    • Pay for your tree care work promptly.

    Building a good rapport with your tree care service company will help aid in the process, since communication is crucial to having your specific tree care needs understood. This is especially true if you will need care over the life of your trees. Ideally you will want to use the same company for tree services once you find a good company.

    Whether you need tree pruning in Fairfax or tree fertilization in Almonte, they will get to know your tree needs specifically. This way they can make recommendations for future tree work to keep your home beautiful for years to come.

Written Warranties
Ask for Written Guarantees on Tree Services in Marin County

Some tree services may provide you with a warranty on their tree work.

If you were promised a warranty from the tree services in San Rafael, Novato, or another area of Marin County that you hired, they should be willing to provide you with a written warranty.

What should this written warranty guarantee?

That depends on the tree services you requested and the promises made up front.

If the Marin County tree service planted trees or performed tree pruning and maintenance, they may make guarantees regarding the health of your trees or the longevity of those trees. While no one can guarantee the lifespan of a new tree, most tree services will promise that new trees will live at least a certain length of time or that their services will not cause damage or harm that will shorten the tree's life.

Other guarantees may include tree pest control service guarantees or tree disease treatment warranties.

Regardless of the service, always make sure you understand the terms of any tree service warranty if one is provided.

Top 10 Requests
Top Service Requests for Tree Care Contractors in Marin County

Chances are you know what you need for tree care in Marin County. But if you are new to home ownership, you may be uncertain of what tree services are most common.

Do you know what are the most prevalent tree diseases? Here are some common tree care services and common problems where ISA Certified Arborists can assist:

Bracing and Cabling
 Helps to provide strength to a weak tree with limbs that could break. Without correcting a specific tree weakness, you may risk injury or property damage. This is especially problematic when there are storms.

Dead Branches in Trees
A common tree issue which should be removed to increase tree health. This will also avoid property damage and injury, as dead tree branches are more susceptible to storm damage. You don't want a dead tree limb or branch to fall on a car or break a house window.

Diseases in Trees / Tree Disease Treatment
Often times tree disease is the result of a deficiency of nutrition in trees. Tree disease can range from leaf discoloration, to excess bark peeling, to insect infestations.

Leaning Tree Repair
Your tall tree leans at a noticeable angle. This could be a hazard if there are strong winds during storms. Leaning trees should be corrected by a professional tree service to avoid property damage or personal injuries.

Mushroom Or Fungus Growth
This can happen around the base of the tree, which is a sign of tree decay. There is rotting wood in roots of trees, which means your tree is dying. A well trained arborist can assess your tree and recommend a solution.

Preventative Tree Care
Trees need adequate light, pruning, and food to help it achieve a pleasing tree shape and to live longer. This includes tree fertilizers, which will increase the health and nutrition of your trees. There are both organic and conventional fertilizers that your Marin County Tree Service can provide.

Raised Earth Around Base Of Tree
This can mean your tree is beginning to uproot from the ground. This could be dangerous if a strong storm came through and uprooted your tree. Many of us have seen photos of a tree that crashed on a vehicle or a tree that fell on a house. It is not something you want to see happen.

Solar Enhancement
Solar Enhancement completed by professional arborists in Marin County will ensure there is sufficient light for solar panels to function adequately. If your home has solar panels in San Rafael, you will see improved solar functionality by reducing the amount of shade from trees.

Tree Planting
Perhaps you wish to plant apple trees, or maybe you wish to plant citrus trees. Either way, consulting a professional tree service will assist you with tree planting in San Rafael or Novato.

View Restoration
This can include tree thinning, which creates beautiful filtered views by removing dead wood on trees. They may also perform “windowing” which creates an open space similar to a window's function in your home.

 

Top Products Used By Good Tree Care Services in Marin County?
Your Marin County Tree Care Professional may use a number of products and tools to care for your trees. Here are a few items to expect when receiving tree care services.

Climbing Line or Climbing Rope
These should meet all ANSI safety standards, and will assist a professional arborist with safely climbing trees.

Miracle-Gro
Fertilizer and other products may be used in caring for your trees.

STIHL Professional Chainsaws and Other Professional Tree Trimming Equipment
STIHL professional chainsaws are useful for Marin County Tree Services. They are used to trim trees, clear utility line areas, or for tree shaping and tree pruning.

Electric Pole Chainsaw
These are used as an alternate way for trimming trees. Instead of climbing a ladder to the top of your tree, chainsaw in hand

Rigging Line
Not to be confused with a climbing rope, this assists tree stability by connecting them to stationary objects.

Tree Cabling Tools
Tree cabling is a very specialized tree service, which requires the use of eye lags, extra strength cable, and bracing equipment such as a course threaded rod.

Tree Saver Straps
These should be used when a tree rigging line is put into place. They will help avoid damage to tree bark.

Frequently Asked Questions
FAQ About Tree Care Services

Q: Why Choose a Diamond Certified tree service?

Q: Why Choose a Diamond Certified tree service?
A: Diamond Certified helps you choose a tree service with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only local tree services rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified tree contractor

Q: Why should I commit extra effort into tree care?
A: Trees have long been valued for their aesthetically pleasing qualities, which in turn can increase the value of your home. Trees can increase your home’s worth by up to 25%, depending on placement, health, size of trees, and variety. You should protect your trees with proper tree care services.

Q: Do I really need to water trees?
A: For the most part, trees need to be watered more often when they are young and growing. However, this changes if you are having drought conditions in your area. With normal rainfall levels, the main exception to this would be trees that were not suitable for your local environment.

Q: What does pruning do for trees?
A: It helps your trees stay healthier, especially as young trees grow and mature. It promotes good branch structure, that could otherwise lead to an early death of your tree.

Q: Do arborists prune trees to specific standards?
A: All arborists should follow the “ANSI A300 – part 1 pruning” standard. Ask your tree service if they always use this standard for tree pruning.

Q: What is pruning paint for trees, and is it still needed?
A: This is an out-dated procedure that used to be suggested for sealing cuts on a freshly pruned tree. Research by the US Forest Service has debunked the need for this “wound dressing”, and showed it actually was contrary to the best interests of the trees. You can even harm your trees with too much moisture.

Q: What is the best time of year to prune trees?
A: Most arborists would agree that you can prune most trees at any time it is needed. Although some trees are more likely to need pruning at the turn of different seasons such as summer of fall.

Q: Do I really need to fertilize my trees?
A: Most trees need fertilization at some point in their lives. In the forest, there are natural circumstances such as animal waste, leaves and other plant material falling to the forest floor, and other decomposition that recycles itself. Mulching is one way to help fertilize a tree, but a plant health care program from a certified arborist is best. A certified arborist can make the best determinations based on your local environment and the ground where your trees grow. This will help your trees have the best health.
