Questions to Ask Before Hiring Tree Care Companies in Napa County

You know you need tree work completed, but do you know what type of tree service you want to use?

There are many tree companies out there to choose from, or perhaps someone recently handed you a business card offering tree services. Ask yourself what kind of business you want performing your tree services in Napa County.

The following questions will help you decide what you need from a local arborist or tree care company in Napa County.

  • Do I want a Diamond Certified tree trimming company that is rated best in quality and backed by the Diamond Certified Guarantee?
  • Do I want a professional arborist or tree health service in Napa County that is well qualified and experienced?
  • Have I done sufficient research on tree services and what tree work entails?
  • If I am unable to hire a Diamond Certified tree service, do I have time to conduct research on my own (which could save time and money in the long run)?
  • Do I have a sufficient budget for hiring an experienced and qualified tree service in Napa County?
  • Do I have time to check references, verify licensing, verify ISA certifications, verify liability insurance and workers’ compensation, as well as check for any complaints against the company?

Whether you are in Rutherford, American Canyon, Napa, St. Helena, Deer Park or other rural areas of Napa County, you can choose a Diamond Certified tree service with confidence.

What To Ask In Person
When Choosing a Tree Service in Napa County

After your phone interviews with tree companies, meet in person with the companies you are considering. Tree services should have specialized equipment for all your needs.

They will be able to offer services such as repairing tree storm damage, view restoration, and reducing tree overgrowth. Be sure to communicate exactly what you want from a tree service. Make sure you take notes of the ISA certified arborist’s answers to your questions.

This is especially true if you have a complex tree care problem. Let the tree service know if you will employ an arborist for the long term. Your tree care professional should get to know your tree care needs so they can recommend the best services now and in the future for the health and safety of your trees and property.

Questions to ask local arborists and tree services in person include:

  • What tree care equipment do you use?
  • Do you use tree spikes or lifts to climb trees (remember, spikes may damage trees)?
  • How experienced are your employees with working around hazardous electrical wiring?
  • Is clean up included? When will clean up be completed?
  • Will I supply water for tree services (a potential hidden cost)?
  • How long do you estimate my Tree services will take?
  • After tree removal, will you also do stump grinding? Is there an extra cost for stump grinding service?
  • Do you provide tree storm damage removal or wind damage repair to trees in Napa County?
  • After seeing the tree services I need, what is your estimate?
  • Will you have a written contract for my tree care services?
  • What are the contract terms for tree service in Napa County?

  • What To Ask References
    Questions for Napa County Tree Service References

    It’s best to choose 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 Napa 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 yourself, make sure to ask for a list of the company’s 10 most recent customers. This will help avoid a tree service only giving references of 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 the tree service favor the company, instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

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

    • On a scale of 1 to 10, what is your satisfaction level with this tree service?
    • What Tree services were provided for you?
    • What reasons were you satisfied with these tree services?
    • What reasons (if any) were you unsatisfied with the tree service?
    • Would you call this company again for tree services in Napa County?
    • Were they friendly and professional through all of your encounters?
    • Did they pressure you into tree services you did not want?
    • Did they remove debris before they left?
    • Did they notify you of any accommodations needed before starting tree work (moving vehicles)?
    • Did your final cost reflect the estimate you were given? Why or why not? Were there any hidden costs on your tree service invoice?

  • Review Your Options
    Questions to Ensure You Hire a Good Tree Care Company

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    Review your choice of tree services and make your final selection. If they are not a Diamond Certified tree care company, do they have any complaints with the Contractors State License Board (CSLB)?

    Before deciding on the best tree care service in Napa County, consider these additional questions.

    • Whether seeking tree pruning in Angwin, tree cabling in St. Helena, tree removal in Napa, or tree planting in Deer Park, can you communicate your needs with the company?
    • Has a Napa County tree service pressured you into tree services you do not want?
    • Would a full-service tree service be preferred to a part-time tree service? (A full-service company will likely be better equipped and trained.)
    • Has a tree service in Napa County expressed interest in your long-term tree work needs?
    • Did you feel they have your best interests in mind?
    • Are you only seeking a fix to an isolated tree problem (no long-term tree service)?
    • Have you checked Tree service liability and insurance, as well as licensing, tree care training, ISA certification, and experience?
    • Have you contacted the California Contractor’s State Licensing Board (CSLB)?
    • Are they a Diamond Certified tree service in Napa County?
    • If they are not Diamond Certified, do they have any complaints with the Better Business Bureau or elsewhere?

    If you are confident in the answers to these questions, make your decision to hire a professional tree service company.

  • How To Work With
    Choosing the Best Tree Service in Napa County

    In the long term, good tree care will be an investment in your home.

    Now that you have chosen a good arborist, tree trimmer or tree service, make sure you have everything in writing, including detailed descriptions of the services to be performed.

    This will help avoid misunderstandings. Have your tree trimmer or arborist give you a start date and estimated time for completion. Ask them to notify you in advance of any additional costs that were unforeseen in your original estimate or any changes to the start date or completion date.

    Now That You Have Chosen a Napa County Tree Service
    You received an estimate based on the tree services you asked to have completed. Of course, unforeseen problems may arise.

    Ask for any changes to your cost in writing. Tell them you must agree to any additional costs prior to completing tree services.

    If you haven’t already, ask if there is an extra charge for travel to your home. Sign the contract and do a walk-through with the senior contractor before it begins.

    Once you’ve signed a contract for tree trimming or tree health screening, you and your Napa tree contractor are bound by that contract. For this reason, be sure you understand all terms and have agreed to all specifications in the contract.

    Ways to Make Tree Services Go Smoother
    Even when you’ve hired a good tree company that takes customer service seriously, there may be noise, debris and a few inconveniences while your tree service is being completed.

    There are a few ways you can help the scheduled tree services go more smoothly and easily.

    First, make sure not to get close while the arborists or tree contractors are completing the work, as this could be a safety hazard. Ask your tree care professional what a safe distance is for you, children and pets.

    Only talk to a tree care worker when they are on the ground.

    Keeping your windows and doors closed as much as possible can help limit the amount of dust, pollen or particles that enter your home. You may also want to cover or move outdoor decorations or vehicles that may be in the draft zone if your contractor is cutting, pruning or spraying your trees.

  • Be a Good Customer
    Ways to Be a Good Customer for a Napa County Tree Service

    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.

    Building a good rapport with your tree care service company will help, since communication is crucial to having your specific needs understood. This is especially true if you will need care over the life of your trees.

    Whether you need tree pruning in Napa County, stump grinding, tree straightening or tree fertilization, a good tree contractor 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.

    Here are some simple steps you can take to be a good customer:

    • 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.
    • Restate your understanding of the agreement for tree services. Most problems with professional tree services occur because of a breakdown in communication. By being clear about expectations, you can avoid most conflicts.
    • When working with your tree service in Deer Park or Calistoga, 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 services.
    • When your contractor calls you, always return calls promptly to keep your tree work on schedule.
    • Remember that being polite and keeping a friendly smile will go a long way!
    • Pay for your tree care work promptly.

    Why would you want to be a good customer? Everyone appreciates a pleasant customer. This is no different for tree services. 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.

Top 10 Requests
Napa County Tree Services

If you have owned property with trees, you probably know what type of work you need completed by tree services in Napa County. However, if you are new to home ownership, you may wonder what tree services are commonly performed or available to you.

Here are some common tree care services and common problems where ISA Certified Arborists can assist:

Bracing and Cabling
Helps to provide extra support to strengthen a tree that may be weak and have limbs that may 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 branches are more susceptible to storm damage. You don’t want a dead tree limb or dead tree branch to fall on a car, break a window, or cause other structural damage.

Diseases in Trees
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 proper 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 for trees that your Napa 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 to further uproot your tree. Many of us have seen photos of a tree that crashed on a vehicle or a tree that fell on a house.

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

Tree Planting
Perhaps you wish to plant Ambrosia Pomegranate trees, or maybe you wish to plant citrus trees. Either way, consulting a professional tree service will assist you with tree planting in Napa or American Canyon.

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 additional open space, similar to a window’s function in your home.

 

Common Products for Tree Services in Napa County?
Your Napa County tree care professional may use a number of different products and tools to care for your trees. Here are a few things to expect they may use when performing 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 Tree Fertilizer
Fertilizer and other products from this brand may be used in caring for your trees.

Professional Chainsaws
Professional-grade chainsaws can be used by a Napa County tree service to trim trees, clear utility line areas, or for other 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
This is a very specialized tree service skill, 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 bark while tree work is being performed.

Frequently Asked Questions
FAQ About Tree Care Services

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.
