Know What You Want
What to Ask Yourself When Looking for Tree Care Companies in Sonoma County

So you know you need tree care services, but do you know what kind of tree company you want to hire?

The types of tree care services offered in Sonoma County may differ. Most tree care companies offer services including insect spraying, tree fertilization, tree removal, stump grinding, cabling and bracing, tree pruning, cavity filling and other tree health and care services. Narrow down the type of tree care services you may need, and seek out companies that perform these services.

Once you’ve done this, ask yourself what kind of business you want providing your home's tree services in Sonoma County.

The following questions will help you get started:

  • Do I want a Diamond Certified tree care company that is rated best in quality and backed by the Diamond Certified Guarantee?
  • Do I want to hire a tree care company in Sonoma County that is well qualified and experienced?
  • If I am unable to use a Diamond Certified tree service, am I willing to do some leg work on my own that could be time consuming (and could save time and money in the long run)?
  • Do I have time to check references, verify licensing, ISA certifications, insurance, and workers' compensation, as well as check for any complaints against the tree trimming company?
  • Have I done my research on the types of tree services commonly performed and what the work entails?
  • Do I have the right budget for securing tree care from an experienced and qualified professional tree care in Sonoma County?

If you are ready to seek out a local tree service, you can chose with confidence by hiring a Diamond Certified tree service.

What To Ask In Person
What to Ask Sonoma County Tree Care Companies in Person?

After your phone interviews of tree care services in Sonoma County, meet with the companies you are considering in person. Tree care companies in Santa Rosa, Windsor, Petaluma, Rohnert Park, Guerneville and other areas should have specialized equipment to handle all your tree care needs.

Local arborists and tree professionals should be able to provide services such as repairing tree damage from storms, as well as view restoration by eliminating tree overgrowth.

Be sure to explain exactly what you want from your tree care contractor. It is also important to take specific notes of a certified arborist's answers to your questions. This is especially true if you have more complicated tree care needs.

Also let them know whether you plan to use their tree services in the long term. Whether you are a potential long-term customer for a tree service in a larger city such as Rohnert Park, Cotati, Petaluma, Santa Rosa, Guerneville or Sebastopol or a smaller town including Occidental, Rio Nido, Roseville or Monte Rio, 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 types of tree care equipment do you use? Do you use tree spikes or lifts to climb trees (spikes may damage living trees)?
  • How experienced are your employees with working around electrical and other potentially dangerous wiring?
  • Is clean up included? Of what does your tree clean up consist? When will you do the clean up work?
  • Will I be providing the water that is used when you provide tree services (a potential hidden cost if they do not provide this)?
  • How long do you estimate my tree care services to take until completion?
  • After you complete tree removal, will you do stump grinding? Is there an additional cost for stump grinding?
  • Do you provide tree services such as storm damage removal or wind damage repair to trees in Sonoma County?
  • After seeing the work I want performed, what is your written estimate and what exactly is included in this price?
  • Will you employ a written contract for my tree care services?
  • What are the terms of your written contract for Tree services in Sonoma County?

  • What To Ask References
    Questions for Tree Care 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 Sonoma 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 company within reach, you’ll have to do some research on your own. 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.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will avoid the possibility that they'll only give you the names of customers they know were satisfied.

    Here are some questions you can ask references of local tree services in Sonoma County:

    • What is your overall satisfaction with the service you received from this tree care company?
    • What tree services did this particular tree company provide at your Sonoma County home?
    • What reasons were you satisfied or not satisfied with their tree care services?
    • Do you think you would call this company again for your tree care in Sonoma 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?
    • Were they easy to work with while they performed tree care services at your home?
    • 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?
    • Did your final cost accurately reflect the original estimate you were given? Why or why not? Were there any hidden costs that appeared on your final invoice?

    Review your choice of tree care services after interviewing several. If you haven't already, now would be a good time to verify tree company information such as contractor licensing, insurance and liability, whether they are an ISA certified arborist, and other certifications.

    Before making your final decision on the best tree care service in Sonoma County for you, it’s important to consider the following questions:

    • Whether you are looking for services such as tree planting and trimming in Santa Rosa, tree cabling in Rohnert Park, tree removal in Windsor, or tree maintenance in Petaluma, ask yourself if you are clearly able to communicate your needs and any of your concerns with the company?
    • Ask yourself if any tree company in Sonoma County is pressuring 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 often be better trained and equipped for your tree service needs.)
    • Is there a tree care company who you felt wanted to take care of your tree care needs long-term with your best interests in mind?
    • If not seeking any long-term tree services, are you only seeking a fix to an isolated tree problem?
    • Have you verified all insurance and liability (including specifically tree service liability) as well as licensing, training, ISA certification, and tree care service experience?
    • Have you checked with the Contractor's State Licensing Board of California (CSLB)?
    • Are they a Diamond Certified tree service?

    If you are confident in the answers to these questions, proceed with making the decision to hire a professional tree service company.

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

    Congratulations on selecting the tree service in Sonoma County that meets your needs. Know that in the long term, proper tree care will be an investment in your home and yard.

    Make sure you have everything in writing, with very detailed descriptions of the tree care work to be performed. Have the tree service you’ve hired give you a start date and estimated time for completion.

    Ask if this will be a multiple day project 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’ve Found Your Tree Care Company in Sonoma 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 extra tree services.

    Additionally, find out if the Sonoma County tree care company offers any written guarantees on their work. If they do, what are the stipulations to the guarantees?

    Be sure the terms of payment for tree services are clearly outlined and agreed upon as well. Once again, ensure the company's insurance liability for tree care work is current and you have verified it yourself.

    Do not just take their word for it, as you could be held liable for any damages to your home, a neighbor's home, or any injury to tree care workers. Sign the contract (if applicable) and do a walk-through with the senior contractor overseeing your tree work before it begins.

    Ways to Make Your Tree Care Job Go More Smoothly
    Understand that with tree care work, there may be extra noise and debris while the tree service company completes your work. Make sure not to get close  to the jobsite while they are completing the work, as this could be a safety hazard. Ask your tree care professional what is a safe distance for you and your family to keep from the work being completed.

    For your safety and theirs, only talk to tree care workers when they are safely on the ground. Do not distract them if they have climbed the tree for pruning or disease inspection.

    It is also important to keep children and pets out of the way of tree care work.

    Keep the windows and doors of your home closed if 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 Sonoma 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 values a pleasant customer. Professional tree services in Sonoma County appreciate customers who are straightforward, honest and easy to work with.

    Your positive customer attitude sets the tone from your end and creates an environment conducive to a good relationship. The tree trimming, tree disease treatment or stump grinding services may very well go smoother and any problems may be more easily resolved.

    Here are a few simple steps you can take to be a good customer when hiring a professional tree service in Sonoma County:

    • Be clear and upfront with the tree care service you choose. Let them know what you want from your tree service, the long-term outcome you desire, and how they can satisfy your expectations.
    • Before you hire a tree service in Sonoma County, reiterate to the company 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 tree care professional, ask if you should call to check on the progress of your tree care.
    • Be sure your service representative has a phone number where they can reach you at all times while they’re performing tree trimming services in Sonoma County.
    • When your contractor contacts you, always return calls promptly to keep the tree services on schedule.
    • Remember that being polite and keeping a friendly smile will go a long way!
    • Pay for all 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. This way, the company you’ve hired will get to know your tree’s specific needs and the tree company can make recommendations for future tree care work to keep your home beautiful for years to come.

Check The Work
Check Tree Care Work Against the Invoice

Always make sure to check that all of the work your tree service company agreed to in the contract was completed as agreed upon and completed to your satisfaction. If they agreed to do all clean up work after providing tree services, make sure your yard was clean.

A complete invoice should include the following:

At minimum it should include the tree maintenance company’s name, address and telephone number, and their license number.

An itemized list of all work performed, and will ideally include specific descriptions of the work done.

An itemized cost with a break-down of both labor and materials cost.

The invoice should also include the start date, an estimated completion date or possibly a guaranteed end date. There may be a clause for certain delays that are excusable such as inclement weather.

Top 10 Requests
Common Sonoma County Tree Service Requests

Chances are you know what exactly what you need completed for your tree care in Sonoma County. However, you may also be new to home ownership and are unsure of what tree care services are commonly performed.

The following are common tree care services and common tree diseases where ISA Certified Arborists and tree care companies in Sonoma County 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.

Removal of 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 Santa Rosa 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 overall health and nutrition of your trees. There are many organic and conventional fertilizers for trees that your Sonoma County Tree Service can provide.

Raised Earth Around Base Of Trees
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 Sonoma County will ensure there is sufficient light for solar panels to function adequately. If your home has solar panels in Santa Rosa, you will see improved solar functionality by reducing the amount of shade from trees.

Tree Planting
If you wish to do some Tree Planting in Santa Rosa or Petaluma, you should consult a professional arborist. You may 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 Sonoma County.

View Restoration
This can include tree thinning, which creates lovely 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.

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.
