Arborist Services
Professional Arborist
When you need a qualified arborist, Armstrong Tree Service brings the training, the diagnostic skill, and the scientific knowledge to assess your trees’ health and provide professional care recommendations. Trees can’t tell you when something is wrong. By the time a tree shows visible distress—yellowing needles, thinning canopy, fungal growth—the underlying problem has often been developing for years. Is the tree sick, stressed, or simply aging? Can it be treated, or does it need removal? Is it a hazard, or a healthy tree with a cosmetic issue? Answering these questions requires more than experience with a chainsaw. It requires the diagnostic training of a professional arborist—someone who understands tree biology, pathology, and the specific pests, diseases, and environmental stresses affecting trees in the Sierra Nevada. Our arborist provides professional tree assessments based on the science of arboriculture, giving you accurate information for sound decisions. For the highest level of certification, our Certified Arborist service provides ISA-certified expertise. For tree work following arborist recommendations, our Tree Service provides comprehensive solutions.
What Our Arborist Provides
Tree Health Assessment and Diagnosis
When you’re concerned about a tree—unusual symptoms, storm damage, construction impacts, or general decline—our arborist performs a systematic evaluation from roots to crown. The root zone is checked for compaction, grade changes, trenching damage, and fungal growth indicating decay. The trunk is inspected for cracks, cavities, cankers, fungal conks, and bark abnormalities. The canopy is evaluated for branch dieback, foliage density, pest activity, and structural defects. The tree’s overall condition is assessed in the context of its species, age, site conditions, and Sierra Nevada environmental stresses. The result is a clear explanation of what’s happening and what your options are—treatment, monitoring, pruning, or removal.
Pest and Disease Identification
Sierra trees face pressure from insects and diseases that can kill a mature tree with alarming speed. Bark beetles have devastated forests throughout the region and don’t distinguish between national forest and your backyard. Dwarf mistletoe weakens conifers and increases beetle vulnerability. Root diseases can topple apparently healthy trees without warning. Our arborist identifies these pests and diseases, assesses the extent of infestation, and recommends appropriate treatment. When treatment can save the tree, we’ll tell you. When removal is necessary to prevent spread, our Tree Removal and Hazard Tree Removal services handle the job safely.
Why Professional Arborist Assessment Matters
Making decisions about your trees without professional assessment risks two costly mistakes. The first is removing a tree that could have been saved. Many alarming symptoms—sap flow, bark splitting, needle drop—are normal stress responses. Professional assessment distinguishes between genuine decline and temporary stress from drought, construction, or weather. The second mistake is keeping a tree that should be removed. Advanced root decay, severe beetle infestation, or critical structural defects may not be obvious to an untrained eye while posing imminent risk. By the time symptoms are visible to a property owner, the tree may already be beyond saving and dangerous to keep. Professional arborist assessment gives you accurate information for the right decision. For trees needing removal, our Tree Removal service handles the job. For the most challenging situations, our Crane Tree Removal service provides heavy-lift capability. For stump grinding, our Stump Grinding service eliminates what remains.
Arborist Services for Property Planning
Arborist assessment isn’t only for troubled trees—it’s essential for property planning and development. Before building an addition, installing a driveway, excavating for utilities, or undertaking major landscaping, an arborist can identify which trees should be preserved, which will likely decline from construction impacts, and which should be removed before work begins. Construction damage is a leading cause of tree death on developed properties. Root cutting, soil compaction, grade changes, and trunk wounds all cause damage that may not become visible for years. Identifying vulnerable trees and establishing protection zones prevents these losses. For trees requiring removal for construction, our Tree Removal service handles the work. For lot clearing, our Lot Clearing service prepares building sites. For defensible space planning, our Defensible Space and Fuels Reduction services address fire safety. For firewood from removed trees, our Firewood service processes usable timber. For winter access, our Snow Removal service manages seasonal conditions.

Frequently Asked Questions About Arborist Services
What does an arborist do?
An arborist is a professional trained in the science of tree care. Our arborist performs health assessments, diagnoses pest and disease problems, evaluates tree risk, and provides professional recommendations.
What’s the difference between an arborist and a tree trimmer?
A tree trimmer cuts branches. An arborist understands tree biology, diagnoses health problems, and makes science-based recommendations. Our arborist provides assessment; our Tree Trimming service handles the cutting.
When should I call an arborist?
Call when a tree shows unusual symptoms—yellowing, thinning, dieback, fungal growth—or when you need professional opinion about tree health, safety, or management. Also call before construction that may impact trees.
How much does an arborist consultation cost?
Costs vary based on the number of trees and assessment complexity. We provide upfront pricing. Professional assessment often saves money by preventing unnecessary work or identifying problems early.
Can an arborist tell me if my tree is dangerous?
Yes. Tree risk assessment is a core arborist function. We evaluate failure likelihood and potential consequences, providing clear risk ratings and recommendations.
What tree problems are common in the Tahoe area?
Bark beetles, dwarf mistletoe, root diseases, snow load damage, drought stress, and construction damage are the most common issues.
Do you have a certified arborist?
Yes. Our Certified Arborist service provides ISA-certified expertise—the highest professional arborist credential.
Will an arborist tell me to remove trees I don’t need to remove?
No. We provide honest assessment without sales pressure. If your tree is healthy and can be preserved, that’s what we recommend.
