Healthy trees add beauty, shade, and value to your property — but when they show signs of stress, pests, or disease, early action is key. At West Coast Tree Service by TimberTEKS, our ISA-certified arborists provide professional tree diagnosis services in Vancouver WA, Portland OR, and surrounding areas to identify problems and create effective treatment plans.
🕑 Why Tree Diagnosis Matters
Just like people, trees need check-ups. Ignoring warning signs can lead to costly damage or even removal. A professional tree diagnosis can:
- Identify diseases before they spread
- Detect pest infestations such as beetles, borers, or mites
- Assess structural weaknesses that pose safety risks
- Recommend proper care, pruning, or treatment to restore health
- Help you protect your investment in landscaping and property value
⚠️ Signs Your Tree Needs Diagnosis
Call our arborists if you notice:
- Yellowing or browning leaves out of season
- Dead or dropping branches
- Fungus or mushrooms growing near the base
- Holes in the trunk or branches (insects)
- Cracks, splitting, or hollow sections
- Leaning or root lifting
- Sudden canopy thinning
These issues may point to disease, pest infestations, or structural problems.
