FAQS

A tree health assessment involves evaluating the tree’s structure, leaf condition, bark integrity, root health, and overall vitality. Our certified arborists look for signs of stress, disease, pest activity, and environmental damage to recommend the best course of action for long-term health.

 

Signs of disease or decline include wilting leaves, discolored foliage, excessive leaf drop, fungus or mold, bark splitting, or visible pests. If you notice any of these, it’s best to schedule an assessment to prevent the issue from spreading or becoming hazardous.

 

A tree risk assessment identifies structural weaknesses, root instability, and other hazards that could cause a tree to fall or lose limbs. It's especially important for trees near homes, sidewalks, power lines, or in high-traffic areas to prevent property damage or personal injury.

 

Yes. Many trees can be saved with early intervention. We use eco-conscious treatment methods like trunk injections and targeted sprays to combat pests and diseases without harming your soil, pets, or surrounding plants.

 

Absolutely. We use ArborJet and Mauget-certified injection systems that minimize chemical exposure and deliver treatment directly into the tree’s vascular system. This reduces runoff, making it safer for your home and the environment.

 

Certified arborists are trained in tree biology, risk assessment, disease management, and proper care standards. Unlike landscapers, arborists follow ANSI A300 industry protocols and provide expert consultation for long-term tree health and safety.

 

Yes, many HOAs and city planning departments require a formal arborist report for tree removal, risk evaluation, or preservation planning during construction. Our consulting services meet all legal and documentation requirements.

We recommend annual assessments, especially before and after storm seasons. Trees in high-traffic areas or with a history of disease or pruning should be checked more frequently to ensure safety and early issue detection.

Yes. Tree risk assessments can support insurance claims by documenting pre-existing conditions, potential hazards, and professional recommendations. This is often essential after storm damage or liability incidents.
