Tree Safety Audits (Education/Commercial)

Tree Safety Audits (Education/Commercial)

Lizzie the Arborist provides independent Tree Safety Audit Inspections for educational (schools and daycares) and commercial (businesses, strata, real estates) properties.

Our arborist reports are clear, concise and stick to the scope of work. We methodically investigate any areas of concern and document all findings into a risk assessment that rates risk as High, Medium, or Low which allows us to provide recommendations to mitigate any tree defects and health concerns. Trees are also providing a works priority rating to allow you to prioritize future tree works.

Call us on 0401 301 233 for a confidential discussion about your tree audit requirements.
