Tree Risk Assessment Perth
Dickies Tree Service assesses tree condition and risk for residential, commercial and council clients across Perth. Our qualified arborists inspect the tree and its setting, identify the problems that matter, and give you practical recommendations you can act on.
From a single tree that is worrying you to an inventory across a large commercial site, we can help. Our team includes arborists with Certificate III and Diploma qualifications, and we carry $20 million in public liability insurance. Where a formal assessment under a recognised methodology is needed, we have a registered QTRA and VALID assessor on the team.
When you need a tree risk assessment
There are a number of situations where a professional assessment is the sensible first step.
- Commercial duty of care where the public or staff access your property
- Council and development applications involving significant trees
- Insurance claims where a tree has caused damage, or may
- Storm damage follow-up, where structural damage may be hidden
- Boundary disputes needing an objective, qualified opinion
- Ageing trees near buildings, paths, driveways or play areas
What we assess
- Root zoneWe check for decay, soil heave and root severance, all of which affect how well the tree is anchored.
- TrunkThe trunk is examined for cavities, cracks, fungal fruiting bodies and structural defects.
- CanopyScaffold branches and the wider canopy are evaluated for deadwood, weak attachments and weight distribution.
- Site and targetsWe consider soil conditions, local species behaviour, and what could be harmed if the tree or a limb failed.
How we assess a tree
- Qualified inspectionOur arborists inspect the tree and its setting, looking at health, structure and what sits within falling distance of it.
- Findings and recommendationsYou get a clear picture of the condition of the tree and what we recommend doing about it, with anything urgent called out first.
- QTRA and VALID where requiredBoth are recognised methodologies for assessing tree risk. We have a registered assessor on the team and can arrange a formal assessment where one is needed.
Assessments for commercial properties
If you manage a commercial property, school, university, golf course or public space, regular assessments are part of good risk management. Owners and managers have a duty of care to take reasonable steps to prevent harm from trees on their land.
For many of our institutional clients we provide annual assessment schedules and ongoing maintenance contracts that keep their tree stock safe and well managed year-round.
What you get
After the inspection you get our findings and practical recommendations, with anything urgent flagged first. How much detail you need depends on the job, and we will talk that through with you before we start.
Where a formal written report is required for council, an insurer or a body corporate, we can arrange one. Where removal or pruning is recommended, we can quote for that work at the same time.

Common questions
What is a tree risk assessment?
A systematic evaluation of a tree’s health, structure and surroundings by a qualified arborist. The aim is to identify potential hazards and recommend actions to manage any risk to an acceptable level.
What is a QTRA assessment?
QTRA is a recognised method that quantifies the risk of harm from tree failure, producing a rating that can be compared against accepted tolerability thresholds. We have a registered QTRA assessor on the team and can arrange an assessment where one is needed.
How often should trees be assessed?
Annual assessments are a common standard for commercial and public properties. Residential trees in good health may only need assessment every few years, though any sudden change in condition should be looked at promptly.
Do I need an arborist report for council approval in Perth?
Many Perth councils require an arborist report to support applications for removal, significant pruning or development near protected trees. Requirements vary by council, and our team can advise on your situation.
What qualifications should an assessor have?
Look for formal qualifications in arboriculture, public liability insurance, and experience with the species in your area. For a formal risk assessment, look for registration with a recognised method such as QTRA or VALID.
What happens if the assessment identifies a hazard?
Our recommendations carry priority levels. Urgent hazards may need immediate removal or pruning, while lower-priority items might involve deadwood removal or ongoing monitoring.
