The company handles storm-damaged and hazardous tree removals, full extraction operations and careful site management to minimise disruption and protect surrounding property.
Safety-focused assessments guide choice of rigging and equipment; trained crews follow industry protocols so removals are controlled, efficient and minimise risk to people and structures.
Removal is recommended for trees that are structurally unstable, heavily diseased or infested, or located too close to homes or power lines.
When these conditions are present, consult Dunbar for a professional assessment and recommended next steps.
Professional trimming promotes tree health, improves appearance and can prevent larger, costlier problems later.

ISA-certified arborists apply best-practice pruning timed to species growth cycles, reducing risk and supporting long-term tree stability and lifespan.
Most pruning is best done in the dormant season (late fall through early spring) to reduce stress and disease risk, though species-specific timing should be confirmed with an arborist.
Dunbar provides 24/7 emergency response for fallen trees, storm damage and other urgent hazards, using established safety procedures to protect people and property quickly.
Typical emergencies include fallen trees, storm-damaged trees and trees at imminent risk of failure; prompt action reduces further damage and safety risk.

Dunbar grinds stumps to allow regrading or planting, removes mulch and debris, and prepares the site for future landscaping using purpose-built equipment.
Professional stump grinding removes trip hazards, prevents regrowth and ensures debris is cleared safely and efficiently by trained crews.
They use specialised grinders to reduce stumps to mulch, remove or redistribute the material as requested, and leave the area ready for landscaping while following safety protocols.
Look for ISA certification, proof of insurance (liability and workers’ comp), and positive customer references.
Have a professional assessment at least annually; higher-risk or fast-growing trees may need more frequent checks.
Contact a certified arborist for diagnosis and prompt treatment recommendations to limit spread.
Yes — pruning improves air circulation and light, supporting healthier growth, resilience and urban ecosystem benefits.
Stump grinding reduces the stump below ground level to mulch; duration depends on size but typically takes a few hours including cleanup.
Clear obstacles, provide crew access, notify neighbours if needed, and discuss specific concerns with the provider beforehand.
An ISA-certified arborist will inspect trees, outline issues and options, provide cost and timeline estimates, and answer questions.
