Licensed arborists who trim trees the safe way

A Hills District business with local roots

Trees Down Under is a family-run arborist business based in Dural, working across Castle Hill and the Hills District since 2005. Two generations of arboriculture knowledge sit behind every job, from routine tree trimming to larger work on mature trees.

Being local means the team knows the streets, the tree species and the conditions that affect properties in Castle Hill, NSW 2154.

Inspection first, then the safest option

Before any saw is started, a certified arborist looks at the tree and the site. Old, dead or storm-damaged trees can put homes and people at risk if they are handled badly, so the recommendation is always the option that keeps the property safe.

I grew up learning this trade from my father, and that respect for the work never leaves you. Safe work always starts with a proper look at the tree.

Joseph Khoury, Director & Founder, Trees Down Under

Licensed, insured and accountable

The team is fully licensed and insured, and works to the same standard whether the job is a backyard prune or a crane-assisted job. Neighbours across the Hills District can see who is on site and who stands behind the work.

What does tree trimming in Castle Hill include?

Pruning

Pruning removes specific branches to improve a tree’s health and structure. It suits trees with dead wood, crossing limbs or weak growth, and keeps the canopy balanced as the tree matures.

Trimming

Trimming shapes a tree and controls its size. It suits branches growing over roofs, fences or power lines, or blocking light from a garden. Regular tree trimming also keeps overgrown growth from becoming a problem.

Lopping

Lopping cuts back larger limbs, often where branches are heavy, damaged or too close to a structure. It is the heavier end of the work, so the arborist confirms the approach before cutting begins.

Worried about an old or storm-damaged tree?

A dead, ageing or storm-damaged tree can put your home and the people around it at risk. Our certified arborists offer a free tree inspection with no call-out fee, and same-day quoting so you know where you stand quickly. Call 0475 463 597 or request a quote online.

Do I need council approval to trim a tree?

Sometimes, yes. Whether council approval is needed depends on the species, the size of the tree and how much of it is being cut. Some tree trimming needs no permit at all, while larger works or protected trees often do.

It starts with the inspection. A certified arborist looks at the tree, explains what the job involves and says whether approval is likely to apply. A written quote follows, so the scope is clear before anything is booked.

When a permit is needed, Trees Down Under follows the Hills District Tree Management Application process. The team prepares the paperwork and arborist report the council asks for, so owners are not left to work through the forms alone.

Once approved, the crew carries out the job, using crane-assisted removal where access is tight or the tree is large. The site is then cleared, with green waste taken away and the yard left tidy.
