A sick tree near your home is not a job to put off. Trees Down Under, a local Hills District crew with certified arborists and its own cranes, handles the whole job: inspection, council permits, safe removal and clean-up. As a trusted tree removal company, we’re backed by 20+ years of local experience and 24/7 emergency service.
Disease weakens the trunk, roots and branches from the inside, and the damage often shows only once the tree is close to failing. Large limbs can drop without warning, and an unstable trunk can come down in wind or rain.
A failing tree can injure people, damage the house, fences and vehicles, and bring down power lines. Some diseases also spread to nearby trees. Once a hazard is known, you carry the responsibility for any harm or damage it causes to neighbours.
A professional assessment will confirm whether the tree can be managed or needs to come down. The signs below are the ones to watch for.
Four visible signs often mean a tree needs an arborist’s eye. Any one of them is reason enough to book an inspection.
Branches that snap at a touch, carry no leaves in season or drop bark can point to decay inside the tree. Large dead limbs can fall without warning.
Mushrooms, brackets or soft, crumbling timber near the roots often signal rot you cannot see from the outside.
Deep splits, hollow sections, lifting soil around the roots or a lean that is getting worse suggest the tree’s structure is failing.
Sparse foliage, bare patches or leaves that are small, discoloured or dying back can mean the tree is under stress or infected.
If you spot any of these, get the tree inspected before any removal or major pruning, as council rules may apply.
Every diseased tree job follows the same order: inspection, approvals, removal, then clean-up. Certified arborists run each stage, so you always know what happens next.
An arborist visits the property, checks the trunk, roots and canopy, and confirms whether disease is the cause. If the tree can be saved, the advice says so. If not, the team explains why and what removal involves.
Where approval is needed, the team guides you through the application and arborist report before any cutting starts. The plan then matches the site: sectional dismantling in tight yards, or crane-assisted removal where access is difficult or the tree is large.
A diseased trunk can shift, split or snap without warning, so the plan has to come before the saw. Every cut is sequenced for the people and property below.

The crew clears timber and green waste, and can add stump grinding if you want the ground levelled and ready for replanting.
Often, yes. Under The Hills Shire Council tree regulations, some trees in Baulkham Hills need approval before removal or major pruning. Whether yours does depends on the species, the trunk size, and whether the property sits in a heritage or conservation area.
Removing a protected tree without approval can lead to penalties, even when the tree is diseased. The NSW legislation website sets out the wider framework that council policies follow.
Trees Down Under’s arborists can look at the tree, advise whether approval is likely to be required, and prepare the arborist report where council asks for one. A tree that is already a hazard can be assessed through the 24/7 emergency service.
Trees Down Under also handles the work that often goes with a diseased tree removal, so most jobs can be sorted in one visit.
Tree risk assessments and arborist advice for trees you are unsure about. Tree pruning, including tree trimming of dangerous or overgrown branches. Stump grinding and removal once the tree is down.
