Tree removal often looks easier than it really is. I’ve lost count of how many times I’ve arrived at a Perth property after a homeowner started a tree removal job with the best intentions, only to realise halfway through that things had become far more complicated than expected.
From the ground, a tree can seem straightforward. Cut a few branches, drop the trunk, and clean up afterwards. In reality, every tree carries its own weight distribution, structural weaknesses, and surprises. After more than 25 years working across Perth, from tight suburban blocks in Joondalup to large properties around Gnangara, I’ve seen how quickly a simple job can go pear-shaped.
Before you fire up the chainsaw, it’s worth understanding the risks involved and why professional tree removal often saves far more than money.
Why DIY Tree Removal Goes Wrong Faster Than Most People Expect
Many homeowners assume a tree will fall exactly where they want it to. Unfortunately, trees rarely cooperate.
A Tree Does Not Fall Like a Fence Post
Trees are living structures with uneven weight distribution. One heavy limb can completely change the direction of a fall.
I remember inspecting a large gum tree after a homeowner attempted to remove it himself. The trunk looked relatively straight, but a heavy canopy extended over one side of the property. When the final cut was made, the weight shifted unexpectedly and the tree clipped the corner of a patio roof.
The repair bill ended up costing more than professional removal would have in the first place.
Factors that affect tree movement include:
- Tree lean
- Branch weight
- Wind direction
- Species characteristics
- Previous pruning history
- Root stability
As we often tell clients:
“From the ground, a branch can look light. Once it starts moving, it can behave like a loaded spring.”
Hidden Decay Can Turn a Simple Cut Into a Collapse
One of the biggest dangers is what you cannot see.
A tree may appear healthy from the outside while significant decay is occurring internally. We’ve worked on many Perth trees that looked perfectly sound until the first cut exposed extensive rot inside the trunk.
Warning signs may include:
| Potential Warning Sign | What It Could Mean |
| Large cracks | Structural weakness |
| Fungal growth | Internal decay |
| Dead branches | Tree decline |
| Hollow sounds when tapped | Internal cavities |
| Bark falling away | Stress or disease |
| Sudden lean | Root failure risk |
A tree weakened by decay may collapse before you’re ready for it to fall.
The Biggest Safety Risks of Removing a Tree Yourself
Tree work consistently ranks among the most dangerous trades worldwide.
That’s not because arborists take unnecessary risks. It’s because trees create hazards that change by the second.
Falls From Ladders, Roofs, and Unstable Branches
In Perth, we often see homeowners standing on ladders while reaching out with a chainsaw.
It’s a recipe for disaster.
Professional arborists use:
- Climbing systems
- Safety harnesses
- Rigging ropes
- Elevated Work Platforms (EWPs)
- Controlled anchor points
A ladder may feel stable at first. Add a moving branch, chainsaw vibration, and shifting body weight, and things can unravel quickly.
Quick Safety Checklist
Stop immediately if:
- You need to climb a ladder
- You need to work from a roof
- Branches are above head height
- You cannot maintain three points of contact
- The ground is uneven or slippery
Chainsaw Kickback Can Cause Serious Injury in Seconds
Chainsaws are powerful tools, but they demand respect.
Kickback occurs when the tip of the guide bar contacts wood unexpectedly, causing the saw to lurch backwards.
I’ve seen experienced operators caught out by kickback. For someone using a chainsaw once every few years, the risk is considerably higher.
Common causes include:
- Overhead cutting
- Poor footing
- Fatigue
- Dull chains
- Incorrect cutting angles
Falling Branches Can Bounce, Swing, or Snap Back
Branches rarely drop straight down.
A limb can:
- Swing unexpectedly
- Strike neighbouring branches
- Bounce off the ground
- Roll towards structures
- Snap backwards under tension
Following winter storms across Perth, we often deal with suspended branches known as “widow makers”. These dead limbs can remain lodged in the canopy before falling without warning.
Power Lines Make DIY Tree Removal a No-Go
If power lines are involved, the conversation should end immediately.
One Branch Touching a Line Can Energise the Tree
Many people underestimate how dangerous power lines can be.
A branch does not need to break a line to create a hazard. Contact alone may energise the tree and surrounding ground.
Particular risks include:
- Wind movement
- Wet weather
- Hidden service lines
- Tall gums near boundaries
The consequences can be fatal.
Power Line Work Needs the Right Training and Equipment
Qualified arborists working near power infrastructure require specialised training and equipment.
This may include:
- Low Voltage certification
- High Voltage certification
- Insulated EWPs
- Site-specific risk assessments
- Clearance procedures
This isn’t the sort of work learned from a weekend video tutorial.
Property Damage Can Cost More Than Hiring an Arborist
One mistake can wipe out years of savings.
Roofs, Fences, Retic, Sheds, and Cars Are Usually in the Drop Zone
Many Perth properties present tight access challenges.
Common obstacles include:
- Colorbond fencing
- Reticulation systems
- Limestone retaining walls
- Garden beds
- Pools
- Sheds
- Solar panels
On older suburban blocks, there may be only a few metres between the tree and surrounding structures.
That leaves very little room for error.
Insurance May Not Cover DIY Mistakes
Insurance policies vary significantly.
If DIY work causes damage to your own property or a neighbour’s, coverage may not always apply.
Before starting any removal work, homeowners should carefully review their insurance policy and seek clarification where necessary.
Is DIY Tree Removal Really Cheaper?
At first glance, it often appears cheaper.
The numbers tell a different story.
The Real Cost of Tools, Gear, Tip Fees, and Clean-Up
| Cost Area | DIY Removal | Professional Tree Removal |
| Chainsaw | Purchase required | Included |
| Safety gear | Purchase required | Included |
| Waste disposal | Homeowner responsibility | Usually included |
| Insurance | Personal risk | Covered by contractor |
| Time | Several days | Often completed in hours |
What looks like a budget option can quickly become expensive.
The Cost of Fixing a Failed DIY Job
We’ve been called to jobs where:
- Trees became stuck in neighbouring trees
- Half-cut trunks remained standing
- Branches damaged fences
- Limbs landed on sheds
- Access became blocked
Corrective work often costs significantly more because the site is already compromised.
When Small DIY Tree Work May Be Reasonable
Not every tree task requires a professional crew.
A Simple Ground-Level Prune Is Different From Tree Removal
Basic pruning may be manageable when:
- The work is completed from the ground.
- The tree is small.
- No structures are nearby.
- No power lines are present.
- Proper safety gear is used.
The key is knowing your limits.
Do Not DIY If These Red Flags Are Present
Call a qualified arborist if:
- The tree is leaning
- Branches hang over a roof
- Power lines are nearby
- The trunk has visible decay
- The tree is storm damaged
- A ladder is required
- Council approval may be needed
What a Professional Arborist Does Differently
Professional tree removal is built around planning.
The Job Starts With a Site Assessment, Not a Chainsaw
Before any cutting begins, we assess:
- Species
- Structural condition
- Tree lean
- Access points
- Nearby structures
- Wind conditions
- Waste removal requirements
The assessment often determines whether pruning can solve the issue instead of removal.
Professional Crews Remove Trees in Controlled Sections
Large removals are rarely felled in one piece.
Depending on the site, we may use:
- Rigging systems
- Lowering ropes
- Cranes
- Elevated Work Platforms
- Mechanical lifting equipment
Each section is removed in a controlled manner to minimise risk.
A Qualified Arborist Can Tell You Whether Removal Is Actually Needed
One thing I often tell homeowners is this:
“Just because a tree has a problem doesn’t mean it needs to come down.”
In many cases, a remedial prune, canopy reduction, or deadwood removal can significantly improve safety while preserving the tree.
A good arborist should recommend the solution that suits the tree, not the one that creates the biggest invoice.
Council Rules, Protected Trees, and Perth Property Requirements
Tree removal is not always as simple as making a cut.
Some Trees May Need Approval Before Removal
Requirements vary between local councils and planning areas.
Factors may include:
- Tree species
- Tree size
- Heritage considerations
- Development conditions
- Local planning controls
It’s always worth checking before work begins.
Verge Trees Are Usually Not Yours to Remove
Many homeowners assume verge trees belong to them because they sit outside their property.
In many cases, these trees fall under council management.
Removing or significantly pruning a verge tree without approval can create unnecessary complications.

What to Ask Before Hiring a Tree Removal Company
7 Questions Worth Asking Before You Book
- Will a qualified arborist inspect the tree?
- Are you fully insured?
- Will I receive a written quote?
- How will you protect surrounding structures?
- Is waste removal included?
- Do you offer stump grinding?
- Do I need council approval?
Watch Out for Cheap Quotes That Skip Safety
A quote that looks too good to be true often is.
Low-cost operators may lack:
- Insurance
- Qualifications
- Proper equipment
- Safe work procedures
- Adequate clean-up standards
Tree work is one area where cutting corners can become very expensive.
There’s nothing wrong with tackling a bit of DIY around the house. Painting a fence, planting a tree, or spreading mulch are great weekend projects.
Removing a mature tree is a different kettle of fish.
Tree removal involves height, weight, physics, equipment, property protection, and personal safety. After decades working across Perth properties, I’ve seen firsthand how quickly a seemingly simple job can go wrong.
If there’s any doubt about the size, condition, or location of a tree, getting advice from a qualified arborist is usually the safest and most cost-effective step. A short inspection today could save you from a very expensive lesson tomorrow.
