When Should You Call a Certified Arborist?

Not every tree issue requires a bucket truck and a hard hat, but some definitely do.

The thing is, many people wait until it’s too late—when the decay sets in, the tree is failing, hazardous, or beyond saving. Knowing when to pick up the phone and call a certified arborist isn’t just about emergencies; it’s about proactive care, long-term health, and risk management. Whether it’s structural concerns, disease diagnosis, or a complex pruning job, there are key signs that call for professional insight.

Let’s break down when it’s time to step in.

Signs Your Tree Needs An Arborist

Spotting these signs early gives you the best chance at saving your tree (and avoiding costly damage). Look out for these:

• Unusual Leaf Discolouration or Early Drop. Healthy trees wear their leaves like a badge of honour. If yours are turning yellow or brown or dropping early—especially in midsummer—it could mean pest issues, disease, drought stress, or nutrient deficiencies.
• Dead or Dying Branches. Brittle, bare, or cracking branches are more than just an eyesore; they’re a safety hazard. Weak limbs are prone to snapping in storms or high winds and should be removed by a professional.
• Cracks or Cavities in the Trunk. Visible splits, holes, or sunken bark often point to internal decay. These structural red flags may not affect the tree today, but they could tomorrow.
• Sudden Leaning or Instability. A once-upright tree that’s starting to tilt may have root damage or soil issues. Don’t wait. Leaning trees are unpredictable.
• Mushrooms or Fungal Growth at the Base. Fungi like mushrooms or shelf-like growths are often a sign of decaying roots or internal rot. Arborists can assess whether it’s cosmetic or critical.
• Visible Pest Infestations. Tunnels in bark, sawdust at the base, or sticky leaves might mean insects like the emerald ash borer, aphids, or spider mites have moved in. And trust us, they won’t leave on their own.
• Bark Peeling or Falling Off. Bark that’s flaking, cracking, or shedding without regrowth may indicate a deeper problem like disease, sunscald, or internal decay.
• Sparse or Thinning Canopy. If your tree’s lost its ability to provide shade, it may be under stress from poor soil, root issues, or infection. Early diagnosis gives it the best shot at recovery.
• Poor Growth or Root Issues. If your tree is stunted or struggling, it could be a root collar issue, soil compaction, or something underground. Arborists know how to investigate and correct it.

Situations Where You Need Emergency Evaluation By An Arborist

Sometimes, calling in a certified arborist isn’t optional. These high-risk or highly technical scenarios need a professional with the right training, tools, and certifications to assess and act safely.

• Storm Damage Assessment. After high winds or heavy snow, an arborist can determine whether a damaged tree is salvageable or needs to be removed for safety.
• Construction Near Trees. Digging or building near trees? Arborists can help protect critical root zones and minimise long-term damage during development.
• Tree Removal & Risk Assessments. Taking down a tree isn’t just about grabbing a chainsaw. Arborists assess risk factors, stability, and legality—especially in regulated areas.
• Pest & Disease Diagnosis. Not all problems are visible at first glance. An arborist can identify pathogens or infestations before they take over.
• Insurance & Legal Reports. Need documentation for a fallen tree, municipal dispute, or neighbour conflict? Certified arborists provide the reports that hold up in official claims.

What Is a Certified Arborist (And Why It Matters)

Just because someone owns a chainsaw and a truck doesn’t mean they’re qualified to care for your trees. When it comes to something as valuable—and potentially hazardous—as a mature tree, you want a certified expert.

A Certified Arborist has passed a rigorous exam through the International Society of Arboriculture (ISA) and has proven knowledge in tree biology, diagnosis, pruning, safety, and long-term care.

So why does that matter to you?

Because trees are living things. They need proper care if they’re going to thrive—not just a quick trim or guesswork diagnosis. A certified arborist knows how to spot issues early, make smart cuts that actually help the tree, and handle tricky situations like storm damage or trees growing a little too close to your roof.

Bottom line: Your trees get expert care, and you get peace of mind.
