Dangerous Tree Removal

Arborist Services Pickering Ontario Norway Maple removal

Arborist Services in Pickering. When a mature Norway maple in Pickering starts dropping heavy limbs near your home, it’s not just a nuisance — it’s a warning sign.

That was the situation at a residential property on a quiet street in Pickering, Ontario. The homeowner noticed several large branches had fallen in the front yard. Concerned for their family’s safety, they called in Sarginson’s Tree Services for an expert opinion.

What we found was a textbook case of Verticillium Wilt — a serious tree disease that weakens the internal structure of the tree, often beyond repair.

The Tree: Norway Maple in Decline

Arborist in Pickering Norway Maple in Decline

The tree was a mature Norway maple, a common species planted along streets and suburban front gardens across Pickering. Known for their broad canopy and deep shade, Norway maples can live for decades — but they’re also highly susceptible to soil-borne pathogens like Verticillium Wilt.

When we arrived, the warning signs were clear:

Several upper branches had already broken off without any storm activity

The crown showed thinning leaves on one side.

The bark had begun to split on the lower trunk.

Fungi were visible at the base of the tree — a sign of internal decay.

The situation was no longer just cosmetic. It had become a hazard.

What Is Verticillium Wilt?

Verticillium wilt infects a tree through the roots,

Verticillium Wilt is a disease caused by a fungus in the soil that enters through roots. Once inside, it blocks the flow of water and nutrients, leading to dieback in the canopy and eventual death of the tree. It’s hazardous because:

The decline can be uneven and misleading.

Trees may seem to “recover” one season, then deteriorate rapidly the next.

Infected trees become brittle, increasing the risk of sudden limb drop.

In this case, the homeowner had initially assumed the damage was due to winter stress or insects. But as the limbs continued to fall — one landing just metres from a walkway — they knew it was time to act.

Our Approach: Safe Removal in a Residential Setting

Norway Maple Tree Removal Pickering ontario

Removing a diseased tree in a suburban front yard presents several challenges:

Tight space: We needed to avoid damaging any fences, driveways, and neighbouring gardens.

Pedestrian safety: Our crew coordinated timing to avoid foot traffic.

Tree stability: Because of the disease, traditional climbing methods weren’t safe.

Instead, we used a bucket truck and rigging system to remove the crown section by section. Every cut was lowered carefully with ropes to prevent damage below. The trunk was then safely dismantled, ground-level stumps were removed, and the entire area was cleaned to avoid contamination of nearby plants.

If you live in Pickering — especially in older neighbourhoods with large trees — it’s worth learning how to spot trouble early. Here are some key signs your tree may need attention:

Sudden limb drop without wind

Dead patches or thinning leaves on one side of the crown

Visible fungus at the base

Cracks or splits in the bark.

Sap streaking or discoloration on the trunk

These symptoms don’t always point to Verticillium Wilt, but they do signal stress. Left unchecked, problems like this can escalate fast — especially during summer storms

Why Early Action Matters

Norway maple tree removal job Pickering Ontario

The longer a tree is left to deteriorate, the more difficult (and expensive) it becomes to remove. Diseased trees lose internal stability, making them hazardous to climb and increasing the likelihood of emergency removal, which often incurs additional costs.

Early action also protects your neighbours. Falling branches can easily land on driveways, parked cars, or even passers-by. And under Ontario law, if a tree on your property damages a neighbour’s home due to known issues, you could be liable.
