Does cabling always prevent tree removal?

No. Its usefulness depends on the tree’s health, the structural defect, and the people or property exposed. An on-site assessment is needed.

What is the difference between dynamic and static cabling?

A dynamic system allows movement while limiting the separation of branches. A static system provides more rigid support in some cases.

Does cabling need to be inspected after installation?

Yes. Tree growth, equipment wear, and storms can affect the system’s tension or effectiveness.

Can cabling be combined with pruning?

Targeted pruning can sometimes reduce the load on a branch. A professional can determine whether this combination suits the tree.

Tree cabling in Mirabel and the Laurentians

A weak union or heavy branch does not always mean a tree must be removed. An arboricultural assessment can determine whether a support system is suitable for the tree’s structure and observed risk.

Understanding the work

Dynamic cabling allows a tree some flexibility, while a static system restricts movement more. The choice depends on the observed defect and requires an on-site assessment.

When should I request an assessment?

Two co-dominant stems forming a tight union with included bark.
A crack or sign of separation at a main branch union.
A heavy main branch above a frequently used area.
A mature tree of value for which preservation options should be considered.

Methods and equipment

Assess the tree and exposed targets before installation.

Install a dynamic or static system according to the assessment.

Inspect the system periodically and adjust it as needed.

When should the work be scheduled?

Timing depends on the tree’s condition and the risk. A developing defect or hazardous branch should be assessed without waiting for a particular season.

What affects the cost

An estimate depends on the actual job. Here are details to provide:

The height of the tree and number of anchor points.
The type of system and complexity of the tree’s structure.
Access to the canopy and any related pruning work.
The planned inspection and maintenance program.

Before work near power lines

Safety first: are branches near electrical lines?

Never touch the tree or wires. Choose the type of line to see what to do. If you cannot identify it with confidence, keep your distance and contact Hydro-Québec.

If a wire is down, sparks are visible, or there is immediate danger, move at least 10 metres away and call 911.
