Storm tree emergency: what to do first.

Storm-loaded trees are not the same as standing trees. A trunk that is bent, cracked, or leaning after a windstorm stores hidden tension, and a wrong cut releases it in a way that is unpredictable and dangerous. The first job is safety, not removal.

The first ten minutes

• Get everyone clear of the tree and any wires. Treat every downed or sagging line as live, including the service line that feeds your house. Stay back at least the length of a bus and keep children and pets inside.
• Call your hydro provider if a wire is involved. A limb resting on the service line to your house is a power-company job before it is a tree job. In St. Catharines and much of Niagara that means calling Alectra Utilities. No tree crew should cut near an energized wire, and neither should you.
• Photograph everything before anyone moves it. Wide shots of the whole scene, close-ups of the tree, where it snapped, and all the damage it caused. This documentation is the single most useful thing you can do for your insurance claim, and it cannot be recovered once the tree is moved.
• Do not attempt to cut the tree yourself. A storm-loaded tree is under tension you cannot see. That is how a chainsaw afternoon becomes a trip to the hospital. Wait for a licensed, insured arborist.

What counts as an emergency

A tree or large limb on a house, garage, car, or utility line is always an emergency. A cracked or hanging limb still in the canopy, sometimes called a widow-maker, is also an emergency: it comes down on its own schedule, usually the next gust. A whole tree lying in the open yard, having hit nothing, is not an emergency and can be safely scheduled for removal without the cost of after-hours emergency rates.

A reputable tree crew triages by risk. Jobs involving occupied structures and utility lines go first. Jobs involving only property access come next. Open-yard cleanup is scheduled in the calmer window that follows.

Wire safety

Never touch a downed or hanging line, and never assume it is dead. A line on the ground can still carry current, and the zone around it is dangerous well beyond the point of contact. Call the hydro provider, keep everyone back, and wait. Once the line is safe, the tree work is typically straightforward. The emergency is almost always the wire, not the tree.

The widow-maker: hanging limbs in the canopy

A limb that was torn loose but caught in the branches above is called a widow-maker for a reason. It is held up by nothing reliable and will drop without warning when disturbed by wind, another branch shifting, or a crew working nearby. If you see a large broken limb hanging in a tree above an area people use, treat it as an emergency and keep the area clear until a certified arborist can bring it down in a controlled way.

After the danger is gone

Once the hazard is handled, the remaining work, cutting up what fell, clearing the driveway, hauling brush and wood, can move at a reasonable pace. This is also the point at which a written estimate and dated photos become the foundation of your insurance claim.
