Hazardous tree removal
A tree doesn't have to fall to be dangerous. Here's how to spot a high-risk tree and what removing one involves.
A hazardous tree is one that's likely to fail and has something to hit: a house, a car, a sidewalk, a play set or a neighbor's roof. These jobs take more planning than an ordinary removal, because a dead or decayed tree can't be trusted to hold a climber or ropes the way a healthy one can.
Signs a tree may be a hazard
- Dead branches in the crown, or a crown that leafs out thin and late
- A lean that's new or getting worse, with soil heaving on the opposite side
- Cracks in the trunk, or a split where two main stems meet
- Fungus, cavities or soft wood near the base
- Large wounds or broken tops from past storms
- Roots cut by a driveway, sewer line or addition
Dead and dying ash
The Virginia Department of Forestry lists the signs of emerald ash borer: D-shaped exit holes in the bark, thinning in the canopy, sprouts from the trunk, serpentine tunnels under the bark and heavy woodpecker activity in winter. DOF says a healthy ash can die about three years after decline first shows. Trunk injections can protect high-value ash that still has at least 70 percent of its crown alive, so it's worth asking whether a tree is a candidate for treatment before you remove it.
How are hazardous trees removed?
Crews often avoid climbing a badly decayed tree and work from a bucket lift or use a crane instead. They may set up a wider work zone, close part of a driveway, or take the tree in smaller pieces. Hidden problems like internal decay and root damage are hard to judge from the ground, which is why Virginia Cooperative Extension recommends a certified arborist for risky trees.
Don't wait for the next storm
Hazard trees are cheaper and safer to remove on a calm day than after they've dropped onto something. If you're not sure, ask for an assessment.
The tree company prices the job after seeing the tree, what's under it and how equipment can reach it. We don't quote prices, and a number given over the phone without a visit is only a rough starting point.

Common questions
Can an ash tree with emerald ash borer be saved?
Sometimes. The Virginia Department of Forestry says trunk injection works best on ash with at least 70 percent of the crown still alive. Trees in worse shape are usually removed.
Who decides whether a tree is dangerous?
A certified arborist can assess it. Many tree services have one on staff, or you can hire one independently for a second opinion.
