Before work begins, a qualified crew needs to understand the tree’s condition, the position of nearby wires, the work area, and how branches or trunk sections could move as they are cut. Our tree trimming and pruning work near power lines follows industry clearance standards, and we coordinate with utilities when necessary. The exact plan depends on the site and the line involved. Homeowners should never try to trim, move, or identify a wire themselves.
Why Overhead Lines Change the Work Plan
Overhead lines add an electrical hazard and affect where workers can position themselves, tools, vehicles, and cut branches. A limb that seems easy to remove can shift or swing toward a wire, while a falling tree can pull a line down or leave it under tension. That makes line location part of the work plan from the start, alongside the tree’s structure and nearby homes, roads, fences, and landscaping.
The phrase “overhead utility line” can refer to different wires, including electric power lines and communication lines. Their ownership, electrical status, and clearance requirements may differ, and appearances alone are not a reliable way for a homeowner to determine what a wire carries. A tree care company should not assume a line is harmless because it is lower on a pole or appears insulated — the utility or trained professionals must assess the hazard. OSHA’s line-clearance guidance distinguishes line-clearance work from other tree work and outlines special requirements for workers operating near energized electric lines.
How We Assess the Tree and Work Area
We assess the tree, the wires, and the surrounding site before choosing how to proceed. That includes evaluating tree condition, soil stability, nearby buildings, overhead utilities, sidewalks, and access. Those factors help us determine whether the job is straightforward, needs a different work plan, or should wait for utility coordination.
A site assessment may consider:
- Which parts of the tree are closest to the wires
- Whether branches are touching a line or appear caught around it
- The tree’s lean, cracks, decay, root movement, or storm damage
- Nearby homes, streets, parked vehicles, fences, and walkways
- Where workers and equipment can be positioned without entering a hazardous area
- Whether falling or suspended wood could affect a line
The tree’s condition matters because stable, healthy branches behave differently from storm-broken or decayed limbs. A compromised branch may split unexpectedly, and a leaning tree can shift as weight is removed. For this reason, a plan for a tree near utility wires must account for both the electrical hazard and the way the tree may respond to cutting.
When Utility Coordination Is Needed
Utility coordination is needed when the line’s location, condition, or relationship to the tree creates a hazard that the tree crew cannot address on its own. We coordinate with utilities when necessary, but the need and timing depend on the specific worksite. We may need the utility to identify the line, assess its status, or determine what steps are required before work can proceed.
The applicable electrical safety requirements depend on factors such as the type of work, the line, and the workers’ qualifications. OSHA describes line-clearance tree trimmers as specially trained workers and explains that minimum approach distances vary with electrical conditions. Its electric power standard also clarifies that the standard’s line-clearance provisions have a specific scope. A homeowner should not try to apply a distance or determine whether a crew can safely work around a wire.
Utility coordination does not mean every job follows the same sequence or uses the same equipment. The utility may need to review the site or tell the tree company what conditions must be met before work continues. If the required coordination cannot be completed, we may need to delay or change the work plan.
One example: we handled a diseased pin oak tangled in overhead wires on a tight residential lot in Dormont. Borough coordination took place before cutting began. That kind of site-specific planning matters, though every job does not follow the same process.
How We Plan and Carry Out the Work
We plan the cutting sequence around the tree’s structure, the wire location, and the limits established for the work. When a branch or trunk section could move toward a line, the plan must account for that movement before a cut is made. We may need to revise the approach if the tree is more unstable or entangled than it appeared during the initial assessment.
The right equipment and worker qualifications depend on the site and the electrical hazard. OSHA identifies specific requirements for line-clearance tree-trimming operations, including determining the voltage of lines that may pose a hazard and following the applicable approach distances. These are work requirements for trained personnel, not instructions for homeowners to use when evaluating a crew or attempting the work themselves.
We use specialized equipment for removals involving hazardous trees. Equipment choice for a particular job near wires is confirmed through an on-site assessment and any required utility coordination.
What Homeowners Can Expect During the Job
You can expect us to assess the site, explain the proposed work, and identify any conditions that affect scheduling or access. A job near overhead lines may take additional planning, and utility involvement can affect when work begins. Ask what the estimate includes, whether any utility coordination is needed, and what areas of the property should remain clear.
On workday, the crew may need access to a driveway, yard, or other approved work area. Keep children, pets, and bystanders away from the active site, and follow any directions from the crew about staying clear. If the crew pauses work because a wire or tree condition is different from what was expected, wait for the professionals to explain the next step.
We also provide storm damage cleanup and recovery across Pittsburgh and surrounding communities. Storm-related jobs can involve broken limbs, unstable trees, or other hazards that are harder to evaluate from a distance, so the same careful assessment is important before work proceeds.
Steps to Take if a Tree or Branch Touches a Line
If a tree or branch is touching a power line, stay away and contact the electric utility. Do not touch the tree, branch, wire, or anything that may be in contact with the wire, and do not try to pull or cut the branch free. Penn State Extension advises property owners to call the local utility when a tree or branch affects a utility line and wait for the utility to address the line hazard.
If a line is down, sparking, or creating an immediate danger, treat it as an emergency. Keep people and pets well away and call 911. Then contact the local electric utility to report the hazard. In Duquesne Light’s service area, the utility lists 888-393-7000 for downed wires and other hazardous situations. Elsewhere in the Pittsburgh region, contact the utility serving the address.
Use these precautions:
- Do not approach or handle a downed wire, even if it appears inactive.
- Do not touch a tree, branch, fence, vehicle, or other object that may be contacting a wire.
- Keep children, pets, and neighbors away from the area.
- Call 911 for a downed line or immediate emergency, then report the hazard to the utility.
- Do not resume tree work until the utility or emergency responders say the area is safe.
Penn State Extension also recommends avoiding power lines after storms and contacting the local utility when a tree or branch affects a line. Its storm recovery guidance reinforces that line-related hazards should be left to the utility rather than handled as routine yard cleanup.
Once the utility has addressed the electrical hazard, a tree care professional can assess what remains to be trimmed or removed. For planned work in the Pittsburgh area, homeowners can review our service area and request an estimate.
