Tree Trimming Assistance

Large trees and branches can cause extended power outages when they come in contact with overhead power lines. While ComEd has an extensive maintenance program in place which helps keep lines clear for distribution and transmission rights of way, we understand there may still be a need for further assistance. Find options for tree trimming near service wires or between poles on or near your property.

For your safety, do not climb trees or trim trees that are located near power lines without taking necessary precautions first. Hiring a qualified contractor is a safer alternative. Always keep children away from trees that are near power lines. Even momentary contact with a power line, or a tree or branch that is in contact with a power line, can severely injure or kill. Contact ComEd for further assistance.

Service Wire

Lines to house 

ComEd does not perform non-emergency tree trimming for the wire running directly to customers' meters (the service wire). If you hire a contractor, or plan to do any trimming on your own, ComEd will either drop or de-energize your service wire and will re-connect it once trimming is complete. Your home will be without power until your service line is re-connected. There is no charge for this service.

Please call us at 1-800-EDISON-1 (1-800-334-7661) and a ComEd representative will contact you as soon as possible to schedule the date and time of the service wire drop.

Between Utility Poles 

Several options are available for trees that are near power lines between utility poles located on your property.

Line Clearance by ComEd

ComEd's qualified line clearance tree trimmers can provide clearance around primary and secondary lines so that a private contractor can safely trim or remove the rest of your tree. Please contact us to get more information about this service and a written estimate for the work.

Line Maintenance Investigation

ComEd will, in certain cases, stop the electricity flowing through the power lines near the tree(s) in question, allowing a private contractor to work around de-energized lines. Please contact ComEd at 1-800-EDISON-1 (1-800-334-7661) and request a "line maintenance investigation" (LMI) to see if this is an option for you. There is no charge for this inquiry.

Private Contractor

You may also consult a non-ComEd tree contractor that employs line clearance qualified tree trimmers (in accordance with industry safety requirements found in the current version of ANSI Z133.1) to trim or remove your tree. You are responsible for all costs associated with this option. You may contact ComEd at 1-800-EDISON-1 (1-800-334-7661) should you have additional questions about these options.
