Every year, hundreds of people are seriously injured or killed by contact with electrical lines. All wires should be considered dangerous. If you have electrical wires in or near your trees, please have a qualified professional do the pruning, or contact us. We may do your pruning for you if there is a potential for contact with high voltage lines. High voltage lines can cause injury if you touch a tree that is in contact with the lines, or are in contact with a branch that falls onto the lines. So please be careful, and if in doubt give us a call at 763-441-2020. We'd be happy to come out and assess the situation.
