Geography shapes the emergencies here. Inland, a fallen limb can rip the service drop off a house and bend or break the mast it was attached to. On the shore and the islands, flood water and spray are the bigger risk: the January 2024 storms pushed the tide at Portland to a record 14.57 feet and flooded shorelines across Cumberland County, and salt left on a meter socket or in an outdoor disconnect corrodes the connections over the following months until they overheat. Either way, the line between the utility and the homeowner matters. Central Maine Power owns the wires to the point of attachment on the house; the mast, weatherhead, meter socket and panel are the owner's, and a licensed electrician has to repair them before CMP reconnects.
If a wire is down, keep everyone well away and call Central Maine Power or 911, because a line on the ground can still be energized. If water has reached your panel or outlets, do not touch them; turn off the main only if you can reach it from dry ground, and have the equipment inspected before power is restored. Goodnow Electric provides emergency service 24 hours a day and coordinates the reconnect with CMP once repairs are done. On the islands, a damaged mast or meter can mean a longer wait for the utility to return, so getting the owner's side of the repair done promptly keeps your house from sitting at the back of the queue.
Inside the house, call right away for an outlet or cover plate that is hot or discolored, sparking or buzzing from the panel, a burning smell, lights that dim sharply when a motor starts, or a main breaker that will not reset. In Yarmouth's many 1960s and 1970s homes, those symptoms often come from aging breakers, overloaded circuits or failing aluminum connections, and in the oldest houses from knob-and-tube wiring buried under later work. A fast diagnosis makes the circuit safe the same night, and a written estimate follows for any permanent repair.
