The second floor of a single family house at 292 Blanchard Rd. in Cumberland was heavily damaged by a fire early Sunday morning.
Cumberland Fire Chief Daniel Small said the fire started in a metal chimney attached to a wood stove at about 1 a.m. The occupants and their cat escaped unharmed.
Small said it took 25 firefighters a half hour to contain the blaze.
One firefighter slipped and fell but was not seriously hurt, Small said.
