Firefighters responded to the home around 11:54 a.m.
The fire was located in the basement, on the exterior, and in the first floor wall. Electrical service to the home was involved in the fire, which limited firefighting efforts temporarily.
Fire officials said Eversource was able to shut off power to a section of town remotely within a minute or two of the request by the Fire Department.
Residents in the effected area were inconvenienced without power for 30 minutes. Once the home was isolated from the power system, Eversource remotely turned the power back on.
