Crews from Eastham, Orleans, Wellfleet, and Truro responded to a summer home on Great Pond Road around 1:30 PM. Firefighters from Harwich and Dennis provided backup.
After knocking down the fire, crews then had to return to the scene around 1:30 in the morning after the fire reignited, most likely due to an ember and windy conditions.
Eastham Fire Captain William Sprague says the fire is not considered suspicious.
Nobody was injured. The house was unoccupied.
