HOLLIS, Maine — Firefighters braved subzero temperatures to battle an early morning fire that destroyed a home in Hollis Monday.

The fire at 34 Hollis Road started around 1:30 a.m., according to Sanford Communication. Seven people who were home when the fire broke out made it out safely.

Crews fought the blaze for several hours in temperatures that reached 15 below zero. Officials said the bitter cold made the fire difficult to fight.

The crews had to tear down the house.

Investigators from the state fire marshal’s office are still trying to determine the cause of the blaze but said it doesn’t look suspicious.

American Red Cross officials said they’ve been in touch with the people who lived there and they’re working with them to help them meet their immediate needs.
