Belmont Fire Department responded to a two-alarm fire in a multi-story structure on Beech Street early Saturday, Feb. 4, which heavily damaged the top floor.

According to Belmont Fire Chief David DeStefano, first-arriving crews discovered flames coming from the roof of the residential building. Six occupants of the home escaped unharmed from the two-alarm fire.

With the assistance of mutual aid partners from the Arlington, Cambridge, Waltham, and Watertown fire departments, Belmont firefighters brought the fire under control in approximately an hour. Extensive overhaul operations were required to check for hot spots.

“Extreme cold creates additional challenges in fighting a fire, and this fire was no exception,” DeStefano said in a press release. “I wish to commend our firefighters for their terrific work and professionalism in below-zero temperatures and minus-35[F] wind chill, and especially our mutual aid partners for their timely response and support.”
