A basement fire forced occupants of a Catamount Road home out of the dwelling into the snow early Tuesday, but firefighters prevented the blaze from spreading to the rest of the structure.
Firefighters were dispatched to the scene about 6:30 a.m. Tuesday after residents noticed smoke filling the house.
After determining the blaze had started in a basement utility room, firefighters stretched two hose lines into the basement and doused the flames before the spread.
There was, however, smoke damage throughout the rest of the house, according to firefighters.
No injuries were reported.
The Fire Department's response to the house fire included five engines, a ladder truck and a rescue truck, with a total of 26 firefighters.
Meanwhile, the Fairfield Fire Department provided backup coverage for the rest of town while Westport fire crews were on the Catamount Road scene.
The Fire Marshal's Office is investigating the cause of the fire, but preliminary indications are that it was accidental.
