Battling frigid temperatures, firefighters quickly extinguished flames in a crawl space at a Fairfield Avenue home late Tuesday, preventing the fire from causing serious damage to the dwelling.

The fire was reported about 10 p.m. Tuesday when residents smelled smoke in the basement.

Arriving on the scene, firefighters spotted smoke coming from an exterior wall at the front of the house. The blaze had broken out in the crawl space directly below the boiler, firefighters said.

The fire was quickly extinguished, and as a result, structural damage was minimal, according to fire officials. Damage to the first-floor boiler room was also minimal, they said.

Weather conditions were a challenge to fire crews, with the freezing temperature registering a wind-chill value of about zero during the operation.

Three Westport engines, a truck company and a command car were dispatched to the fire scene, while Fairfield firefighters sent an engine company to provide backup coverage in the event of any other incidents.

There were no injuries reported by firefighters or the home's residents, who had to find alternate shelter for the rest of the night.

The cause of the fire remains under investigation.
