Fire crews were called to a Leyland home after a blaze broke out in a bedroom.
Firefighters from Leyland and Bamber Bridge were called to Hampden Road at about 3.20pm on Sunday.
It is believed the fire was caused by a cigarette, which set fire to clothing in a bedroom.
The bedroom was damaged by smoke and heat, but nobody was injured.
The fire had been extinguished before crews arrived, but firefighters used a hose reel on the smouldering clothing.
