"There was not a lot of serious structural damage, it's all repairable stuff. We had a good, quick response and it was a good save."
Mr Robinson said there had been two Carterton crews at the scene for about two hours, with a back-up crew from Greytown. Masterton firefighters supplied thermal imaging equipment to check for "hotspots" hidden from view in walls and ceilings.
Sebastain McEntee said he had bolted from the home after the smoke alarms sounded and he saw heavy smoke and fire near the laundry in the house.
"I was just about to go to sleep when the alarms started going off. I saw the smoke and big flames - a lot of flames - so I ran out and rang for help."
His father, Shayne McEntee, said he, his wife, and their two young daughters were out for the evening and Sebastain had been home alone and watching television.
"From what the fire investigator told us, it was the dryer that caused the fire - a broken belt - the motor probably seized and there was enough heat to spark a flame."
Mr McEntee, who works as a dairy farmer, said he was called and told of the blaze about 9.30pm and, after arriving home, saw plumes of smoke billowing from windows that had been opened in the upstairs rooms.
He said the couple had full fire insurance and he agreed with Mr Robinson the smoke alarms had raised enough of an early warning to help curtail the spread of fire, and likely saved his son's life.
"If it had been half an hour later, he would have been sound asleep and he's a heavy sleeper. Without those alarms, he might have gone to sleep and never woken up again," he said.
"The alarms were crucial. I recommend them to everybody."
Mr McEntee also praised the volunteer Carterton firefighters for "an excellent job" in saving the home, where he and his family had been living since June last year.
He said the family had already planned as part of his work to shift from the Belvedere Rd property to a rural home next week, and they would stay in temporary accommodation in the meantime.
