Fire officials are investigating after a home in Wellesley was heavily damaged by an early-morning fire.

Officials were called to the home on Parkview Drive around 5:30 a.m. on Friday for reports of a vehicle fire inside a garage.

A neighbour told CTV he spotted smoke coming from the garage and called 911.

Another neighbour banged on the door to wake the residents inside.

"Neighbours knocked on the door and when they saw the flames, called 911 and then safely got the family out," says Wellesley Fire Chief Paul Redman.

Neighbour Kyle Walden says he and another neighbour were in the right place at the right time.

"Fortunately we came by when we did because the fire started in the garage, the smoke detectors hadn’t gone off yet," he explains. "They were still sleeping when we knocked on the door."

By the time the three stations arrived, the fire had spread into the entire home, with flames coming out of the roof.

Officials say no one was injured. The home was completely destroyed.

Early estimates pegged the damage at around $500,000, but the fire chief has since increased that to between $600,000 and $700,000.

Redman says that the cause of the fire has been deemed electrical from the vehicle and is not suspicious.
