The cause of a house fire in the Masonville area late Tuesday night remains under investigation.

Emergency crews responded to a call at 510 Ambelside Drive near Fanshawe Park Rd. and Wonderland Rd. just before 10 p.m.

It’s believed to have started in the basement, but the flames traveled through the walls, resulting in some damage to the first floor as well.

“It was a stubborn fire,” said London Fire Inspector Brent Smith. “We were on scene for quite some time, and we remained on scene all night to ensure that we didn’t have anything rekindle or have any extention damage.”

Everyone inside the house made it out safely.

“The homeowner was the only one home at the time, with a dog, and they got out safely due to the working smoke alarms, thankfully,” Smith added.

The cause is not considered suspicious, although investigators are still trying to figure out how the fire started.

Smith believes the damage estimate will exceed $250,000.

Investigators will be at the scene Wednesday to continue investigating the cause of the fire.
