An investigation is under way to determine the cause of an explosion that leveled a two-story house in Bucks County on Tuesday morning.

Police said the residents of the house in the 4300 block of Biddeford Circle in Buckingham Township were not home when neighbors reported hearing a boom about 9 a.m. No injuries were reported. The house did not catch fire.

”Around 9, I just heard the loudest explosion,” said Pam Wahl, a neighbor.

Police said that there were no gas lines into the house but that a propane tank had been filled earlier in the morning.

Neighbors said the basement in the home had recently been refinished.

”It was absolutely beautiful,” said Diane Clemens, who identified herself as a close friend and neighbor. She had run outside at the time of the explosion and turned to see the home in scraps.

Two parents and their two children lived there, according to neighbors who picked up the phone to call the family and let them know what had happened.

“I think just about every neighbor here was calling them,“ Wahl said.

“She’s a real firecracker,” she said of the mother. “She’s real strong. But she was in shock. Like, being told your house blew up?”

At the time of the explosion, neighbors said, garbage collectors had been picking up bins in the cul-de-sac where the blast happened.

Officials said fire marshals would try to determine the cause of the explosion.

The power of the explosion that destroyed the home on Biddeford Circle in Doylestown, on Tuesday, Jan. 14, 2020, was so great it threw one of the exterior windows into the middle of the cul-de-sac.
