Fire crews in Montgomery County had to act quick as a fast moving house fire broke out early Friday morning.

Officials say the flames erupted at a home in the 400 block of Penn Street in Pennsburg around 12:30 a.m.

The home partially collapsed after heavy fire damage on both the first and second floors.

Firefighters were able to eventually knock down the blaze and no one was injured.

There is no word on a cause.
