STAFFORD, Texas – The Stafford Fire Marshal’s Office is now investigating an explosion at a warehouse building early Thursday.

Stafford Police said they started receiving calls just before 4 a.m. of a loud noise. Some of those calls came in from as far as two miles away from the explosion, which happened at Jimerson Underground Inc., located in the 300 block of Brand Lane near South Main Street.

Janie Saucedo lives right next door to the local company that specializes in underground utility installation.

“It shook everything. I mean it really shook the whole house,” said Saucedo hours after the explosion. Two of her windows shattered, she said, as a result. One window in a bedroom, the other overlooking her patio.

She described the fire that followed as having “a really sour smell.”

Stafford firefighters were able to quickly extinguish the fire that burned through the warehouse used to store a jet ski, a barbecue pit used for competitions and a restored white 1965 Ford Mustang.

Luckily, no one was inside the building at the time of the explosion.

The building suffered extensive damage that affected the structural stability of the entire building. Fire investigators said they had to wait until daylight to begin their work which could take the better part of Thursday.

The owners told KHOU 11 News they think the stored barbecue pit may be linked to the explosion. They also confirmed they have insurance and are open to helping neighbors like Saucedo pay for repairs to their homes.
