A fire starting in an unattached garage significantly damaged a home in Robertsville early Tuesday morning.

Pacific Fire Chief Rick Friedmann said the fire completely engulfed the garage before spreading and damaging nearly 50 percent of the modular home in the 5400 block of Finney Place. There were no injuries.

Friedmann said it is currently known the fire started in the garage, but an investigation is ongoing to determine the actual cause.

Pacific fire officials were alerted to the fire Dec. 31 at 2:14 a.m. Friedmann said the residence was more than four miles away from the station and down an unfriendly one-lane road causing crews to show up close to 20 minutes after the call. Friedmann said crews were able to make up for lost time and quickly extinguished the fire.

“We actually got a pretty quick knockdown on it,” he said. “... We had a pretty good little travel time, but once we got there we got it knocked down in 20 to 25 minutes.”

Friedmann said one of his chief officers lives in the area and was first on the scene. When the officer arrived, the 20-by-30-foot unattached garage was 100 percent involved and the fire was moving to the residence.

“We had extension into the residence and it got the attic and the back two rooms,” Friedmann said.

Friedmann said the home is currently unlivable, but the owners, who escaped harm after hearing crackling from the garage fire, should be able to salvage many personal items.

“We cut it off quickly and the side of the house that caught fire was actually a storage area,” he said. “Their bedrooms were just affected with some light smoke.”

The fire was large enough that backup was called in to assist. Friedmann said trucks from St. Clair, Cedar Hill, Eureka, Metro West and Boles responded to the call. He said trucks from Union and Valley Park provided backup.

“It was a full first-alarm assignment and then we added two more tankers to it,” he said.

Even though the crews were able to put the fire out fast, Friedmann said equipment was on site until close to 5 a.m.

“We probably had it under control in about 30 minutes, but we had a pretty extensive mop-up” Friedmann said.

Friedmann said some officials stayed in the area to wait for daylight to begin the investigation immediately.
