Firefighters were able to contain a two-alarm fire at a rental company building in Healdsburg late Tuesday night, a Sonoma County fire dispatch supervisor said.

Initial calls shortly after 8 p.m. reported that the fire was fully involved and spreading to the roof of Aaction Rent at 1430 Grove St.

Firefighters responded in about five minutes and almost immediately called a second alarm to combat the spreading flames.

As of about 9:20 p.m., firefighters were continuing to put out small fires inside the building, however the blaze was mostly under control by then, fire officials said.

Multiple agencies responded to the fire, with Healdsburg fire leading the effort. Fire departments from Windsor, Geyserville, Santa Rosa, Cloverdale, and Rincon also responded. Forestville firefighters provided station coverage.

No injuries were reported and the cause of the fire remains under investigation
