Excerpts from the Dailyherald.com:

An early morning fire in the basement of a single-family house in Naperville left the home uninhabitable. Firefighters were called to the house at 3:09 a.m. on the 1600 block of Gartner Road when residents reported smoke coming from the basement.

Firefighters encountered heavy smoke upon entering the home. It took 20 minutes to extinguish the blaze and another 45 minutes to extinguish smoldering materials and ventilate the house.

About 25 firefighters responded to the scene to battle the fire. The cause is still under investigation.
