GBMFD crews responded for a report of something burning in the basement, the house is filling with smoke.
Station 8 arrived on scene and reported smoke showing from the structure. The E8 Captain directed a hoseline into the basement from the exterior stating he had heavy smoke on the first floor with high heat at the point of entry, occupants were evacuated.
Next arriving companies secured additional water supplies and pulled backup lines to support the initial crew. Due to the difficulty finding the fire, this incident was upgraded to a Working Still alarm.
Once the fire was located and knocked down from the exterior, crews then made entry and extinguished it.
