FALMOUTH — No one was injured in unrelated fires that damaged two Falmouth homes Wednesday.

Falmouth firefighters responded to an unoccupied house at 14 Andys Lane at about 3:45 p.m. after neighbors reported smoke coming from the building, Deputy Fire Chief Timothy Smith said.

“When we got there, there was a very active fire in the basement,” Smith said. “As we were getting into position it had started to progress quite a bit. We were able to get in there and keep it contained to the basement and first floor.”

The house had lost power during Tuesday's blizzard, and the fire occurred at about the time that power was restored, Smith said. It was put out in about 20 minutes, he said.

The home had extensive smoke, water and heat damage, he said.

The cause of the fire is under investigation.

Earlier in the day, firefighters responded to a house at 52 Cliffwood Lane after a smoke detector woke the home’s two occupants at about 3:30 a.m., Smith said.

The fire was contained to a wall behind a fireplace that had been used for several hours to heat the home, which was without power, he said.

The fire was likely caused by extensive use of the fireplace and possibly a defect in the wall, Smith said.

The house had minor smoke and water damage, he said.
