HOUSTON -- Firefighters responded to a fire that heavily damaged a 99-year-old woman’s home in southeast Houston early Tuesday.

The Houston Fire Department responded to Oakdale at Palmer in Third Ward around 2:30 a.m.

Firefighters found flames coming through the roof of the two-story home, but no one was home at the time and no injuries were reported.

A contractor who was working on the property tells KHOU 11 News the 99-year-old owner lived at the home for 40 years, and she was just one week from moving back in after recent renovations.

He says he was devastated to find out what happened early Tuesday.

“It’s like a nightmare right now,” said contractor Michael Potts. “It’s a nightmare. I don’t believe this is happening.”

Potts says the owner would come to check on the home every day.

“I’d see a big smile on her face every time she’d come to see the work that was done inside of it,” said Potts.

The home is likely a complete loss.

The woman was reportedly with her daughter in Baton Rouge at the time.

The cause is under investigation. As per standard protocol, arson investigators swept the home as soon as the fire was contained.

Electricity and gas were turned off at the time of the fire, according to the contractor.
