Upon arrival, crews saw heavy fire coming from the second floor and attic of the house, according to the Quincy Fire Fighters Association on Facebook.
The house was set back off the street behind another house, which made it difficult for crews to reach the flames, the association added.

The woman was treated by EMS personnel onsite but it was unknown if she was brought to the hospital, Boston25 reports.
The cause of the fire remains under investigation.
