BOSTON (WHDH) - Fierce flames took over a windowless commercial building on Blue Hill Avenue in Mattapan early Tuesday morning.
Firefighters cut through the Bay State Linen garage doors to get in and battle the fire with foam and water.
Deputy Chief Joseph Fleming said it took crews five to ten minutes to figure out what was burning due to the smokey conditions.
As of 8:30 a.m., Woodrow Avenue remained closed but officials reopened Blue Hill Avenue and Ashton Street.
Officials are working to determine the cause and point of origin of the fire.
Fleming estimates about a million dollars in damages.
