  • In 1973 Jim Gravina starts his own window company and begins to focus on window and door replacement.
  • Throughout the ’70s & 80’s the company grows by hiring its own team of installers and service people.
  • In the 90’s Gravina's began offering composite windows and doors. This gives homeowners a maintenance-free window and door solution.
  • In the early 2000’s Gravina's Window Center of Littleton switches to all fiberglass windows by becoming the first Infinity from Marvin window dealer in the country.



Today, Gravina's Window Center of Littleton offers the full Marvin product line, with the focus still on Infinity fiberglass windows. Through its dedicated team of sales and installation professionals, Gravina's Window Center of Littleton will continue to offer the best overall value on the market. A strong culture of family and community continues today to offer the best homeowner experience possible.


Gravina's Window Center of Littleton is a regular contributor to charitable causes such as the Special Olympics, local schools, youth leagues, and events.
