• ✓ Made in the USA

  About: "AMERICA'S OLDEST WINDOW MANUFACTURER For more than 170 years, Mathews Brothers has called Maine home." "Manufactured in Maine by a team we are proud to work alongside, every Mathews Brothers product..." "Mathews Brothers operates from our Belfast headquarters and manufacturing facility on Perkins Road, with additional production and office operations at our Hermon location on Logistics Lane." Official pages reviewed do not use the exact phrase "Made in USA" or "American-made"; the best official wording is manufactured in Maine at the Belfast (and Hermon) facilities. Caveat: production is split between Belfast and a second manufacturing center in Hermon that became fully operational in 2022. Official pages reviewed do not list a street number on Perkins Road or a phone number.
