This Old House Marvin Sponsorship

Through our partnership, more than 50 handcrafted Marvin windows will be installed during this season’s ambitious update of the Arlington House, an early English-style Arts and Crafts home built in 1909 in Arlington, Mass. As the project unfolds, the beloved “This Old House” cast – Kevin O’Connor, Norm Abram, Roger Cook, Richard Trethewey and Tom Silva – walks viewers through an extensive renovation and remodel using carefully selected materials and products, like the Marvin Next Generation Ultimate Double Hung window, honoring the history of the home while incorporating modern design touches and amenities. Check your local listings (PBS) for showtimes to watch the project come to life.
