The Window Man is a family owned and operated business serving the DC Metropolitan Area, Northern Virginia and parts of Maryland for 30 years. Known as "The Educational Window Company", due to our business philosophy of, "We Educate, You Decide. We don't believe in high-pressure sales pitches or pricing gimmicks. We carry many brands and materials, yes. But our most popular replacement window (and for obvious reasons once you compare) is by far the Infinity from Marvin Ultrex Fiberglass replacement window. 8X stronger than cheap vinyl, the Infinity Ultrex Fiberglass window will never rot, warp, bend or bow! Strong profiles allow for narrow frames and sashes, which allow for more natural light and expanded views. We also carry the industry-leader in Secondary "Storm" Windows, the Mon-Ray High-Performance "Storm" Window. Love your wood windows? Great! Then keep them by simply adding a Mon-Ray Secondary "Storm" Window. We offer FREE In-Home No-Obligation Consultations! Or, if you prefer, you can visit either our fully-staffed "Hands-On" showroom, which is open 6 days a week. In our showroom, you will find full-size, installed windows that you can take for a "test drive" side-by-side-by-side...we believe it's the finest showroom going in all of the replacement window industry.
