About Us Designing Windows Plus, a family owned and operated business, was founded in 1985. At that time we served Middlesex, Monmouth and Somerset Counties selling custom window treatments. Our business quickly expanded through word-of-mouth referrals due to our commitment to quality, sales and service. We only work with the finest components in window shading from renowned manufacturers such as Hunter-Douglas, Prestige, Comfortex and Normans. WHY CHOOSE DESIGNING WINDOWS OVER THE BIG BOX STORE? Because we specialize in window treatments, we are able to give great price and value in selection. With Designing Windows you get a designer who comes to your home, free of charge, to help you make selections and measure your windows. You also get professional installation free.
