As of 2015, J.D. Power and Associates ranks Renewal by Andersen as the highest in customer satisfaction for their window and door brands. Pella and Window World are second and third, respectively.
Home improvement expert Bob Vila says that Pella goes above and beyond with its vinyl windows by injecting argon in between the panes, improving the heat and cold insulation. He advises to look at triple-paned windows as well.
While replacing windows can be costly, consider that Remodeling magazine's 2014 Cost vs. Value Report shows that window replacement offers a high return on investment. Homeowners can expect around 79 percent return on sale of the home.
