J.D. Power and Associates has released a report ranking window and patio door makers. The first-time study asked consumers who purchased new windows or patio doors to rate those purchases on six factors: ordering and delivery, price competitiveness, operational performance, appearance and design features, operational features and warranty and replacement.
Pella ranked highest in customer satisfaction with windows and patio doors, with a score of 796 on a 1,000-point scale. Pella performed particularly well in operational performance -- which includes ease of use and operation, energy efficiency and ease of cleaning, according to J.D. Power.
Andersen followed closely with a score of 794, performing well in operational features, as well as in appearance and design features. Milgard ranked third with an index score of 788. Further scores include Weather Shield, 782; Loewen, 780; Industry Average, 780; American Craftsman, 762; Marvin, 756; Kolbe & Kolbe Millwork, 754; and Jeld-Wen, 753.
"While product quality and price are important, the key differentiator in satisfaction among consumers who purchase patio doors and windows is service -- particularly with ordering and delivery," said Jim Howland, senior director in the real estate industries practice at J.D. Power and Associates.
The study found 45 percent of consumers report installing the windows or patio doors themselves or with help from family or friends. Approximately 30 percent hired an independent contractor or remodeler to perform the installation, while 20 percent used an installation service provided by a home improvement retailer. Only 5 percent of consumers report using an installation service provided by the window or patio door manufacturers.
