Pivot to Digital Consultations Helps Window and Patio Door Industry Ride Home Improvement Wave, J.D. Power Finds

Renewal by Andersen Ranks Highest in Manufacturer Segment and Ranks Highest in a Tie with The Home Depot in Retail Segment

Despite the economic and logistical challenges introduced by the COVID-19 pandemic, consumer spending on home improvements and repairs grew more than 3% to nearly $420 billion in 2020.1 One surprising beneficiary of this trend is the window and patio door industry, which is heavily reliant on in-home consultations. According to the J.D. Power 2021 U.S. Windows and Patio Doors Satisfaction Study,SM released today, the industry’s efforts to adjust its business model to accommodate virtual consultation and offer discounts and incentives has helped drive higher customer satisfaction.

“Unlike other areas of the home improvement marketplace, window and patio door sales are often driven by an in-home consultation with experts who can talk consumers through not only their window options but also provide specific recommendations based on the home layout and design,” said Christina Cooley, director of home intelligence at J.D. Power. “Consistently, we find that manufacturers and retailers that make it easy to comparison shop and provide expert guidance are those that perform best in the study. This past year, they had to adapt, and many did so successfully. A majority—54%—of customers had some form of expert consultation and 11% of those consults were conducted virtually.”
