Widely regarded as one of America’s most prestigious and influential consumer emblems, the Good Housekeeping Seal is a symbol of manufacturing excellence. For homeowners, it's a powerful guarantee, offering confidence in their investment alongside an additional two-year limited warranty exclusive to products bearing the Seal. If a product that holds the Seal is found to be defective within two years of purchase, Good Housekeeping — not the manufacturer — will replace it or refund up to $2,000 of the purchase price. Paired with the Simonton brand’s Lifetime Limited Warranty, this supplemental warranty provides unmatched reassurance for homeowners.

“This isn’t just an endorsement — it’s a testament to an unwavering commitment we have to bring the best products to building professionals and homeowners,” said Rose Lee, president and CEO of Cornerstone Building Brands. “For more than 75 years, the Simonton brand has stood for quality, service and innovation — giving homeowners confidence that they are investing in windows that truly deliver the highest quality and performance. This recognition of excellence solidifies the brand’s place as a trusted industry leader that customers can rely on.”

Earning the Good Housekeeping Seal is no easy feat. Products undergo hundreds of hours of independent review and lab testing by a highly accredited team of engineers, scientists, analysts and product experts at the Good Housekeeping Institute to verify performance claims.

“The double hung and sliding windows that earned the Good Housekeeping Seal underwent rigorous evaluation by our experts to ensure the highest level of performance, safety and efficiency,” said Dan DiClerico, director, Home Improvement & Outdoor Lab at the Good Housekeeping Institute. “Through extensive operations testing in the Home Improvement & Outdoor Lab at the Good Housekeeping Institute, our experts also verified the construction quality of the units, for example checking the fusion-welding on the one-piece frames, as well as usability and convenience features like the tilt-in sashes on the double-hung windows.”

The Simonton 5500 and 6500 Double Hung windows are known for their durability, wide range of styles and advanced energy-saving features. In fact, select triple-pane windows from these product lines have also earned the ENERGY STAR^® Most Efficient 2024 designation, highlighting them as some of the best-performing windows in their class.

Similarly, Simonton 6200 and DaylightMax Sliding windows are designed with security and weather resistance in mind. Their AutoSense™ lock, which self-latches upon closing, offers enhanced protection, meeting the nation's most stringent forced entry code requirements. This gives homeowners peace of mind that their home is safe and protected from both intruders and the elements.

“Given the huge impact windows have on the look of the home, it helps that the Simonton units are beautiful, too," DiClerico added. "With Simonton windows, consumers have a superb option for their next window project."

Crafted with care in the USA, Simonton-branded premium vinyl windows and patio doors are designed for long-lasting durability, effortless use and superior weather protection.
