What Happened to CertainTeed Windows? The Rise of MI Windows and Doors

CertainTeed, once a prominent player in the replacement window industry, has undergone a significant transformation in recent years. In 2011, the company announced that MI Windows and Doors would be manufacturing all of their window series, marking a major shift in the industry. This move came as a surprise to many installers and industry insiders who had mixed feelings about the consistency of CertainTeed’s window quality.

The decision to have MI Windows and Doors take over the manufacturing of CertainTeed windows was likely a strategic one, as MI had the resources and expertise to ensure a more consistent level of quality. However, the transition has not been without its challenges, as some have argued that MI has struggled to maintain the same level of quality as CertainTeed had in the past.

The Rise of MI Windows and Doors

MI Windows and Doors, a Pennsylvania-based company, has been manufacturing CertainTeed-branded windows since 2007. The company has a long history of producing high-quality windows and doors, and their partnership with CertainTeed has allowed them to expand their reach and offer their products to a wider audience.

In 2021, MI Windows and Doors made headlines when they acquired Sunrise Windows, a move that was seen by many as a way to further strengthen their position in the market. The acquisition allowed MI to offer an even wider range of window products, including Sunrise’s line of high-quality vinyl windows.

The Current State of CertainTeed Windows

Today, CertainTeed windows are still available on the market, but they are manufactured exclusively by MI Windows and Doors. The company offers a wide range of window styles, including double-hung, casement, slider, and picture windows, as well as architectural shapes and bay and bow windows.

CertainTeed windows are known for their energy efficiency, with insulated double-pane glass and virtually maintenance-free frames. Many of their products also come with a limited lifetime warranty, providing homeowners with added peace of mind.

Despite the changes in ownership and manufacturing, CertainTeed windows remain a popular choice among homeowners and contractors. The company’s reputation for quality and innovation has helped to maintain their position in the market, even as MI Windows and Doors has taken over the manufacturing process.

The Impact on Homeowners and Contractors

The transition from CertainTeed to MI Windows and Doors has had a significant impact on homeowners and contractors who have used CertainTeed windows in the past. For homeowners who are seeking to replace their windows, the change in manufacturer may raise questions about the quality and performance of the new MI-manufactured windows.

Contractors, on the other hand, may need to adjust to working with a new manufacturer and may need to familiarize themselves with MI’s installation processes and warranty policies. However, many contractors have welcomed the change, as MI has a strong reputation in the industry and has been able to maintain the high level of quality that CertainTeed was known for.

Despite the challenges, the partnership between CertainTeed and MI Windows and Doors has ultimately been a positive one for the industry as a whole. By combining CertainTeed’s brand recognition and reputation with MI’s manufacturing expertise, the companies have been able to offer homeowners and contractors a high-quality product that meets their needs.
