Ply Gem - Cornerstone Building Brands Reviews

The overall sentiment toward Ply Gem, as reflected in recent customer reviews, is overwhelmingly negative. Reviewers consistently note significant problems with the company’s window and door products, particularly citing manufacturing errors, poorly made hardware, and glass quality issues. A common thread is frustration with Ply Gem's customer service—delays, lack of follow-up, or non-responsiveness are frequently mentioned, with some reviewers highlighting years of positive experience now marred by recent declines. Although there is a clear sense that installation professionals and homeowners want reliable windows, repeated references to subpar support and a lack of issue resolution dominate the feedback.

Frequent themes in the reviews include poor quality control during production, repeated warranty claim challenges, and difficulty obtaining replacement products. Many customers mention incorrect or defective units being delivered—sometimes multiple times—and a lack of timely communication from service representatives. Warranty support in particular is a pain point, with several customers describing extensive wait times, unfulfilled promises, or being bounced between departments without resolution.

In summary, Ply Gem’s reputation among customers and installers is currently very poor, with service and product deficiencies affecting both homeowners and professionals in the window installation sector. Based on the consistent complaints, particularly regarding warranty claims and quality control, Ply Gem is generally regarded as unreliable in its current operations. Customers emphasize unresolved problems in multiple regions, signaling widespread dissatisfaction rather than isolated concerns.
