Warranty Comparison

Windows Warranties Comparisons

When comparing window warranties, it’s important to look beyond the fine print. While Milgard Windows, Anlin, Andersen, JELD-WEN, Ply Gem, and Simonton are among the larger players in the industry, smaller regional manufacturers may also offer attractive warranties. However, company size and financial stability play a huge role in how valuable those warranties actually are. For example, a large company with billions in gross sales can withstand warranty claims over decades. Smaller companies, by contrast, may struggle especially if the company doesn’t set aside warranty reserves from each sale, it risks paying today’s warranty claims with tomorrow’s sales revenue, which can lead to serious financial strain or even closure. I have seen this several times with smaller manufacturers and when they close the doors, they leave the homeowner without warranty or the ability in many cases to find parts. Homeowners should weigh both the written terms of the warranty and the long-term viability of the manufacturer.

Company Size and Gross Sales

Understanding company size is critical when evaluating warranties. Larger manufacturers are more financially capable of honoring warranties long-term:

• Milgard Windows (owned by MI Windows & Doors / MITER Brands): Over $2 billion annual sales.
• Anlin Windows & Doors (owned by PGT Innovations): PGT Innovations revenue approx. $1.5 billion annually.
• Pella Corporation: Estimated $2+ billion annual revenue.
• Andersen Corporation: Approx. $3.5 billion annual revenue.
• JELD-WEN: Publicly traded, approx. $4.3 billion annual revenue.
• Ply Gem (part of Cornerstone Building Brands): Cornerstone revenue approx. $5 billion+ annually.
• Simonton (owned by Cornerstone Building Brands): Backed by same $5 billion+ revenues.

By comparison, smaller regional manufacturers that are privately held do not have publicly reported multi-billion-dollar sales figures. Their revenues are typically a fraction of the majors, leaving them more vulnerable if faced with high volumes of warranty claims. This is especially true if warranty reserves are not accrued from each sale, which can cause problems during widespread product failures like bad seals in the dual pane glass units.

Why Milgard Windows Are a Strong Value

When weighing warranty terms against overall product value, Milgard consistently stands out as one of the best choices for homeowners. Milgard’s Tuscany and Trinsic vinyl lines provide Full Lifetime coverage for both parts and labor, something that only Anlin comes close to matching. Unlike many competitors that limit labor to 2 years (Pella) or exclude it entirely (Simonton, Ply Gem), Milgard covers labor for the lifetime of the original owner within its service territory. This means homeowners are not surprised with costly service charges years down the line.

In addition, Milgard includes lifetime glass breakage on Tuscany windows — a benefit very few brands offer. Combined with lifetime frame and component coverage, this makes Milgard warranties among the most comprehensive in the industry. Even when compared against larger corporations like Andersen or JELD-WEN, Milgard holds its own in warranty protection. For the price point of Milgard vinyl and aluminum products, homeowners receive not only strong design and energy efficiency, but also warranty coverage that protects the investment long after installation.

From a risk perspective, Milgard is backed by MITER Brands, a $2+ billion company, giving customers confidence that the company will be around to honor warranties decades into the future. For homeowners who want the peace of mind of a lifetime warranty without paying a premium for high-end wood or fiberglass lines, Milgard Windows strike the right balance between cost, quality, and protection.
