Andersen Windows

Compare Window Products, Installation & Warranty Coverage

Homeowners considering Andersen windows need more than a product name. The right replacement depends on the opening, frame condition, window style, glass, material, installation method, and warranty responsibilities.  provides residential replacement window estimates and installation, and we can confirm which products are currently available for your project.

We’ve served homeowners since 1977 and completed work for more than 1.2 million customers across 11 states. That experience helps us identify the practical questions that should be answered before you select a window or installation provider.

Understanding Andersen Window Series & Materials

Andersen product families include the 100 Series, 200 Series, 400 Series, A-Series, and E-Series. These names are useful starting points, but product availability varies by provider. Materials, configurations, finishes, glass options, and intended applications vary among the series.

Some Andersen products use Fibrex composite, a material made from wood fiber and thermoplastic polymer. Other products may incorporate wood, vinyl, aluminum, or combinations of materials. Rather than choosing by series name alone, consider how the complete window fits your opening and meets your preferences for appearance, maintenance, and operation.

Our own replacement window offerings include double-hung, casement, slider, garden, bow and bay, awning, specialty, transom, and basement hopper windows. Castle Windows-branded windows are designed, engineered, tested, and manufactured in our North American factories. This manufacturing information applies to our windows, not to products manufactured by Andersen.

Lifetime Coverage for Windows We Install

Every window we install, including those from Andersen, is backed by our lifetime, non-prorated warranty. Coverage includes leaks and drafts, vinyl, color, glass, seals, parts, screens, window operation, and installation labor. Our warranty also transfers to a new owner at no charge.

We provide free lifetime service labor for covered warranty requests, along with 24-hour personal assistance for warranty service. That distinction matters because a product warranty and an installer’s labor commitment aren’t necessarily the same protection. Andersen warranty terms remain specific to the selected Andersen product and installation arrangement.

Our long-term service commitment is supported by a business that has operated for more than four decades. We’ve received multiple Qualified Remodeler Top 500 designations. According to Qualified Remodeler reporting referenced by our company, we’re one of only two businesses among its 1998 top-50 remodelers to have moved up in both volume and size.
