When homeowners begin exploring window replacement options, it’s common to come across two familiar names: Andersen Windows and Renewal by Andersen. Both are part of the Andersen Corporation, a leader in the window and door industry with over a century of innovation and craftsmanship. However, while we share the Andersen name and heritage, Renewal by Andersen operates with a distinct focus and approach.
As Renewal by Andersen, we’re the full-service window and patio door replacement division of Andersen Corporation—designed specifically to work directly with homeowners like you. If you’ve ever wondered how our services and products differ from Andersen Windows, here’s a clear comparison to help guide your decision.
Manufacturer vs. Full-Service Replacement
Andersen Windows functions primarily as a manufacturer. Their windows and doors are sold through a network of retailers, home improvement stores, and independent contractors. They mainly serve the new construction market, offering a broad range of window series that cater to different project types, budgets, and architectural needs.
At Renewal by Andersen, our model is different. We’re not just a product supplier—we’re a full-service provider specializing in the replacement of windows and patio doors in existing homes. From the first consultation to installation and post-installation service, we manage every step of the process. Our direct-to-consumer model is designed to make the window replacement experience easier and more personalized for homeowners.
Product Scope and Material Differences
Andersen Windows offers a wide product portfolio across several series, including the 100, 200, 400, A-Series, and E-Series. Each line varies in material and performance characteristics, ranging from vinyl-clad wood to aluminum and composite options. They're built mainly for new construction applications, giving contractors and homeowners flexibility to mix and match styles and materials for large-scale projects.
At Renewal by Andersen, our focus is singular but specialized: custom-crafted replacement windows, entry doors, and patio doors built exclusively with our proprietary materials. Fibrex®, the main material used in our windows, offers the strength and insulating performance of wood with low-maintenance benefits. We’ve chosen Fibrex® for our windows because it resists warping, cracking, and fading—ideal for homes looking for long-term energy efficiency and durability in every climate.
Enhance your home with custom Renewal by Andersen entry doors and patio doors, expertly crafted using our exclusive, proprietary materials. These advanced materials are specifically engineered to deliver exceptional durability, strength, and low-maintenance performance for your doors. While our windows famously feature Fibrex® material—known for its wood-like strength and insulation without the upkeep—our door materials embody a similar commitment to innovation, ensuring long-lasting beauty and reliable function.
Installation: Who Does the Work Matters
One of the key differences comes down to installation.
With Andersen Windows, installation is typically handled by independent contractors or the homeowner’s chosen professional. While this allows flexibility, it can also introduce variability in service quality and installation practices.
We take a different approach at Renewal by Andersen. All our installations are handled by our own Certified Master Installers. These are trained professionals who specialize in installing our products. This allows us to maintain rigorous quality control and ensures each window or door is fitted with precision. It’s a vital part of our Signature Service promise, which brings together the best people, a superior process, and an exclusive product—all backed by one-company accountability.
Warranty and Peace of Mind
Warranties are an important consideration when investing in new windows or doors.
Andersen Windows offers product warranties through its network of dealers, but the scope and service terms can vary depending on the retailer or contractor you work with.
At Renewal by Andersen, our limited warranty covers both the product and the installation—and it's fully transferable. Because we manufacture and install the product ourselves, there’s no finger-pointing if service is needed later. This streamlined accountability adds long-term value and peace of mind for homeowners.
Who We Serve
Ultimately, the choice between Andersen Windows and Renewal by Andersen depends on your project needs.
- If you're building a new home or working with a contractor on a large renovation that involves multiple building materials and suppliers, Andersen Windows may be the right fit.
- If you’re a homeowner looking to replace your existing windows or patio doors with a custom-fit, professionally installed solution—Renewal by Andersen is purpose-built for you.
