No. We get this question often, and the confusion is understandable because both companies sell windows with the Andersen name on them. The relationship is different, though, and it affects what you can buy and who shows up at your house.
Who Renewal by Andersen Is
Renewal by Andersen is a division of Andersen Corporation, founded in 1995, that sells and installs one product: its own Fibrex composite replacement window, plus a matching patio door line. It sells through company-owned and affiliated locations using in-home sales consultations, and installs with its own certified installers. It is a legitimate Andersen company with its own warranty and its own service organization.
Who Wood Windows Inc Is
Wood Windows Inc is an independent, locally owned window and door dealer and installer in Garden City, Idaho, in business since 1980 — 46 years in the Treasure Valley. We are an authorized Andersen dealer, which means we sell the full Andersen catalog: 100 Series, 200 Series, 400 Series, A-Series, E-Series, patio doors and the Architectural Collection big doors. We also carry Marvin, Milgard, Kolbe, All Weather Windows, VELUX and Therma-Tru. Every installation is done by our own employees — never subcontractors — and we service what we sell out of our Garden City shop.
The Differences That Matter to a Homeowner
| Renewal by Andersen | Wood Windows Inc | |
|---|---|---|
| Ownership | Division of Andersen Corporation | Independent, locally owned since 1980 |
| Products | One Fibrex replacement window line | Full Andersen range plus Marvin, Milgard, Kolbe and others |
| Materials offered | Fibrex composite | Fibrex, vinyl, fiberglass, clad wood, aluminum-clad wood |
| Sales process | In-home consultation, single-brand | In-home measure, multi-brand comparison quote |
| Installers | Renewal certified installers | Wood Windows employees |
| Warranty service | Renewal's warranty, through Renewal | Andersen's Owner-to-Owner warranty, serviced locally by us |
The practical difference comes down to range and comparison. If you already know a Fibrex replacement window is what you want, Renewal offers a well-run single-product path. If you want to see a 400 Series clad-wood window next to a Marvin Elevate and a Milgard vinyl unit on one quote, with NFRC numbers for each, that is what an independent dealer exists to do.

Frequently Asked Questions
Can Wood Windows service a Renewal by Andersen window?
We service Andersen products generally, and our crews can adjust, repair or replace most Andersen units. Renewal by Andersen windows, though, are sold under Renewal's own warranty, and warranty work is normally handled through the Renewal location that sold them. If you have a Renewal window that needs attention, call us and we'll tell you honestly, case by case, whether we're the right people to fix it or whether Renewal should.
Is the Andersen 100 Series the same as Renewal by Andersen's Fibrex window?
Same material, different product. Both are made of Fibrex, Andersen's composite of reclaimed wood fiber and thermoplastic polymer. The 100 Series is Andersen's dealer-channel Fibrex line, sold through independent dealers like us in new-construction and replacement configurations. Renewal's window is a separate design built for Renewal's replacement business and available only through Renewal.
Which is cheaper, Wood Windows or Renewal by Andersen?
We don't quote a competitor's pricing, and Renewal sets its own. What we can tell you is that we quote each window line by line with the NFRC ratings attached, across Andersen's full range and three other brands, so you can compare a 100 Series, a 400 Series and a Marvin or Milgard equivalent on the same sheet. We encourage homeowners to get more than one quote and compare the specs, not just the totals.
