The Ultimate Window Replacement Experience: Signature Service Meets Exclusive Fibrex® Technology
When you invest in your home, you deserve a process that is as flawless as the final product. At Renewal by Andersen of Milwaukee, our award-winning Signature Service guarantees a stress-free, custom-tailored remodeling experience from start to finish.
But a perfect installation means nothing if the window itself fails over time. That’s why every replacement window we install is crafted from our exclusive Fibrex® material—a revolutionary composite engineered to withstand brutal Wisconsin winters and scorching summers, all while requiring virtually no maintenance.
A Flawless Process Demands a Flawless Product
Any home renovation can feel daunting. That is why Renewal by Andersen of Milwaukee acts as your single point of contact. We don’t just sell windows; we design, build, install, and warrant them.
Our Certified Master Installers take pride in treating your home with the utmost respect. But their expert craftsmanship is only half the story. The true “secret weapon” behind our long-lasting results is the material itself. Because we use Fibrex®, our team can guarantee an airtight, weatherproof fit that traditional wood or vinyl windows simply cannot match.
The Science of Fibrex®: The Best of Both Worlds
What makes Fibrex® the premier choice for Wisconsin homeowners? It represents the intersection of engineering, innovation, and unmatched durability.
Created from a unique blend of 40% reclaimed wood fiber and 60% thermoplastic polymer, Fibrex® gives you the absolute best qualities of traditional window materials without any of their distinct flaws:
The Strength of Wood
Fibrex® provides exceptional structural rigidity, allowing for narrower frames and significantly more visible glass.
The Low-Maintenance of Vinyl
It never requires scraping or painting. It won’t fade, blister, or peel, even in direct sunlight.
Airtight Insulation
Unlike aluminum, Fibrex® has an incredibly low thermal transmittance, keeping your home warm in winter and cool in summer.
Our 4-Step Signature Service (Powered by Fibrex®)
Our comprehensive replacement process is designed around you. Here is how our exclusive material makes every step of our Signature Service exceptional:
1. In-Home Consultation & Custom Design
During your free consultation, our design experts will help you match your home’s unique aesthetic.
The Fibrex® Advantage: Because of its immense strength, Fibrex® can be extruded into virtually any shape or size. It is also available in a wide array of rich, dark exterior colors and real wood interior finishes that vinyl simply cannot support without warping.
2. Precision Measurement & Custom Manufacturing
Every single window and door we install is custom-built to the exact millimeter of your home’s specifications.
The Fibrex® Advantage: Your home is unique, and as homes settle, window frames can shift. The structural integrity of Fibrex® ensures that when we build a custom window to fit your space, the frame will remain perfectly rigid and true to size for decades.
3. Master Installation (Our 7-Step Process)
Our extensively trained crew arrives in a specialized “rolling workshop” truck. We carefully protect your furniture, remove the old windows, and install the new ones while minimizing exposure to the elements. We then seal the gap with specialized insulating foam and apply custom trim.
The Fibrex® Advantage: Wisconsin experiences extreme temperature swings. Vinyl expands and contracts significantly in these conditions, eventually breaking the weatherproof seal. Fibrex® has a remarkably low thermal expansion rate. Once our installers seal your window, it stays sealed—blocking out drafts, leaks, and energy loss year-round.
4. The Ironclad Warranty
When we clean up our workspace and leave your home, your investment remains fully protected. We are one of the few companies that warrant both the product and the installation.
The Fibrex® Advantage: We confidently offer a 20-year transferable limited warranty on glass and Fibrex®, a 10-year warranty on hardware, and a 5-year warranty on installation. We can do this because Fibrex® does not rot, decay, mold, chip, or rust.
