To understand the features & benefits of Grandura/Simonton Vinyl-Clad Windows you need to know about Amcraft Building Products Company, the world's leading supplier of exterior home products. It has seven-billion dollars in annual sales, owns an A+ rating from the Better Business Bureau, and has been around for over three decades.

Amcraft earns its living as a premium distributor of the very best doors, windows, gutters, siding, and other building materials. They are not a manufacturer. And so they invented Grandura: a program that pairs what they determine to be the very best vinyl-clad window with the top one-percent of replacement window dealers in the country, allowing only one contractor/installer per market region.

The window they chose is the Simonton Premium Vinyl-Clad Window. Simonton has ranked highest in an annual J. D. Power customer satisfaction survey for the last four consecutive years.

The exclusive local dealer they chose is Genesis Exteriors, a consistent winner of the Angie's List® Super Service Award. The designation is awarded annually to approximately five percent of all the companies rated on the Angie’s List website, which is the nation’s leading provider of consumer reviews on local service companies.

Why should you care? It's the lifetime guarantee.

Amcraft believes they can sell more Simonton Vinyl-Clad Windows than anyone on the planet by offering a guarantee that’s out of this world. And the way they can do that (with minimum risk to their brand, reputation, and bottom line) is to offer the very best vinyl-clad window installed by the very best local contractor, and then guarantee it like nobody else in the business.

So what exactly is the guarantee?

For as long as you own your home you'll bear zero cost for any materials or labor in the extremely unlikely event that a Grandura/Simonton Vinyl-Clad replacement window installed by Genesis Exteriors develops a problem. More exactly:  

  • Amcraft guarantees each Grandura/Simonton Vinyl-Clad Window installed in your home by Genesis Exteriors with a transferable Lifetime Materials Warranty that includes the vinyl, the hardware, the insulating glass unit, and the screen.
  • Amcraft additionally guarantees each window installed by Genesis Exteriors for life against glass breakage or screen damage caused by accidents, storms, hail, errant baseballs—whatever.
  • There is also an Extended Guarantee for Labor. For the first five years Amcraft will pay for all labor required to replace a window that develops a problem due to a manufacturing defect—and Genesis Exteriors will do so afterward for another five years.
  • The Amcraft Lifetime Materials Guarantee is transferable should you sell your home—effectively a double lifetime warranty on materials.

Remember: a guarantee is only as good as the company that issues it.

No other Madison replacement window contractor can offer a warranty this long or comprehensive as Genesis Exteriors because no other Madison window dealer/installer has been selected by Amcraft to fully guarantee their work while offering a vinyl-clad replacement window of Simonton quality. And you can rest assured that we will be here years from now to honor your warranty—both materials and labor. Consider:

  • Amcraft Building Products Company is a multi-billion corporation that has been in business over 30 years
  • Simonton has been making windows since 1946, employs over four-thousand people, and is part of Fortune Brands, a four-billion dollar home & security corporation.
  • And Genesis Exteriors craftsmen have been providing quality remodeling services to Dane County and South Central Wisconsin homeowners and businesses for over a decade, having completed well over 1000 exterior remodeling projects in the last five years alone: roofs, siding, windows, doors, and gutters.
