How It All Began

Our business is guided by our Christian faith and desire to always do the right thing.

  • Exclusive Product: We are the exclusive Georgia dealer for Infinity from Marvin fiberglass windows, a partnership we chose to ensure you receive only the highest quality windows.

  • Mission-Driven: Our purpose is to make window and door shopping simple.

  • Values: Our passion is to bring more Light into the homes and lives of our customers and community.

Like many great businesses, NGRW had humble beginnings. NGRW launched in 2005 operating initially from a spare bedroom and later from the basement of the founder's home in Cumming, GA. During this period, the company processed its first orders, managed client communications, and began establishing operational procedures that would form the foundation for future growth.

In the early years of growth, NGRW aimed to be a little bit of everything for everyone, offering a wide variety of window types to meet diverse customer needs.

In 2012, NGRW welcomed its most loyal team member — Duke, our four-legged "Pawject Manager." Known for greeting customers with tail wags and impressive tricks, Duke also takes his unofficial duties seriously: sniffing out leftover snacks, enjoying spoonfuls of peanut butter, and bravely (or not-so-bravely) avoiding spiders. When Duke isn't at the office, he's known to pout until he can get back to work.

Going All-In With Infinity From Marvin

By 2016, we had sold 26 different models of windows — but we knew our customers deserved the very best. That year, we made the decision to go exclusive with Infinity from Marvin, offering homeowners top-quality fiberglass windows backed by exceptional design and performance.

Expanding Our Office Space

In 2017, our growing team needed more room to collaborate and serve customers. We purchased Suite 700, adding it to the two suites we already occupied — creating the space and resources needed to keep up with our rapid growth.

EOS gave us a clear plan for how we work, helped us get everyone on the same page, and allowed us to put our processes down on paper so we can keep delivering consistent, high-quality service as we grow.
