Our Story

In 1980, Walt Svend Nielsen, son of Danish parents, set up a small windows, blinds, awnings and skylights business in Roswell, Georgia called the W.S. Nielsen Company. The business rapidly grew through the 80’s as it expanded from residential into fast food restaurants.

In 1985, the W.S. Nielsen Company landed a rounded glass solarium ‘greenhouse’ dining area for a Wendy’s restaurant. That one job lead to 1,200 Wendy’s, then expanding to all fast food restaurant chains: Arby’s, McDonalds, Chick fil-A, Burger King and more.

The industry shifted from fast food to the construction of mega malls in the 90’s: Phipps Plaza, Carolina Place, Mall of Georgia, Lenox, Perimeter, Coral Ridge, West Oaks, Mall of Louisiana and more. They all had one thing in common, monumental custom glass skylights.

"W.S. Nielsen Company is a family-owned specialty contracting business with a 40+ year history of Safety, Quality and Productivity.  We are proud of our excellent employees and loyal customers. We cherish these relationships like family!"

Mike NielsenPresident

In 2003, Walt’s son, Mike, became president and Walt stepped into enjoying retirement. Mike’s commitment was and is to continue the core business of skylights and to expand… offering more products in order to better serve the architects, owners and general contractors we serve.

Still run as a family business, W.S. Nielsen established Core Values: Safety, Quality, Productivity and began winning industry safety awards for very challenging installations, year after year.

Today, we have 11 Alpharetta based office staff and 16 field staff, each playing a critical role in a $13m+ business which continues to grow and offer new products every year. View our product portfolio.

In addition to elements on new construction, we have a dedicated renovation team which helps replace products which are at the end of their life cycle or become damaged from weather or other sources
In May 2018, W.S. Nielsen moved into a beautiful new building where we host Architectural AIA Training programs and other client, manufacturer and installation training events. Each year, our story evolves and becomes more exciting. One thing is certain, as long as there are cranes on our skylines, we will continue offering world class specialized construction products designed to save our clients time and money.

Support and Outreach

Yes, the purpose of a for profit business is to make money. However, at W.S. Nielsen, it’s not all about profit; it’s about a higher-level purpose of impacting, helping, influencing and educating those in our community and those who have sacrificed for all of us. Mike Nielsen looks for ways for our company to get involved. Whether it’s providing blankets to those in need, teaching students a construction skill, or flying Veterans to memorials. W.S. Nielsen does not just get behind, we Champion!

Our staff is encouraged to get involved, give of their time and make a difference.  The logos below are the affiliations and organizations we find ways to impact.  As a business, being profitable allows us to make a difference… ‘Pay it Forward!’

Got a cause we should consider? We are always looking for ways to enrich lives.
