Well before 2000, Mozer Works Inc. was recognized for its high-quality remodeling and building, including work performed in many historic neighborhoods in the DC metropolitan area. Over forty years ago, as a budding builder journeyman, Neil broadened his skills into the area of historic restoration and first found his love of olde things, including olde windows and doors. Recognizing the need for more dedicated specialists in olde building restoration, he decided in 2010 to limit his company's efforts to this specialization with a focus only on the historic restoration of olde entrance doors and windows.

After training with a widely recognized national leader in restoration, Neil and many of his staff have since spent years restoring olde windows and doors to ensure top-quality performance and unmatched beauty. They have been the recipients of awards and acknowledgments for outstanding work in the DC metropolitan area by local preservation commissions, county governments, and historic societies. Before turning to specialized restoration, Neil worked as a general contractor and master carpenter/builder for over twenty-five years with a focus on quality residential projects. He apprenticed in Denver, Colorado, Aargau, Switzerland and around the DC metropolitan region.
