When Nancy Lyons started Lyons Historic Window in 2003 in Denver, Colorado, “window restoration” was not a familiar term to most people west of the Mississippi.  Convincing people of the value of their historic windows was an uphill battle.  Today, owners of vintage homes recognize that well-kept original woodwork brings value to their homes.  Environmentally conscious people understand that that saving windows is saving energy, and old, drafty windows can be made efficient.  Thanks to a blossoming of restoration companies from coast to coast in recent years, window restoration is no longer the esoteric term is once was.  We are grateful for all of the historic preservation educators that helped to stem the tide of cheap vinyl windows We are grateful to each and every homeowner that makes a decision to treat their historic home with dignity and say “no” to cheap off-the-shelf replacement windows – your stewardship of our invaluable historic resources is commendable. Thank you.
