P.E. Guerin is the nation's oldest decorative hardware firm, designing in the moment since 1857. In addition to our expansive product line, designers and architects can design their own hardware in collaboration with our experienced staff. P.E. Guerin also offers plating and refinishing services. Clients with qualifying projects can come see their hand-crafted hardware being made in our historic Greenwich Village, NYC foundry, where P.E. Guerin settled down in 1892.
