Vault light restoration The specialized repair and preservation of historic glass lenses set in cast-iron sidewalk frames, historically used to light building basements.
Vault lights are prominent, historic architectural features commonly found in the sidewalks of SoHo and TriBeCa. Because these panels double as the walking surface, property owners are responsible for keeping them structurally sound to prevent basement water leaks and pedestrian injuries. Restoring them is a highly detailed technical process that involves casting custom iron frames, installing matching glass prisms, and sealing the assemblies to meet current pedestrian weight-bearing standards under LPC oversight.
