Salvage yards have always been a great place to find old house parts. These can be recycled as art objects or as replacement parts for older homes, or even to add a touch of charm for doors, banisters, shutters, old sinks, cabinets and bathtubs in new homes. It would be a shame to see them go to waste, but you should also be sure to buy from reputable architectural salvage yards, and always ask where it came from.
