I know of at least one company in New England who is using these recycled beams in new houses. They are cutting new joints and using them in different parts of the frame.
They could also be used for repairs if the sizes where similar.
Another use, other than as a beam, is to re-mill them into flooring or other use boards and or planks. I've done that with older salvage previous milled beams, and it could be done with hewed beams as well. Jim
