Many years ago i had a home burn down, and i also lost my guns. Mostly they were smoke damaged, with the stocks blackened, also the blueing was no longer perfect. The fire dept put a lot of water on them and that didn't help either.
In -----> MY <----- case, i replaced or refinished the stocks and kept them. On the centerfires, i handloaded a light load and worked my way back up to my old hunting loads. I kept a carefull eye on everything for quite a while, but all of them turned out fine.
I'd "AT LEAST" get them imspected if you don't know what to look for...
