Anyone here ever restore wood floors?

[Z]

I didn't personally do the work, but I did refinish my floors - commercial carpet had been glued down ontop of it. They used MANY sanding wheels to get the wood prepped, but it turned out beautifully. This small sample doesn't look bad - but you won't know the full state until all the vinyl is up. It wouldn't hurt to get a quote from a wood floor refinisher / feasibility thoughts.

If the wood is beyond salvaging (relatively unlikely), there are a number of interesting alternatives that mikebw listed. Cork tiles? Perhaps a return to natural (sans-petroleum) linoleum?

Good luck,
