Salvaged wood is a great option for green flooring. With a salvaged floor you are getting true character — not fake hand scraping or nail holes. You are reusing flooring, so there's less labor and shipping involved, and no virgin lumber is used. Installing salvaged floors does often involve more labor onsite, though. Expect 10 percent to 30 percent more time spent on the job to cull unusable boards, pull stray nails, deal with wonky boards and so on. In my opinion it's worth it, though. And remember, using your purchasing power to support your local labor force is one of the most sustainable decisions you can make.
