Olde Good Things and Old Wood Workshop are two websites that sell antique and salvaged wooden doors. While eBay and Craigslist are other online sources for antique doors, the Dwell.com's publishes a comprehensive Lost and Found list of salvage yards located throughout the country.
Antique paneled doors, barn doors and doors with elaborate glass work or ornamentation are common finds in antique salvage yards. Cost varies depending on the year of the door, the intricacy of the woodwork, and how much refurbishing the buyer needs to do in order to repurpose the door. The price for antique doors runs from several hundred to several thousand dollars.
