For small, simple pieces that aren’t antiques, a professional furniture refinisher can usually refinish a piece in two to three hours, while larger pieces—like bed frames and full dining sets—could take several days. Your refinishing professional should be able to give you an estimated timeline for the work before getting started so that you can plan to be without your furniture during the process. Antique furniture might require additional time and take a week or more to refinish, as they require special care to avoid damage.

Yes, refinishing can decrease or even diminish the value of antique furniture, as most collectors look for original finishes to maintain the piece’s historical integrity. Learning how to clean antique wood and carefully restore the finish without stripping it is the best way to maintain the piece’s original value. Either way, it’s best to take it to a professional furniture refinishing and restoration expert rather than attempting a DIY restoration.
