How can I tell if my wood floor needs refinishing?

Wood floor refinishing needs to be carried out when you start noticing scratches, stains, dents or splinters in your flooring which cannot be removed by your usual cleaning methods. Not only can scratches and stains look unsightly, but splinters can be dangerous, especially if you have children or walk around without shoes on. Other signs that your wood floor needs refinishing would be if it is looking dull. As this happens overtime, you may need to look at flooring that has been under furniture to notice the difference.
