Allyson explains the process of determining whether hardwood floors can be refinished. By checking the wear layer above the tongue and groove planks, you can see if there is enough wood to sand down and refinish the floors. It is important to consider the type of flooring you have, as hardwood floors can typically be refinished multiple times, while engineered hardwood may only be refinished once or twice. Additionally, the color of the floors may be difficult to change when refinishing, so it's important to love the current color. In conclusion, the best way to determine if your floors can be refinished is to check the wear layer and consider the age and type of flooring you have.
