To achieve a uniform look, the newly installed sections, along with the existing hardwood floors, must be sanded and refinished together. This process involves carefully removing the old finish from your existing floors and preparing the new wood. By sanding both areas at the same time, any height differences or minor imperfections are smoothed out. Once the floors are perfectly prepped, a new stain and protective finish can be applied to the entire surface. This ensures that the newly added wood and the original floors share the exact same color, sheen, and texture, creating a beautiful, unified look that makes it impossible to tell where the old floor ends and the new one begins.
