Hello, We had an existing pre-finished maple floor in our house made by Siberian and in the color of saddle, which is a medium to dark brown stain. We tore out carpet on the main floor and put in the same wood, 4 years later. Where the old wood ends, the new wood continues. The new wood is a good shade lighter. My question is will even stained wood age or darken over time to become closer to the original installation or does stained wood not darken? I have not been able to find an answer to this question anywhere. Thanks
