Why is the flooring beneath my area rugs and furniture lighter than the rest of the floor?
All wood flooring is more or less photosensitive, and some species are very sensitive to ultra-violet light. This means the wood reacts to the light it's exposed to by slowly and slightly lightening, or remaining it's original tone if not exposed. It’s important to prevent the sun’s rays from discoloring your floor by shielding it against direct sunlight. However, it’s normal for hardwood floors exposed to even indirect sunlight to darken or lighten after a while, so for consistency, rotate rugs and furniture to equal out the amount of sunlight exposure and variances will eventually fade away.
