The answer to 'why is my hardwood floor discolored' is that there are several common causes, including excessive sun exposure, moisture damage, and improper cleaning. Discoloration can appear as fading, staining, or a dull, uneven finish.
Sun exposure is a leading cause of hardwood floor discoloration. UV rays can gradually fade and yellow the wood over time. Moisture damage from spills, leaks, or high humidity can also lead to discoloration, warping, and other issues. Improper cleaning with the wrong products or techniques can strip the floor's protective finish and cause dull, uneven spots.
