The answer to 'gutter dusty' is that gutters can become dusty and dirty over time due to a buildup of leaves, debris, and environmental pollutants. This can lead to problems like water drainage issues, pests, and even damage to the home's foundation.
Some common causes of dusty gutters include lack of regular cleaning, trees or plants overhanging the gutters, and high winds or storms that blow in dirt and debris. Symptoms of dusty gutters can include water overflowing, stains on the home's exterior, and visible accumulation of debris.
