The answer to 'when to clean gutter' is that you should clean your gutters at least once or twice a year, typically in the spring and fall. Gutters can collect leaves, twigs, and other debris over time, which can cause clogs and prevent proper drainage. Cleaning your gutters regularly helps prevent water damage to your home's foundation, walls, and landscaping.
The best time to clean your gutters is in the spring, after the trees have finished shedding their leaves, and in the fall, before the winter weather sets in. This ensures that your gutters are clear and ready to handle the increased rainfall and snowmelt during the changing seasons.
