The answer to 'gutter greasy' is that gutters can become greasy and dirty over time due to a buildup of debris, leaves, and other organic matter. This can lead to clogged downspouts, water overflow, and even pest infestations. Common symptoms include visible grease and grime on the gutter surfaces, as well as water backing up and overflowing during rainstorms.
The best solution is to regularly clean and maintain your gutters to prevent this buildup. This can often be done as a DIY project, but for heavily soiled or hard-to-reach gutters, it's best to hire a professional gutter cleaning service. They have the right tools and equipment to safely and effectively clean your gutters and ensure proper drainage.
