What are the Black Streaks On My Gutters?

The black streaking you are seeing did not happen overnight. This streaking is the byproduct of airborne contaminants landing on and bonding to your gutters. Our goal in this article is to give you a greater understanding of the following:

  • How the streaking arrived on your gutters.
  • What these contaminants are.
  • Why these contaminants are so difficult to remove.
  • The measures we take to remove these contaminants.
  • How we extend the life of your gutters.
  • Some frequently asked questions.

How did the black streaks get there?

There are several factors causing your gutters to show black streaks. In every case, airborne contaminants travel from surface to surface. They are attracted to the gutters because gutters are made of metal. The metal carries a positive chemical charge, while airborne contaminants carry a negative charge. Like a magnet, these oppositely charged components will bond together on the exterior surface of your gutters.

So what exactly are these black streaks?

This process of attraction is called electrostatic or ionic bonding. By the time the black streaking appears on the outside of the gutters, the airborne bacteria is already chemically bonded to them. Electrostatic bonding is a strong bond between chemicals that is caused by the attraction of ions that are positively and negatively charged. This process results in black streaks appearing on the gutters.

Can you remove the black streaks yourself?

This is extremely difficult to remove. No matter how much scrubbing you do, you cannot break down this bond completely. Household cleansers will not separate chemically bonded contaminants from the gutters. Getting on a ladder in an attempt to hand-scrub each individual section is also a dangerous endeavor. Our gutter scrub process is designed specifically to remove black streaks from gutters. The cleansers we use with our gutter scrub are formulated specifically to break down this electrostatic bonding. Our process will clean and brighten the gutters, bringing them back to life and making them appear as if they never had streaking on them in the first place.

How do you remove the black streaking from gutters?

Our in-field staff applies our specialized brightening agent to your gutters. The brightening agent not only makes the gutters look brand new, but it also protects the surface. The solution in our brightening agent works because, like the gutters, it is also positively charged. Introducing this solution attracts the negatively charged contaminants, causing them to release from the gutters. While the cleansers take effect, your gutters are meticulously scrubbed with a soft bristle brush in twenty-foot sections. Our staff pays great attention to detail and is always certain to scrub 100% of the gutters and downspouts. Everything is rinsed away with fresh water upon completion.

Will the Perfect Gutter Scrub affect your siding?

We recommend our Perfect House Wash with the gutter scrub for further protection. Scrubbing the gutters without washing the house results in streaky siding because the runoff from rinsing the gutters will drip down the sides of the house. By washing the house along with the gutter scrub, you will keep the home and gutters looking great and protected.

How often should you clean your gutters?

To prevent bacteria from bonding to the gutters, homeowners must get a gutter scrub at least once a year. Preventative maintenance is key to preserve the life of your gutters. Your gutters will not only look bad if you leave them untreated, they will also weaken and need replaced prematurely.
