Gutter Whitening
Dupont, WA

Clogged and overflowing gutters can cause a mess that hurts the overall appearance of your home. Over time, the exterior faces of your gutters accumulate grime and algae. Cleaning this off can drastically improve the appearance of your home in Dupont. Our Gutter Whitening is a cosmetic cleaning of the outsides of the gutters and downspouts.

We use a hybrid process for whitening the outside of the gutters on your home. First, we apply a bleach-based product called 30-Seconds Outdoor Cleaner to the exterior faces of the gutters and downspouts and gently scrub grime and algae with a car wash brush. We then rinse everything down with a hose. Though we dilute our solution significantly, we also rinse down the surrounding plant life before and after applying the 30-Seconds Outdoor Cleaner to prevent any damage.

When you pair Gutter Whitening with a Gutter Service, we’ll ensure your gutters are functioning properly and looking great. Call us at (425) 821-3814 for a phone estimate and to schedule gutter whitening service for your home in the Dupont area. Our technician will show up on time and complete the work leaving your home looking fantastic.

Frequently Asked Questions

Can’t I paint my gutters instead?

We don’t recommend painting as a solution for the algae and grime that accumulates on your gutters. Painted gutters are much harder to get fully clean, and they are much more prone to staining. Also, your painter will charge you to clean the outside of the gutters first before painting. Gutter whitening is a complete solution, with instant results. Call (425) 821-3814 for a free estimate for your home in Dupont!

If your gutters still have the original factory paint, we expect white gutters to be brilliantly white after a gutter whitening. In some cases, there may be some faint staining that we cannot eliminate completely. Staining is caused by prolonged overflow and is more common and severe on gutters with after-market paint. Be sure to keep your gutters cleaned inside and out by having one of our techs come to your home in Dupont on a regular schedule

We expect a marked improvement in the aesthetic of any house after our Gutter Whitening process, regardless of gutter color. Even if your gutters aren’t white, our Gutter Whitening process will kill any algae and wash away the dirt and grime leaving your home’s appearance refreshed. Our technicians show up happy to help you get your gutters clean. Call (425) 821-3814 for a free estimate for your home in Dupont!

We are always happy to assess creative cleaning opportunities at your home in Dupont. This process has been successful in cleaning algae off slippery decks or even dirty patches of siding.

We will need access to water from your outdoor faucets in order to do the gutter whitening service. Please make sure the water is turned on to the house. If you won’t be home, please unlock your gates so we can get all around your home.

We’ll call or text on the way to your home in Dupont. You don’t need to be home for outside work, but we’ll knock on the door to greet you either way. We’ll let you know if we have questions for you or if your home could benefit from any additional services. When finished, we will come to the door to chat before we leave. We can answer any other questions you may have, let you know if we encountered anything unusual while we worked, and offer recommendations for a service schedule going forward.

Wilber did a great job on gutter cleaning and roof cleaning service. He was thorough and efficient. We had lots of debris and branches on roof and gutter from the storm, which Wilber cleaned up very neatly. He also removed stains from our skylights making it bright and clean. Thank you for your service.

We've used AA to clean out roof and gutters twice now and both times were great. They text ahead when the tech is on the way as well as a small bio and a picture. I really appreciate the on their way text and a picture so I know who to expect. Very polite, professional, and they do great work!

We have been subscribers for three years and have had five cleanings so far, with three different technicians visiting our home. This time, Vincent came, and I was truly impressed by his work. He was incredibly thorough in cleaning the gutters and was the first to recommend a clog prevention device. He also put great effort into the moss treatment, ensuring it was done with care. Every question I had was answered professionally, and he made sure to clean up all the fallen branches and leaves, leaving everything spotless. What stood out the most to me was his dedication—he worked as if he were taking care of his own home. I deeply appreciate his effort and attention to detail. If possible, I would love to have Vincent as our regular technician moving forward. Thank you so much!

We had two incredible technicians work on our house for roof, gutter and skylight cleaning--Jesus and Darrell. They provided the utmost in white glove service--on time, professional, and exceedingly efficient service. After they finished the job they cleaned up every well including the siding and sidewalks. They clearly had the expertise, equipment, supplies, and work ethic to do the job very well! We would (and have already to several of our neighbors) recommend AA Window and Gutter Cleaning!

Kristian was my technician this visit and he did an excellent job, communicating clearly what he did, doing a thorough removal of the moss on the roof and clearing out of the gutters, even going beyond what he had to by realigning one of them. He also took great care in clearing out the debris afterwards. I appreciated his detailed care to his work. Thank you!
