What Are the Green Stains on my Siding?

Just like any other regular maintenance project, cleaning the exterior of your home is vital to keep your home looking its best. If it has been a while since you last cleaned the exterior of your home, you may notice some green stains forming on your siding. Although these green stains seemingly appear out of nowhere; the good news is that most of these stains are entirely preventable with regular pressure washing for the exterior of your home. You may be wondering, what are these green stains? Why do they form? How do I prevent them? Keep reading to learn all of these answers from our pressure washing experts at Aarron’s Pressure Washing.

To answer the first question, we will need to dive into a few different explanations. There are a few different types of substances that form on siding that can result in green stains. The two most common are mold and algae. While these two substances may seem similar, the treatments vary depending on which type of unwanted plant that you are dealing with. Vinyl and wood-based sidings are particularly susceptible to mold and algae due to their ability to hold onto dirt and other harmful bacteria. You may also experience green stains on your siding formed from mildew.

Now that we have a better understanding of what the green stains are formed from, it’s time to take a look at why these stains form. If you have lived in the Jacksonville, Florida area long, you know that the air is often humid and hot. Mold, mildew, and algae thrive on Florida’s hot, humid climate as well as natural substances that they can attach to. Wood, for example, is the perfect material for these green substances to flourish in. Water leaking from your gutters also can result in any of these materials attaching to your siding. Without regular cleaning, your home will naturally develop these stains unless preventative action is taken.

​While these pesky green stains are certainly an eyesore, preventing them can be as simple as pressure washing your home’s exterior at least once a year. We recommend looking into a local pressure washing company such as Aarron’s Pressure Washing to make sure that the correct cleaners are applied to treat the substance that has attached to your siding. A credible Jacksonville pressure washing company can also recommend what time of year might be best for cleaning your siding also.

Still not convinced that yearly cleaning is necessary? Left alone, these green stains can become embedded into your siding, resulting in permanent staining. To avoid this, it is best to take care of the issue before it becomes an issue. We hope that you have found this information valuable and continue to consider pressure washing for making your home look great.
