What is the green stuff on siding? That’s a common question in the south, and you’ve come to the right place for an answer. Let’s break down what the green stuff is, and how to get rid of it to restore the growth-free beauty to your home’s exterior.

Identifying Green Growth on Your House

When you see green on your siding, it’s typically mold, mildew, or algae. It’s very common for houses in Georgia to have green patches from one or all of these substances. Here’s the low-down on what they are and how they are growing.

Mold or mildew

In the south, homeowners are all too familiar with mold and mildew. Sometimes it can even show up on the outside of homes. Mildew is much more common than mold. You’ll see it on the surface of things in warm, humid environments. It’s usually gray or white, and you can wash it off with soap and water.

Mold is more serious. Mold shows up when there is a greater infestation and more colonization of mold spores. It can be green or black—with black being the more toxic of the two. Either can show up on the outside of your house if you have leaks or drips from a gutter, hose, or drainpipe.

Algae

Algae is an organism that grows where there is water or a high level of humidity or moisture. It goes through the process of photosynthesis, which is what gives it the green hue. You’ll find it often in soil, but as the spores blow through the air, they can land and take hold on your siding. You’ll see it as dark, greenish streaks or patches on the outside of your home. Unlike mold, algae is not harmful. It is mostly just a cosmetic issue.

How to Get Rid of the Green Stuff

It might be tempting to try a DIY approach to wash off the mold or algae on your home. When you have the garden hose out anyway, why not spray down the house? There are a few reasons it’s important to make sure you remove the growth the right way. First, you want to make sure you take care of it completely. Any left behind could lead to more growth. Second, you want to make sure you use the right solution, so you are killing the mold, mildew, and algae and not just getting it wet.

Trust a Professional with Your Home’s Exterior

When it comes to the green gunk on your siding, it’s crucial to hire an experienced professional to make it go away. Power washing with a commercial-grade power washer is the best option. A pro will have the right tools, the best equipment, and the most effective products to clean the exterior of your home without damaging the siding or leaving any green stuff behind.
