Sun-Fade & Mold: How Atlanta’s Climate Affects Your Home’s Exterior Paint
Posted on July 8, 2025
Through the Atlanta area, summer brings a time of intense sun, high humidity, and frequent afternoon storms. Unfortunately, this combination can not only get in the way of your warm weather plans, but can take a serious toll on your home’s exterior paint. If your siding begins looking faded, stained, or streaky, it’s not just cosmetic. It could be a sign that your paint is no longer protecting your home the way it should.
At CertaPro Painters® of East Metro Atlanta, we’ve seen firsthand how Georgia’s climate can wear down even high-quality paint. Here are two of the biggest culprits of exterior paint damage:
1. Sun Fade
The Atlanta area’s long, hot summers bring strong UV rays that break down the pigments within exterior paint, especially if it’s a darker or more saturated color. South and west facing sides of homes often show fading first. We recommend a professional repaint of fading surfaces with UV-resistant paints.
2. Mold & Mildew Growth
Humidity levels can often get over 70%, accompanied by frequent rainfall, in Snellville. This moisture can cling to siding and trim, creating the perfect environment for mold, mildew, and algae to grow. These organisms feed on paint binders, which can lead to staining, peeling, and even wood damage if left untreated. Proper surface prep, such as power washing, and mold-inhibiting primers are key to painting exteriors in Atlanta’s summer climate.
