If you live in metro Atlanta, you’ve probably noticed how quickly the exterior of your home can go from clean to grimy. Between our humid summers, heavy pollen, and shady tree cover, dirt and algae build up faster here than in drier climates. So how often should you actually pressure wash your house?
The Short Answer: Once a Year
For most Atlanta-area homes, a professional house washing once per year is the sweet spot. This keeps algae, mildew, dirt, and cobwebs from building up to the point where they stain or damage your siding.
That said, a few factors can change the ideal frequency:
- Lots of shade and trees? You may need a wash every 6–9 months, since shaded surfaces hold moisture and grow algae faster.
- Light-colored siding? Dirt and green streaks show up more easily, so you might want to clean more often for curb appeal.
- Near pollen-heavy areas? Spring pollen season can leave a yellow film that’s worth rinsing off.
Signs It’s Time for a Wash
Don’t just go by the calendar. Walk around your home and look for:
- Green or black streaks on siding (that’s algae and mildew)
- A chalky or dull appearance to your paint
- Spider webs and wasp nests in corners and eaves
- Black “tiger stripes” on your gutters
If you’re spotting any of these, it’s time.
Why Regular Washing Protects Your Investment
Algae and mildew don’t just look bad — they actually feed on organic material in your siding and trap moisture against your home. Over time, that leads to premature aging, discoloration, and even rot. An annual wash is a small cost that protects one of your biggest investments.
A clean exterior isn’t just about looks — it’s preventative maintenance for your home.
Leave It to the Pros
