How Often Should You Pressure Wash Your Alpharetta Home?
Your home faces humid summers, heavy spring pollen, and plenty of shade from mature trees. That mix invites algae, mildew, and grime. Most Alpharetta houses benefit from exterior cleaning every 12 to 24 months, with some areas needing attention sooner. For delicate surfaces like siding, stucco, and painted trim, a professional soft washing approach is the safe way to keep curb appeal high without risking damage.
What Really Determines Your House Washing Frequency
Every property is different, even on the same street. Moisture, shade, and airflow are the big drivers. Homes near wooded corridors like the Big Creek Greenway or in tree‑dense neighborhoods such as Windward and Crooked Creek often see faster organic growth on north and east walls.
Shade, Trees, and Moisture
Shaded walls stay damp longer after rain or irrigation. That moisture feeds algae and mildew, especially on vinyl, painted wood, and stucco. If your lot backs to a stand of pines or oaks, expect to clean more often than a sun‑drenched corner lot near Avalon or Downtown Alpharetta.
Surface Type and Age
Newer, high‑quality paint and modern vinyl resist buildup better than older finishes. Porous materials like unsealed brick and pavers pick up grime faster. Roof shingles with visible black streaks from algae also affect how often you wash adjoining walls and gutters.
Weather and Pollen
Spring pollen coats everything in a yellow‑green hue, then summer humidity locks it in. After a stormy stretch, moisture leaves behind dark trails and spotting. If you notice streaks reappearing within weeks of a rinse, your timetable should shift to the shorter end of the range.
Clear Signs It’s Time To Wash
- Green film or black streaks on siding, fascia, or the north‑facing walls
- Slippery steps or walkways and a dingy look around shaded entries
- Window sills or trim that stay dirty even after rain
- Spider webs, wasp residue, or soot buildup under eaves and porch ceilings
- The driveway looks gray and blotchy even after sweeping
A Simple Seasonal Schedule For Alpharetta Homeowners
Use this easy rhythm to keep up with the weather here while avoiding over‑cleaning.
- Late March to May: After the heavy pollen drop, schedule a whole‑house cleaning so spring color pops. Many residents tie this to landscape refreshes.
- Mid‑Summer: Walk the north and shaded sides. If algae is back, spot clean sooner rather than later.
- September to November: Clear stains made worse by leaf litter and late‑summer storms. This is also a great time to pair siding care with roof cleaning.
- Winter: Visual check after long rains. With mild winters, buildup can continue on shaded walls.
If you prefer one main visit, choose a post‑pollen spring service. That timing keeps your exterior looking its best for most of the year and aligns with landscaping, window cleaning, and outdoor entertaining.

Soft Washing vs. High Pressure: What’s Best For Your Home
High pressure is great for rugged concrete, but it can scar siding, etch stucco, and push water behind trim. A professional soft wash uses low pressure with targeted detergents to lift and rinse contaminants safely. It is ideal for painted exteriors, Hardie siding, and roofs with algae streaks. If you’ve spotted oxidation or chalking on older paint, soft washing helps clean without accelerating wear.
Think of it like washing a new car. You wouldn’t blast the clear coat. You’d loosen and rinse the grime gently. The same idea protects your home’s finish while restoring a fresh, even look. When a full exterior refresh is due, book trusted soft washing so the clean lasts and the surface stays sound.
Room‑By‑Room Timelines Around The Exterior
Different areas age at different speeds. Here’s how to think about it so you stay ahead of trouble.
Siding and Trim
Most homes do well with a 12–24 month cadence. Shaded, wooded lots often need 12–18 months. Watch porch ceilings and soffits; if they look dusty or gray, the walls usually aren’t far behind. Don’t let algae sit through peak summer humidity because it can stain and harden, especially on textured finishes.
Roof
Those black roof streaks are algae feeding on shingles. Treating them with a roof‑safe soft wash prevents premature wear and refreshes the whole look of the house. Pair your roof care with fall or spring siding service to minimize ladder traffic and repeat setup.
Driveway and Walkways
Concrete takes abuse from tires, shade, and runoff. Many homeowners refresh driveways annually or every 18 months. For a deeper look at curb appeal benefits, see this post on driveway pressure washing.
When Nature Speeds Up The Timetable In Alpharetta
Homes near Lake Windward or along creek corridors collect more moisture overnight. North‑facing walls on lots lined with tall pines hold dew longer. If you live under dense canopy or back to natural areas, plan for shorter intervals and quicker spot cleanings on shady sides. North‑facing and fully shaded walls almost always need attention first.
Maintenance Made Simple: A Practical Plan
Use the seasons to your advantage. Book a whole‑house service in late spring after pollen, then a quick check in late summer for shade‑side touch‑ups. In the fall, combine siding care with gutter and roof attention so your exterior is ready for holiday hosting and winter rains. This approach keeps curb appeal steady and helps protect paint, sealants, and caulking.
