How Often Should You Pressure Wash Your Home in Atlanta?

Atlanta's climate creates the perfect conditions for exterior buildup. High humidity, abundant tree cover, and a long pollen season mean that algae, mold, mildew, and pollen accumulate on every exterior surface of your home — faster than in most other U.S. cities.

Neglecting regular cleaning doesn't just hurt curb appeal. It shortens the life of your siding, roof, and driveway, and can lead to expensive repairs down the line.

House Exterior (Siding, Brick, Stucco)

• *Every 1–2 years**

Your home's siding is constantly exposed to Georgia's elements. Green algae and black mold streaks are the most common issues, especially on north-facing walls that receive less sun. Soft washing is the recommended method — it kills the organisms at the root and keeps surfaces clean longer than pressure washing alone.

• *Signs it's time now:**
• Green or black discoloration on siding
• Visible dirt or spider webs in corners
• Oxidation (chalky white film on painted surfaces)

Driveway, Patio & Sidewalks

• *Every 1–2 years**

Concrete surfaces are porous, which means they absorb oil, tire marks, and organic material. In Atlanta, the spring pollen season leaves a thick yellow layer that bonds to concrete if left untreated. High-pressure washing restores the original color and eliminates slip hazards.

• *Signs it's time now:**
• Visible staining, oil spots, or tire marks
• Green or black growth in cracks
• Surface feels slippery when wet

Roof

• *Every 2–3 years**

Those black streaks running down your roof shingles are not dirt — they're a living bacteria called Gloeocapsa Magma that feeds on your shingles. Left untreated, it reduces your roof's reflectivity and significantly shortens its lifespan. Soft washing (low-pressure with specialized solution) is the only safe and effective method.

• *Important:** Pressure washing a roof with high pressure voids most shingle warranties and causes premature granule loss.

• *Signs it's time now:**
• Dark streaks running vertically down shingles
• Visible moss or lichen growth
• Shingles look darker on one side

Wood & Composite Decks

• *Every 1–2 years**

Atlanta's rainy summers cause wood decks to gray and develop mold quickly. Annual cleaning removes mold spores and prepares the surface for sealing or staining, which extends the life of the wood dramatically.

• *Signs it's time now:**
• Gray, weathered appearance
• Soft or spongy spots (could indicate rot)
• Visible mold or mildew between boards

Gutters

• *2 times per year (spring and fall)**

Gutters are often overlooked but critically important. Atlanta's tree canopy — especially pine, oak, and sweetgum — drops needles, seeds, and leaves that clog gutters quickly. Clogged gutters lead to water backing up under your roof, foundation erosion, and basement flooding.

• *Spring cleaning:** Removes winter debris before heavy rain season.
• *Fall cleaning:** Removes fallen leaves before winter.

Windows

• *1–2 times per year**

Atlanta's pollen season (one of the worst in the nation) coats windows with a yellow film that's difficult to remove without professional equipment. Streak-free window cleaning dramatically improves your home's appearance and lets in more natural light.

• *Regular exterior cleaning costs a fraction of these repairs.** A professional soft wash and pressure wash package for a typical Atlanta home runs $250–$600 — a smart investment in your property.

• February–March: Pre-pollen soft wash (get ahead of the season)
• April–May: Post-pollen driveway and window cleaning
• June–August: Deck and fence maintenance, gutter check
• October–November: Fall gutter cleaning, pre-winter roof check
• December–January: Great time for driveway and hardscape cleaning
