Pressure Washing Nashville & Middle Tennessee

Soft washing uses low pressure (under 100 PSI) combined with manufacturer-approved detergents to kill algae, mold, and mildew at the root. Unlike high-pressure washing which can strip granules from shingles and force water behind siding, soft washing is the only method approved by asphalt shingle manufacturers like GAF, Owens Corning, and CertainTeed. Results typically last 3–5 years versus 6–12 months for pressure washing alone.

Typical house washing in Middle Tennessee ranges from $250 to $600 depending on size and complexity. Concrete cleaning runs $200–$700, and soft-wash roof cleaning runs $0.15–$0.35 per square foot.

Those black streaks are caused by a blue-green algae called Gloeocapsa magma. It feeds on the limestone filler in asphalt shingles and spreads across your roof, trapping heat and shortening shingle life. The algae thrives in humid climates like Middle Tennessee and spreads from roof to roof through airborne spores... which is why entire neighborhoods often get streaks at the same time. Only a manufacturer-approved soft wash kills it at the root. Pressure washing will damage shingles without removing the underlying algae colonies.

Middle Tennessee's humid climate accelerates algae, mold, and mildew growth. Most homes benefit from house washing every 1–2 years, shingle roofs typically need soft washing every 3–5 years, and concrete driveways show dirt faster and look best when cleaned annually. If you can see visible green, black, or gray staining from the street, your property is overdue for service.

Yes. Our soft washing process uses biodegradable, eco-friendly detergents that break down safely after rinsing. We thoroughly saturate surrounding plants and landscaping with water before and after treatment as a protective measure, and we follow all EPA water safety guidelines. Pets and family should stay indoors during active cleaning, but surfaces are safe to use once the area is dry... typically 1–2 hours after we finish.

Results depend on the service and your environment. Our soft-wash house washing typically keeps siding clean for 1–2 years before visible regrowth. Soft-wash roof cleaning lasts 3–5 years and actively extends shingle life. Concrete cleaning generally looks fresh for 1–2 years depending on traffic, shade, and tree coverage. Every service comes with a warranty... if algae returns early, we return and re-treat at no cost.

Pressure washing uses high-pressure water to remove dirt. Power washing adds heated water to high pressure... some contractors use it for heavy commercial grease work. Soft washing uses much lower pressure (under 100 PSI) combined with specialized biodegradable cleaners that kill algae and mildew at the root, making it the only safe method for roofs, painted siding, stucco, wood, and other delicate surfaces. Using the wrong method on the wrong surface is the #1 cause of property damage from DIY and inexperienced washers.

No. As long as we have access to an outdoor water spigot and the areas being cleaned, we can complete the job while you're at work or running errands. Before we arrive, please secure pets indoors, close all windows, and move vehicles away from the wash zones. We'll text you when we arrive, when we finish, and send before-and-after photos of the completed work so you can verify results without being on site.

Improper technique can absolutely cause damage. Common failures from inexperienced crews include etched concrete, stripped paint, cracked mortar joints, water forced behind vinyl siding, and loss of shingle granules. That's why we match the method to the surface: commercial-grade pressure washing with professional surface cleaners on concrete, soft-wash at low pressure on siding and roofs, and gentle rinsing on delicate substrates. Every Southern Solution technician is trained on manufacturer-approved methods for each surface type, and all work is backed by our satisfaction guarantee.

Exterior cleaning can be performed year-round as long as temperatures stay consistently above 40°F during the cleaning window. Spring (March–May) is our busiest season... homeowners remove winter grime before outdoor entertaining and boost curb appeal. Fall (September–November) is also excellent for removing summer algae buildup before holiday season and winter. We schedule commercial work through all four seasons.

Yes. Southern Solution is insured and follows OSHA safety practices. We are a veteran-owned business and carry general liability coverage.

Yes. Our house washing comes with a 2-Year Green-Free Warranty, and soft-wash roof cleaning includes a 3–5 Year Warranty depending on your roof condition and tree coverage.
