How much does pressure washing cost in Nashville?
| Service | Typical Nashville range | Priced by |

| House washing (soft wash) | $250–$600 | Sq ft & stories |

Soft washing vs. pressure washing: what's the difference?
| Soft Washing | High-Pressure Washing | |
|---|---|---|
| How it works | Solution kills growth, then rinses | Force blasts the surface |
| Pressure at surface | Low (under 500 PSI) | High (1,300–3,000+ PSI) |
| Siding & roofs | Safe / recommended | Risky |
| Concrete & driveways | Underpowered alone | Correct tool |
| How long results last | Longer (growth killed) | Shorter (regrows) |
Is pressure washing safe for your roof?
Soft washing a roof kills the algae, moss, and lichen at the root and restores the roof's color without touching the granules — which is why it's the only method Southern Solution uses on roofs.
Is soft washing safe for vinyl, Hardie, and stucco siding?
Delicate surfaces like stucco and EIFS are the least forgiving: too much pressure can force water behind the finish and cause expensive moisture damage. This is where hiring a company that understands the chemistry — not just the machine — protects your investment.

Pressure washing in Nashville: FAQ
How much does pressure washing cost in Nashville?
Pressure washing in Nashville generally runs from about $150 to $700 or more depending on the service. House washing typically costs $250 to $600, while concrete and driveway cleaning runs roughly $200 to $700, based on square footage, surface type, and how much buildup is present.
What is the difference between soft washing and pressure washing?
Soft washing uses a low-pressure application of a cleaning solution that kills algae and mildew and then rinses it away, while pressure washing relies on high-force water, commonly 1,300 to 3,000+ PSI. Soft washing is the correct method for siding and roofs; pressure washing is best reserved for hard surfaces like concrete.
Can you pressure wash a shingle roof?
No, you should not pressure wash an asphalt shingle roof because high pressure removes the protective granules from the shingles. The Asphalt Roofing Manufacturers Association recommends a low-pressure soft wash instead, which safely kills the algae causing black streaks without damaging the roof.
How often should I have my house washed in Tennessee?
Most Middle Tennessee homes benefit from a house wash every 12 to 24 months. Humid summers speed up algae and mildew growth, so shaded and north-facing walls often need cleaning sooner than sun-exposed sides.
Do I need to be home for a house washing service?
No, you do not need to be home. As long as there is access to a working water spigot and all windows and doors are closed, the service can be completed while you are away.
Does pressure washing damage siding?
High pressure can damage siding by forcing water behind it and stripping oxidized finishes unevenly. On Hardie board, pressure above roughly 1,500 PSI can chip the finish and void the manufacturer's warranty, which is why a low-pressure soft wash is the safer choice.
