How Often Should You Pressure Wash Your Home
How often should you pressure wash your Greenville home? The answer depends on your siding type, local climate, and surrounding environment.
General Guidelines
- House exterior: once per year
- Driveway and sidewalks: once per year
- Wood deck: once per year before sealing
- Fence: every 1-2 years
- Roof: every 2-3 years (soft wash only)
Factors That Increase Frequency
- Tree coverage — homes shaded by trees get more algae, mold, and leaf stains
- North-facing walls — less sun exposure means more moisture retention and mildew growth
- Humidity — SC's humidity accelerates organic growth on surfaces
- Proximity to roads — homes near busy streets collect more road grime and exhaust residue
- Pollen season — Greenville's spring pollen coats everything and feeds mold growth
Signs Your Home Needs Washing Now
- Green or black streaks on siding, especially on north-facing walls
- Dark stains running down from gutters
- Slippery algae on concrete walkways
- Visible mold or mildew around windows and doors
- Your white siding looks gray or dingy
The Cost of Waiting Too Long
Skipping annual washing is not just cosmetic:
- Mold and mildew can eat into wood trim and siding, causing rot
- Algae on roofs (Gloeocapsa magma) feeds on limestone in shingles and shortens roof life
- Stained concrete becomes permanently discolored if organic stains set in
- Curb appeal drops — a dirty house can reduce perceived property value by 5-10%
Build a Washing Schedule
We recommend Greenville homeowners schedule annual washing in spring or early fall:
- Spring — removes winter grime, pollen, and mildew before summer entertaining
- Fall — clears summer buildup before winter weather sets in
