More importantly, it removes visible staining but leaves the biological organism alive in the pores โ€” regrowth appears within months. **Soft wash kills the organism at the cellular root**, producing results that last 18 to 24 months on Naples stucco versus 3 to 6 months from pressure washing. Gated Community Pre-Registration Naples Pressure Washing is pre-registered with most major Naples and SWFL gated communities. **We coordinate gate access directly โ€” you do not need to call your HOA** or arrange passes. We bring all required licensing, insurance, and COI documentation that HOA management requires. โ“ Frequently Asked QuestionsHouse Washing Results ยท Naples FL How long do house washing results last on Naples stucco?18 to 24 months for most Naples stucco homes in inland locations. Beachfront and coastal homes may need cleaning every 10 to 12 months due to salt air exposure. Gulf-adjacent homes see faster reaccumulation because salt deposits create an adhesion layer that holds airborne biological spores. Is soft wash safe for Naples stucco?Yes. Soft wash at 40 to 80 PSI is specifically appropriate for stucco surfaces. High-pressure washing above 500 PSI on stucco erodes texture, forces water behind the surface, and can cause paint adhesion failure. All of the results on this page were achieved at pressures that protect the stucco integrity. What causes the black streaks on my Naples stucco?Black vertical streaking on Naples stucco originates from algae growth on the soffits above the wall surface. Rain water carries the algae down the wall face creating characteristic vertical streaks. Treating only the wall without treating the soffit source produces only temporary results โ€” we treat both in every job. How much does house washing cost in Naples FL?Most Naples single-story homes start at $399. Two-story and estate homes start at $499. We are consistently 15 to 30 percent less than the competition.
