Pressure Washing repair in Orlando, FL

Verified against official sources · Updated 2026-07-06

Thinking about a pressure washing repair in the Orlando area? Here's what actually matters — permit rules for Orange County and the City of Orlando, plus the mistakes and code requirements that trip up homeowners, sourced from manufacturer manuals and the Florida Building Code.

Do you need a permit?

It depends on the exact scope. Orange County and the City of Orlando require permits for more than most homeowners expect — and the rules change. Check the county's official "Do I Need a Permit?" page or call your local building department before starting work.

Key facts before you start

Tip colors are spec, not preference (SIMPSON manual): red 0-deg is for unpainted metal/concrete only and will gouge wood, siding, and stucco; white 40-deg is the ONLY tip for painted stucco, vinyl, and painted siding; black low-pressure tip for soap. Keep the nozzle ~4 ft from siding.
PSI by surface: concrete driveways/pool decks take 2,500-3,000+ PSI (use a surface-cleaner attachment for even results); vinyl siding max 2,400 PSI with a 40-deg tip (Georgia-Pacific spec, 1,500 min); stucco needs a wide flat-jet at 8-20 in distance and a tap-test first for loose/drummy render (Karcher) -- never pressure-wash window screens or old single-pane glazing.
Florida green/black staining is live mildew/algae, not dirt: kill it with a sodium-hypochlorite soft-wash solution (GP's mildew mix: 1 qt 5% sodium hypochlorite + 2/3 cup TSP + 1/3 cup detergent in 3 qt water) with dwell time, then low-pressure rinse; raw pressure alone smears spores, regrows in weeks, and etches stucco.
Never spray UPWARD or into openings: water driven up behind siding laps, into soffit vents, window seals, or the stucco weep screed at the foundation gets trapped and rots the wall -- the weep screed exists to drain water OUT (FBC Residential R703.7.2.1); hold the wand at eye level, work top-down.
Never use a pressure washer from a ladder -- the spray gun's reactive kickback force causes falls (verbatim SIMPSON manual warning); use an extension wand or soft-wash from the ground for second-story work.
Spray at electrical receptacles, switches, fixtures, or anything on a circuit can cause fatal shock -- direct spray away and never clean electrically operated devices even when unplugged (SIMPSON DANGER notice); plug electric washers only into GFCI-protected outlets, and treat any skin hit by the jet as an injection injury needing medical care (CDC).
