Pressure Washing

Pressure Washing vs. Soft Washing in Florida

Published March 20, 2026 by WAHOO! Window Cleaning · 6 min read

High PSI can destroy siding, shingles & stucco. When to soft-wash, when to pressure-wash, and how to tell the difference for your Pensacola home.

Pressure washing and soft washing sound interchangeable — they're not. Pick the wrong method and you'll strip paint off your siding, etch your stucco, or blast granules off your shingles and void your roof warranty. The good news: the rules are simple once you know them.

The 3-second rule

If the surface is hard (concrete, brick pavers, dumpster pads), high-pressure water cleans it. If the surface is soft (vinyl siding, Hardie board, stucco, shingles, screens), you soft-wash with low pressure and biodegradable detergents instead.

Surfaces that need SOFT washing

• Vinyl, Hardie & wood siding
• Stucco and EIFS
• Asphalt shingle and metal roofs
• Window screens and lanai screens
• Painted wood fences and pergolas
• Cedar shake and stained surfaces

Surfaces that handle PRESSURE washing

• Concrete driveways and sidewalks
• Brick pavers (re-sand afterward)
• Pool decks (concrete or paver)
• Dumpster pads, loading docks, garage floors
• Brick walls (medium pressure)

Why high pressure destroys Florida homes

Florida's heat and humidity already stress paint, caulk, and roofing. A 4,000 PSI wand makes it worse fast: it forces water behind siding (mold city), strips the protective film off vinyl (chalky and dull in months), and knocks granules off asphalt shingles (the manufacturer's #1 reason for warranty denial). Soft-washing with sodium hypochlorite plus a surfactant kills mildew and algae at the root — without any of that damage.

Quick checklist before you book anyone

1. Ask which method they use on siding — if the answer is just 'pressure', keep looking
2. Confirm they're insured (not just licensed)
3. Ask if they pre-rinse and protect landscaping
4. Get a flat written quote — not 'per hour'
5. Bundle window cleaning in the same visit and save 10–15%
