The right way to clean a Florida house exterior is soft washing: low pressure combined with the correct cleaning solution, not high-pressure blasting. The solution kills algae and mildew at the root while the low pressure protects stucco, paint, and siding. Done correctly, it cleans thoroughly, avoids damage, and keeps the home clean far longer than a pressure wash.
Why soft washing is the correct method
Florida's siding, especially stucco and painted block, cannot take high pressure. Too much force cracks stucco, strips paint, and forces water behind walls, where it causes mold. Soft washing solves the actual problem, living algae and mildew, with chemistry rather than force. It is the method professional crews use on nearly every home exterior here.

What pressure is safe for each surface?
- Stucco: very low pressure only; let the solution do the work.
- Vinyl siding: low pressure; it cleans easily but can be driven with water behind it.
- Painted block and wood: low pressure to avoid stripping the finish.
- Concrete driveways and walkways: higher pressure with a surface cleaner is fine, this is the exception.
What is the correct step-by-step process?
- Protect landscaping. Wet down and, where needed, cover plants before applying any solution.
- Apply the cleaning solution at low pressure, working bottom to top to avoid streaks.
- Let it dwell so it kills algae, mold, and mildew, do not let it dry.
- Rinse top to bottom at low pressure for an even, clean finish.
- Detail soffits, eaves, window frames, and the foundation line.
What should you never do?
- Never pressure wash stucco or a roof, the damage is expensive and often permanent.
- Never skip plant protection, undiluted solution can burn landscaping.
- Never clean in direct hot sun, the solution dries too fast to work and can streak.
- Never ignore the roof and gutters, streaks there wash back down onto clean walls.
If someone approaches your stucco with a turbo nozzle, stop them. The right tool for a house is chemistry and low pressure, not raw force.
Why Florida homes need a local approach
Generic, northern-state cleaning advice often assumes vinyl siding and hard water, not our stucco, salt air, and aggressive Gloeocapsa magma algae. A crew that knows the Treasure Coast adjusts the solution strength for humidity and coastal exposure, which is why homes in Vero Beach and across Indian River County get better, longer-lasting results from a local pro.
How are different siding materials handled?
The right technique adapts to the material. Stucco is porous and holds algae in its texture, so it needs a properly dwelling solution and a gentle rinse, never a turbo nozzle. Vinyl cleans easily but must be rinsed carefully so water is not driven behind the panels. Painted block and Hardie board respond well to low pressure and the right solution strength, while failing or chalky paint has to be treated gently to avoid stripping it further. A crew that identifies the material first and adjusts accordingly gets a clean, damage-free result every time.
Why hire a local crew over a national chain?
Florida exteriors have quirks that reward local knowledge:
- Salt air that requires more frequent rinsing near the coast.
- Aggressive algae that needs the right algaecide strength for our humidity.
- Stucco and tile that generic pressure-washing scripts get wrong.
- HOA expectations specific to Treasure Coast communities.
A local team has cleaned thousands of homes in these exact conditions and tailors the method to what your house and neighborhood actually need.
How do pros protect your landscaping?
Plant protection is part of doing the job correctly, not an afterthought. Before any solution is applied, crews thoroughly wet down the surrounding beds and lawn so foliage is saturated and less able to absorb product, and delicate or prized plants may be covered. During and after the wash, landscaping is rinsed again to dilute anything that lands on it. This careful handling is a major reason to hire a trained, insured team rather than experiment yourself, since an undiluted solution applied carelessly can scorch the very landscaping that frames your home.
