Every Florida homeowner eventually rents a pressure washer, and the first ten minutes are genuinely satisfying — the driveway comes up two shades brighter and it feels like a solved problem. The trouble starts when that same wand gets pointed at everything else on the property.
Here's the thing most people don't realize: professional cleaning is rarely about pressure. It's about chemistry and dwell time. The right detergent, given a few minutes to work, releases algae and mildew at the root. High pressure just blasts the surface layer off — it looks clean for a few months, then comes back faster, because the organism was never actually killed.
Start with what you genuinely can pressure wash. Concrete driveways, sidewalks, and pavers handle it fine, and a surface cleaner attachment gives a far more even result than waving a wand back and forth, which leaves the striping you see all over neighborhoods here.
Now the list to keep the wand away from. Tile and shingle roofs are first and most important. High pressure cracks tile, breaks the seal between shingles, and strips the granules that are the entire UV protection of an asphalt roof. Roofs get soft washed — low pressure, correct detergent, patience. Pressure washing a roof can void the warranty and, in the worst cases we've been called out to see, causes leaks that cost more than the whole exterior job.
Painted siding and stucco come next. Enough pressure will force water behind the coating and under the substrate, and on stucco it will erode the texture and open hairline cracks into real ones. On older wood siding it can strip the surface fibers and leave a furry texture that never takes paint properly again. All of it should be washed at low pressure with the detergent doing the work.
Window seals and screens are easy to wreck and easy to forget. A direct hit will force water past the glazing seal into the frame, and it'll punch straight through a lanai screen. Soffit vents are similar — spraying upward into them drives water directly into your attic.
Wood decks are the one people regret most. Full pressure raises the grain, gouges softwood, and leaves permanent wand marks in a fan pattern across the boards. Decks want a cleaner, a brightener, and a light touch — then they're ready to stain. A gouged deck can't be undone.
Also worth protecting: your landscaping. Cleaning detergents will burn plants. Soaking the beds with plain water before you start and rinsing them after is standard practice, and skipping it is how people lose a hedge line to a job that was supposed to improve the property.
One final note on timing. If you're planning an exterior repaint, the wash is part of the paint job, not a separate purchase — and it needs to be done properly, because paint bonds to what's underneath it. Getting the house blasted at full pressure a month before painting can actively make the repaint worse.
