If you own a home anywhere around Sarasota, you’ve probably asked some version of this question standing at the end of your driveway: is it time again already? The honest answer is that Southwest Florida is one of the hardest environments in the country on a home’s exterior — and “how often” depends far more on the surface than on the calendar.
Let’s break it down the way we actually think about it on a job.
Why Southwest Florida is a special case
Three forces gang up on every exterior here. Humidity feeds the blue-green algae that streaks roofs and darkens walls. Salt air off the Gulf and the bays settles on everything, hazing glass and speeding up corrosion and growth. And the sun and summer rain cycle bakes grime into porous concrete and pavers, then washes more onto them.
The result is that a house in Sarasota simply gets dirty faster than the same house would in a drier or cooler climate. A driveway that might go three years up north often wants attention every year here. None of that means anything is wrong with your home — it’s just the trade-off for living somewhere this beautiful.
A realistic schedule, surface by surface
Rather than one number, think in terms of surfaces.
Driveways, sidewalks and pool decks — about once a year
Horizontal concrete and pavers collect the most: foot traffic, tire marks, organic growth in the shaded spots, and a steady film of grime. For most Sarasota homes, an annual pressure wash keeps these looking sharp. Homes under heavy tree cover, or with a north-facing drive that stays damp, often want it a little more often — that green tint at the edges is algae getting a foothold.
Roofs — every few years, and never with pressure
A roof is the surface people wait too long on, usually because they don’t realize the black streaks are alive. That staining is algae, and it should be cleared with a low-pressure soft wash, not a pressure washer, which can crack tile and strip shingle granules. Done properly — killing the growth at the root — roof cleaning lasts far longer than a surface rinse, often a few years. If your roof is visibly streaking, that’s the signal.
Siding, stucco and soffits — every one to two years
Walls don’t get dirty as fast as the ground, but the shaded and north-facing sides grow algae and mildew steadily. A soft wash every year or two keeps stucco and painted surfaces bright without the risk high pressure poses to a finish.
Screen enclosures and pool cages — as needed, gently
Cages trap pollen, mildew and salt. They can be soft washed on the same visit as the walls or roof. High pressure tears screen and loosens frames, so this is always a low-pressure job.
The signs it’s time (before it’s obvious)
You don’t have to track dates. Your house will tell you:
- Green or black at the edges of a driveway, walkway or pool deck.
- Dark streaks running down the roof, especially on the shaded slope.
- A dull film on stucco, or a wall that looks patchy in flat morning light.
- Slippery spots on shaded concrete — that’s algae, and it’s a safety issue as much as a cosmetic one.
- Your windows haze back over within a few weeks of cleaning — a sign of the salt load in your specific location (more on that in why windows film over near the Gulf).
Catching these early matters. Growth that’s cleared quickly comes off easily; growth left for a season digs into the pores of the surface and takes more work — and sometimes leaves a faint ghost behind.
Coastal homes are on a faster clock
Where you live in the area changes the math. A home on Siesta Key, Lido Key or Longboat Key sits directly in the salt spray and will generally want everything done more often than an inland home in Lakewood Ranch. Wooded south-county lots in Osprey and Nokomis trade salt for shade — which brings its own moss and lichen. We tailor the rhythm to the property, not a generic schedule.
The bottom line
For most Sarasota homes: pressure wash the flat hard surfaces once a year, soft wash the walls every year or two, and soft wash the roof every few years or whenever it starts to streak. Adjust up for coastal exposure or heavy shade.
If you’d rather not track it yourself, that’s part of what we do — call or text us and we’ll take a look, tell you honestly what needs doing now and what can wait, and set a rhythm that keeps your home looking its best without over-cleaning it.
