If you moved here from somewhere with actual seasons, throw out whatever cleaning schedule you used up north. It does not apply.
Up north, surfaces get a few months a year to dry out and kill off whatever is growing on them. In St. Petersburg they get maybe a few weeks. Everything else is humidity, rain, and salt.
So here is the schedule that actually works here: the house exterior once a year, flat surfaces like the driveway, walkways, and pool deck every six to twelve months, and the pool cage once a year. Waterfront or heavily shaded? Move everything to the early end.
Key Takeaways
- House exterior: once a year. Every eight to ten months if you are on the water or under trees.
- Driveway, sidewalks, pool deck: every six to twelve months. Shade pushes it to six.
- Pool cage and screens: once a year.
- Roof: every two to three years, soft wash only.
- The signs it is time: green or black streaks, a chalky dullness on paint, and anything that feels slick when wet.
The Schedule, Surface by Surface
| Surface | How often | Why so often here |
|---|---|---|
| House exterior and siding | Once a year | Humidity and salt feed mildew on stucco, vinyl, and paint all year |
| Driveway | Every 6 to 12 months | Flat, porous concrete collects oil, pollen, and growth |
| Sidewalks and walkways | Every 6 to 12 months | Shaded paths grow slick film fast |
| Pool deck | Every 6 to 12 months | Constant splash plus shade equals a slip hazard |
| Pool cage and screens | Once a year | Cages trap humidity and grow mold on frames and mesh |
| Roof | Every 2 to 3 years | Algae streaks show up faster on shaded north slopes |
Those are starting points. Two things shift them, and I will get to both.
The House: Once a Year, Soft Wash
Why once a year and not less?
Because siding, stucco, and paint all hold moisture in tiny surface pockets. That moisture never fully leaves in our climate, so the mildew never fully stops. Wait two years and you are not cleaning anymore, you are trying to lift staining that has set into the material.
A few things speed it up:
- North facing walls stay damp longest and green up first.
- Salt air leaves a fine film that dulls paint and gives algae something to grip.
- Shade from oaks or a neighbor’s house is worth an extra cleaning every couple of years on its own.
And the method matters as much as the timing. Walls get soft washed, never pressure washed. Our house exterior and siding service page walks through how we approach it.
The Driveway: Every Six to Twelve Months
Concrete is porous and it sits flat. Rain, pollen, oil drips, leaf litter. It all lands there and stays.
Here’s how to figure out your end of the range:
- Tree cover or afternoon shade? Six months.
- Full sun, open lot? You can stretch toward a year.
- Oil drips or rust marks? Sooner. Those set fast and go deep.
The failure mode with driveways is waiting until it looks bad. By then the growth has anchored into the surface and one cleaning will not fully lift it. Our driveway pressure washing page covers what a proper job involves.
Pool Decks and Walkways: The Ones That Hurt People
This is the surface I would push hardest on, and not because of how it looks.
A pool deck combines constant moisture, shade from the cage, and bare feet. Textured pavers and travertine trap growth in every little pit. Six months in, you have a slick film you cannot see but can definitely feel.
Walkways are the same story with shoes instead of bare feet. Entryways and side yards get the most traffic and the least sun.
We treat both with slip safety first. There is more on why in our guide to pressure washing and slip and fall safety, and the pool deck and sidewalk service pages cover the work itself.
Roofs and Screens: The Ones You Forget
Nobody looks at their roof. Nobody looks closely at their cage. Both collect growth quietly until one day the black streaks are obvious from the street.
- Roofs show algae streaks within two or three years, sooner on shaded slopes. Soft wash only. Pressure lifts shingles and kills the warranty.
- Pool cages hold humidity and shade, so mold builds on the frame and the mesh. Once a year keeps them clear and, honestly, makes them last longer.
The Two Things That Change Everything
Water
If you are on the bay, a canal, or the Gulf, salt air is doing work on your house every single day. Move every surface to the early end of its range and pay extra attention to the cage and the pool deck. We wrote a whole post on waterfront and salt air homes because it is that different.
Shade
Big oaks are beautiful and they are the enemy of a clean driveway. Anything under heavy canopy stays damp, grows faster, and needs a twice a year look at the flat surfaces.
Full sun, open lot, no water nearby? You get the long end of every range. A yearly exterior wash is still the safe rhythm.
How to Tell It Is Time
Some signs you see. Some you feel.
You see
- Green, gray, or black streaks on siding, fences, or the roof.
- Dark spotting or fuzz in shaded corners and along the foundation.
- Paint or stucco that looks chalky and faded instead of crisp.
- Rust marks, pollen, or dark growth spreading across concrete.
You feel
- Steps, walkways, or the pool deck are slick when wet.
- A musty smell near shaded walls or the lanai.
- Surfaces that stay damp long after the rain stops.
Any of those means the growth is already active. The point of a schedule is to get there first.
Does a Schedule Actually Pay Off?
Yes, for a boring reason. Algae and mildew are not just ugly. They dig into porous surfaces, hold moisture against your home, and leave staining that no single cleaning fully lifts. A steady rhythm stops the cycle before it starts.
It also protects value, which we get into in whether pressure washing increases property value in St. Petersburg. For the full picture on methods and surfaces, the complete guide to pressure washing in St. Petersburg ties it together.
How We Set a Schedule With You
We do not hand you a script. We walk the property, look at what is shaded, what is near water, and what is already showing growth, then build a rhythm around your actual house.
Because we are two people doing the work ourselves, the person who sets the schedule is the person who shows up for it. That consistency is the whole game with maintenance.
Frequently Asked Questions
How often should I pressure wash my house in Florida?
Plan on a full exterior soft wash once a year. Shaded, waterfront, or under heavy trees? Every eight to ten months.
How often should a driveway be cleaned in St. Petersburg?
Every six to twelve months. Shade and tree cover push it to six. Open, sunny driveways can go closer to a year.
How often should a pool deck be cleaned?
Every six to twelve months, sooner if it stays wet or shaded. The slick film builds fast and it is a real slip risk around bare feet.
How often does a roof need cleaning here?
Most St. Petersburg roofs show algae streaks within two or three years. Soft wash only, never pressure.
Can I just wash everything once a year and be done?
The house, yes. Flat surfaces usually need attention twice a year because they hold moisture and grow slick film faster. Each surface runs on its own clock.
