Pollen Season Wash Timing Guide
If you have lived in Jacksonville through a spring, you know the ritual. Late February rolls around, the live oaks start dropping their catkins, and within weeks everything you own — cars, patio furniture, siding, the pool deck — is coated in a fine yellow-green film. Pine pollen follows in April and May, sometimes thick enough to see drifting in the air. It is one of the most distinctive things about spring in Northeast Florida, and it has real consequences for when you should pressure wash your home.
The short version: do not pay for a house wash in the middle of pollen season. The film will be back within days, and you will have spent good money for about a week of clean siding. The right move is to wait until the pollen drops — usually late May into June — and then wash once, properly. Here is the full picture.

When Is Pollen Season in Jacksonville?
Jacksonville's pollen season runs roughly from late February through May, but it comes in waves from different trees. Live oaks — the big sprawling trees that define so many Jacksonville neighborhoods, from Riverside to Mandarin — release their pollen and drop stringy catkins mostly in March and April. You will know it is happening: the catkins pile up in gutters, clog pool skimmers, and mat down on driveways in soggy brown clumps after rain.
Pine pollen typically peaks a little later, in April and May. It is the fine yellow dust that coats cars overnight and leaves yellow rings in puddles and pools. Unlike oak catkins, which are visible debris, pine pollen is a true film — it settles on every horizontal and vertical surface and bonds lightly with moisture.
Exact timing shifts year to year with the weather. A warm February brings everything early; a wet spring can wash pollen out of the air in bursts, only for it to return. As a rule of thumb, if your car is turning yellow overnight, pollen season is still on — and it is not wash time yet.

Why Washing During Pollen Season Wastes Your Money
This is the mistake we see every spring: a homeowner books a house wash in mid-April because the siding looks terrible, the crew does a beautiful job, and by the following weekend the north wall is yellow-green again. The wash was not defective — the timing was.
Pollen film resettles fast. On a heavy pollen day, a freshly washed surface can show visible film within 48 to 72 hours. You paid for a 12-to-24-month result and got about a week of it. No reputable company should sell you a full house wash at peak pollen without warning you about this first — if a company is happy to take your money in April without mentioning it, that tells you something about the company.
There is one exception: if you are dealing with an HOA violation letter or listing the house for sale, sometimes you cannot wait. In that case, wash — but go in knowing it is a cosmetic reset with a short shelf life, not the long-lasting clean you would get in June.

The Right Timing: Wait for the Drop
The sweet spot for a Jacksonville house wash is late May through June, after the pine pollen has finished. How do you know it is over? The signs are unmistakable once you know to look: cars stay clean for more than a day, the yellow rings stop forming in the pool, and the oak catkins have finished falling and been rained away.
Washing right after pollen season ends has a compounding benefit. Pollen film is not just ugly — it is organic matter, and organic matter is food and scaffolding for mold and mildew. The film that settles in spring gives summer mold spores something to grip. A thorough wash in June removes the pollen layer before Jacksonville's brutal summer humidity turns it into a mold farm. Homeowners who wash in June consistently find their siding stays clean longer than those who wash at any other time of year.
For most Jacksonville homes, one well-timed wash per year — post-pollen, early summer — is the ideal cadence. Heavily shaded lots under big oaks may still want a second pass in fall, but the June wash is the one that matters most.

What Pollen Does Beyond Looking Bad
The yellow film is the visible part. Underneath, pollen season does quiet damage that most homeowners never connect to the trees:
- Gutters choke on oak catkins. Those stringy tassels mat together when wet and form dense plugs, especially at downspout elbows. A gutter full of catkins cannot handle Jacksonville's summer downpours, which is how fascia boards rot and water finds its way behind siding.
- Pool systems strain. Pollen clogs skimmer baskets and loads up filters fast. If your pool equipment is working overtime every April, the pollen — not the equipment — is usually the problem.
- Allergies spike indoors and out. Pollen tracked in on shoes and blown through window screens keeps allergy symptoms going for weeks. A clean exterior, clean walkways, and clean window frames genuinely reduce the pollen load around entry points.
- Mold gets a head start. As noted above, settled pollen is a growth medium. The black streaks on your roof and the green film on the north wall both establish faster on top of a pollen layer.
A post-season wash addresses all of this at once: siding, gutters flushed clear, walkways, and pool deck. It is the single highest-value exterior service a Jacksonville homeowner can schedule each year.

The Ideal Annual Schedule for Jacksonville Homes
If you want a simple calendar that actually fits Northeast Florida, here it is:
- Late May / June: the big one. Full house wash (soft wash), gutter cleanout, driveway and walkway cleaning. Done after pollen season, before the worst summer humidity.
- September / October: optional touch-up. If you are in an HOA community like Nocatee or Ponte Vedra that sends compliance letters, a fall rinse keeps you ahead of them. Also a good time for paver sealing — the sealer cures well in warm, drier fall weather.
- As needed: roof soft wash every 2 to 3 years (those black streaks are gloeocapsa magma algae, and they do not care about pollen season), deck and fence cleaning when the gray sets in.
The homeowners who follow this rhythm spend less over time than the ones who wash reactively whenever things look bad — because each wash lasts longer when it is timed right.
