Northeast Florida home exterior before and after a seasonal soft wash

Best Time to Pressure Wash a Home in NE Florida

August 05, 2026

Short version: you can pressure wash year round in Northeast Florida, and that is genuinely one of the perks of living here. But some months are better than others depending on what you are trying to accomplish.

Northeast Florida does not have a wrong season

In most of the country, exterior cleaning stops when it freezes. Here it does not. Our winters stay mild enough that we work through them, which means you are choosing timing based on results rather than weather windows.

That said, the growth cycle of algae and mildew in our climate is real, and working with it rather than against it gets you a longer lasting clean.

Late winter and early spring: the sweet spot

February through April is our favorite window for a full house wash. Humidity has not peaked yet, pollen season is either about to start or just finishing, and a clean done now carries you into the heaviest growth months looking good.

It is also the right time if you are listing your home in spring. Curb appeal work is best done before photos, not after.

Summer: the growth season

June through September is when Florida humidity does its worst. Algae on north facing walls, black streaks on roofs and green film on concrete cleaning all accelerate. Afternoon storms keep everything damp, which is exactly what organic growth wants.

Summer is a fine time to clean, and it is when most people finally call because the problem has become impossible to ignore. Just know that a summer clean in a heavily shaded yard may not hold quite as long as the same clean done in March.

Fall: the best time for pavers and entertaining spaces

October and November are excellent. The heat breaks, the growth cycle slows, and anything you clean now tends to stay clean through the cooler months. If you host over the holidays, a fall cleaning of the exterior cleaning, pool deck and walkways is well timed.

Winter: the quiet season, and the best availability

December through February is our lightest booking period, which usually means faster scheduling. The work holds up well because growth is slow, so a winter clean often looks good for a long stretch.

If you only clean once a year, late winter or early spring gives you the most visible benefit for the longest stretch. Call (904) 506-7656 to get on the schedule.

Signs it is time regardless of the calendar

  • Black streaks running down your roof from the ridge
  • Green or grey film on the driveway that gets slick when wet
  • Dark patches on the north or shaded side of the house
  • A screen enclosure that has gone dull or spotted
  • Any letter from your HOA

Any one of those means the growth is established and waiting for a better month will only make it harder to remove.

What about pollen season?

Northeast Florida pollen typically runs heavy from late February into April and coats everything in a yellow film. Washing during the peak is a little like mowing in the rain. If pollen is your main complaint, the more effective plan is a rinse during the season and the real cleaning once it settles.

We work throughout St. Johns, St. Augustine, Fleming Island, Orange Park and the surrounding areas year round.

Key takeaways
  • You can clean year round here. There is no frozen season to work around.
  • Late winter to early spring gives the longest lasting visible result.
  • Fall is ideal for pool decks, pavers and entertaining spaces.
  • Winter has the best availability if scheduling speed matters to you.

Frequently asked questions

Can you pressure wash in the rain?

Light rain is not a problem for most exterior cleaning and can even help with rinsing. Heavy storms and lightning stop work for safety reasons. We reschedule at no charge when weather does not cooperate.

Should I wait until after pollen season?

If pollen is the main thing bothering you, yes. If you have algae, black roof streaks or slick concrete, do not wait. Those are growth problems that get worse and harder to remove over time.

How long does a house wash last in Florida?

Most homes look clean for roughly a year. Heavily shaded properties, homes near water and north facing walls can start showing regrowth sooner.

Is it worth cleaning before the holidays?

Yes, and October to November is the right window. The work holds well through the cooler months, so it still looks good in December.
