The Tampa Bay Exterior Cleaning Calendar: What to Do and When

Quick Answer: There is no bad month to clean in Tampa Bay, but there is a sensible order. February through April is pollen. May is the window to get gutters clear before storms. June through November is hurricane season, with the peak in August and September. November through April is the dry season, which is the right window for paver sealing and any large job that needs a dry forecast. Algae grows year-round here — it just grows fastest in the wet season.

Most exterior cleaning advice is written for places with four seasons. Tampa Bay has two: wet and dry. That changes what matters when.

Here is how the year actually runs, based on what we get called about month to month.

February to April — pollen season

Oaks and pines coat everything in a yellow-green film for roughly eight weeks. The nuisance is obvious; the part people miss is that pollen is organic matter, and organic matter sitting on a damp surface is food for the algae that moves in behind it.

Pool cages and lanais take the worst of it because a screen catches and holds pollen rather than shedding it. Cars, walkways, and north-facing walls follow.

The practical move is to wait until the heaviest fall is over rather than cleaning in the middle of it. Cleaning in week two of an eight-week pollen season buys you about a fortnight.

May — the gutter window

May is the last quiet month before storm season, and it is the single best time to get gutters cleared.

Pinellas and Pasco take 50-plus inches of rain a year concentrated from June through September. A clogged gutter does not slow that water down, it redirects it — over the back edge into fascia and soffit, down the wall, and into the ground right at the foundation.

Gutter cleaning is 25% off added to any roof or house wash, which makes May a natural month to bundle. (What it costs.)

June to November — hurricane season

Peak is mid-August through October, not June. Two things matter in this stretch.

Walkway and driveway traction. Storm prep means carrying panels and furniture across your own walkways in the rain. Algae film that is merely ugly on a dry day is genuinely slippery wet.

Roof documentation. A soft wash does not make a roof more windproof and we will not pretend otherwise. What it changes is what the post-storm photos say. A roof black with algae reads as neglected to an adjuster even when it is structurally sound.

Full detail in the hurricane prep guide.

November to April — the dry season, and the best window for big jobs

This is the part most homeowners get backwards. Algae growth slows in the dry season, so people assume there is nothing to do. In practice this is the easiest and most reliable window for the largest jobs.

Paver sealing especially. Sealer needs dry pavers and a dry forecast afterward. In the wet season we are scheduling around afternoon storms; in the dry season the work is straightforward. If you are planning paver cleaning and sealing, this is the window to book it.

Roof and house washing are equally effective year-round — the biocide does not care about the season — but scheduling is easier and you are not competing with storm-season demand.

What does not follow the calendar

Two things run on their own clock regardless of month.

Roof cleaning cycles. Most Tampa Bay roofs want cleaning every two to three years, driven by shade, tree cover, and how fast your particular roof dries. A heavily shaded north slope may need it sooner. That cycle does not reset in January.

Waterfront homes. Salt is a year-round load, and coastal properties generally want a tighter interval than inland ones — closer to 9 to 12 months.

Common questions

What is the best time of year to pressure wash in Florida?
There is no bad month, which is the honest answer. Florida’s dry season, roughly November through April, is the easiest window for big jobs like paver sealing because sealer needs dry surfaces and a dry forecast. Everything else is driven by what is actually happening to your house that month rather than by the calendar.

Does rain ruin a soft wash?
No. The biocide does its work in the first several minutes and rain afterward does not undo it. What rain genuinely affects is sealing work, which needs dry pavers and a dry window afterward, so paver sealing is the one service we schedule around the forecast.

When should I clean gutters in Tampa Bay?
Twice a year suits most homes, with the more important one before peak storm season. A gutter full of oak debris does not slow a tropical downpour, it redirects it over the back edge into fascia and soffit and down against the foundation.

Is it worth cleaning in winter if algae grows slower?
Yes, for two reasons. Algae growth slows in the dry season but does not stop, and the dry season is when scheduling is easiest and paver sealing is most reliable. Winter is the least urgent and most convenient time to get the big jobs done.

The short version

When	What matters most
Feb–Apr	Pollen; clean after the heaviest fall, not during
May	Gutters cleared before storm season
Jun–Nov	Walkway traction, roof documentation; peak is Aug–Sep
Nov–Apr	Dry season — paver sealing and big jobs
Year-round	Roof cycle every 2–3 years; waterfront on a tighter interval

None of this is urgent in the way seasonal marketing usually implies. Exterior cleaning in Florida is maintenance, not emergency work, and the honest answer to “when should I do this” is usually “when it is actually due, which we will tell you at the quote.”
