You land at TPA in late October, pick up the car, drive through the gate, and the house looks... older than you left it. Snowbird home exterior cleaning in Tampa Bay exists because a Florida summer is four uninterrupted months of heat, daily rain and 75% humidity, and an unoccupied house has nobody walking past the north wall noticing the green creeping up it. Nothing went wrong. The climate simply did what it does, without an audience.

Here's what actually happened while you were gone, and the order to undo it.

What a Tampa summer does to an empty house

June through September in Tampa Bay delivers roughly 30 inches of rain, near-daily afternoon storms, and overnight dew points in the low 70s. That's a greenhouse. Every porous exterior surface on your property spent four months warm and wet.

• North and east elevations pick up the most growth, because they dry slowest. That's where the green haze on stucco starts.
• Tile and shingle roofs develop or deepen black streaking from Gloeocapsa magma, a cyanobacteria that feeds on limestone filler in roofing material and thrives in exactly these conditions.
• Pool cage screens go from clear to hazy. Mildew grows on the screen itself and in the frame channels, and from inside the lanai it reads as "the screen looks dirty" long before it reads as mold.
• Pavers and concrete grow algae in the joints and low spots, which is also why they're slicker underfoot in October than they were in April.
• Irrigation runs all summer with nobody adjusting it, so sprinkler overspray leaves mineral and rust tracks on walls, garage doors, statuary and driveway edges.

What order should a seasonal home be cleaned in?

Top down, hardscape last. Skipping the sequence means cleaning things twice.

1. Gutters and roof debris — four months of oak, pine and palm drop, plus whatever the storms delivered.
2. Roof cleaning — low pressure and chemistry, never mechanical force, on tile or shingle.
3. House washing — walls, soffits, fascia, gutter faces, exterior light fixtures and front door.
4. Pool cage and screens — both faces of the screen plus the frame.
5. Windows — after the house wash, so you aren't cleaning glass twice.
6. Driveway, walkways, pool deck and patio — the dirty water from everything above ends up here, so it goes last.
7. Paver sealing, if it's due — typically every two to three years in Florida, and only on a fully dry, fully cleaned surface.

How far ahead of arrival should this be scheduled?

Two to three weeks before you land is the sweet spot. That gives room for Florida's weather to reschedule a day without pushing the whole job past your arrival, and it lets any paver sealing fully cure before cars and furniture come back.

October and early November are the busiest weeks of the year for exterior work in Avila, Cheval and the other gated communities where a large share of homes are seasonal. Everyone comes back at once. Booking in September for a late-October clean is ordinary; calling the week you land usually is not.

The part most people underestimate

This is genuinely harder than it looks from the plane. A seasonal house isn't just dirtier — it's dirtier in ways that need different chemistry on each surface. The same mix that clears algae off a screen enclosure will damage the finish on sealed travertine. The pressure that's right for a concrete apron will etch stucco. Sprinkler rust needs an entirely different treatment from organic growth, and the two often sit six inches apart on the same wall.

Add to that: on an empty property, nobody has been watching the irrigation, so the landscaping around the house is either overgrown against the walls or has been overwatering one corner of the driveway all summer. A crew that does this weekly will flag both while they're on site.

A practical arrival checklist

• Book exterior cleaning 2–3 weeks out
• Ask for the roof to be inspected for debris in valleys and tile pans while the crew is up there
• Have the irrigation heads checked and redirected away from walls and hardscape
• Trim landscaping back off the house so walls can dry
• Get the pool cage done before you host anything
• If pavers haven't been sealed in three years, schedule it for this visit rather than next
