The first morning back, the driveway isn't the color you left. Green in the shady corners, black film along the lanai, sand washed to the low end. That's seven months of wet season at an empty house, and most of it comes off. Below is what to check this week, and the list for next April.

What Actually Happens to Pavers Over a Florida Summer

Southwest Florida gets most of its rain between June and September, and it arrives as a daily afternoon dump. Warm, wet, shaded surfaces are exactly what algae and mold want. Add pollen, leaf litter, and irrigation running on a timer whether anyone's home or not, and an unattended paver surface can go from clean to green in one season.

While you're up north, this is what's working on your pavers:

  • Organic growth. Algae, mold and mildew take hold on anything that stays damp. Shaded areas and the north side of the house go first.
  • Irrigation overspray. One head hitting the driveway every other morning keeps a strip permanently wet and can leave mineral or rust staining behind.
  • Leaf and debris stains. Wet leaves sitting on pavers for weeks leach tannins down into the surface. Those are real stains, not dirt.
  • Joint sand movement. Heavy runoff pushes sand out of the joints, especially on a slope or anywhere water sheets off a roof.
  • Sealer wear. UV keeps eating the sealer all summer whether the house is occupied or not.

None of that is dramatic on any single day. Seven months of it stacked up is what makes a driveway unrecognizable.

When You Get Back: What to Look At First

Walk the property before you unpack. You're not looking for dirt. You're looking for the things that get worse if you ignore them.

  • Green or black film. Normal after a wet summer. It comes off with the right cleaning.
  • Pavers that rock or sit low. Step on them. Movement means the base under them moved, and no amount of cleaning fixes that.
  • Open or washed-out joints. Look for gaps, or for sand piled up at the low end of the driveway.
  • A rust-colored arc. That's the sprinkler. It's a mineral stain, not general dirt, and it needs a different treatment.
  • Dark rings and outlines. Wherever a planter or a mat sat all summer.
  • Water that soaks in instead of beading. The seal is done.

A Green Driveway Isn't a Ruined Driveway

Plenty of people walk into this November arrival. You pull up to a house you haven't seen since spring, and the driveway is green and the pool deck is black in the corners. It looks like the surface is destroyed.

Usually it isn't. Organic growth lives on top of the paver, and a proper paver cleaning takes it off. The problems that actually cost money are structural, settled pavers, a washed-out base, joints that emptied over months of runoff. Those are separate from the green, and they don't improve on their own. So the honest order is clean it, look at what's underneath, then decide about sealing.

What we don't recommend is renting a machine and going after seven months of growth yourself the week you land. Too much pressure on pavers blasts out joint sand, etches the surface, and can leave wand stripes across the whole driveway. That's a bigger repair than the algae was.

Before You Leave: The List

This is the half nobody does, and it's the half that matters more. Everything you handle in April is something you don't come home to in November.

  • Get the surface clean before you go. Growth spreads from growth. Leaving a patch of algae in the corner of the lanai leaves a starter culture for the wet season.
  • Check your sealer. Spray water on a few spots. If it beads and sits, the coat is still working. If it soaks in and darkens the paver, the coat is spent, and summer is hard on bare pavers.
  • Look at the joints. Low or empty joints let water run down into the base instead of across the top.
  • Aim the irrigation. Point the heads at plants, not at pavers. This is the most common cause of the ugly stripe people find in the fall.
  • Trim what overhangs. Branches and heavy plantings hold moisture on the surface and drop debris all summer.
  • Move what's sitting on the pavers. Planters, mats and furniture feet leave outlines. Anything flat on the surface traps water under it for months.
  • Clear the drains and downspouts. Blocked water finds a new path, and that path usually crosses your pavers.

Seal Before You Go, or After You Get Back?

Both work. They protect different things.

Sealing in spring means the surface goes into the wet season protected. Water, stains and growth have a harder time getting into the paver, so you come back to a driveway that cleans up easy instead of one that needs restoration. The trade is that you're not there to enjoy it, and the coat spends its first months taking the worst weather of the year.

Sealing in fall means the pavers get cleaned and sealed right before the months you're actually here. The surface looks its best while you're using it and while people are visiting. The trade is that the summer damage already happened, so the cleaning ahead of the seal is a bigger job.

If your pavers are sealed and the coat still has life in it, waiting for fall is fine. If the coat is worn out or the pavers have never been done, getting paver sealing handled before you leave is the better trade. Bare pavers plus a Florida summer is the combination that produces expensive problems.

The Problem With Being Gone Half the Year

Maintenance is a schedule, and a schedule is hard to keep from another state. Most seasonal owners end up in the same loop. Everything looks fine in March, nobody touches it all summer, and by December it's a big job again.

That's what a standing maintenance arrangement is for. Instead of remembering to book something from another time zone, the cleaning and the reseal interval run on a set rhythm and somebody has eyes on the surface. If that's the part you keep losing, our maintenance program page has the current details.

Reseal Timing for a Seasonal Home

Inland, a commercial-grade sealer applied in multiple coats generally runs 2 to 3 years before it needs redoing. Closer to the water, plan on less. Salt air is hard on sealer.

Being away doesn't extend that. Sun, rain and salt consume a coat, not foot traffic, and all three keep going with the house empty. If anything, a seasonal home does better slightly ahead of the interval than behind it, because you only get a few weeks a year when scheduling the work is convenient at all. Booking the reseal for the same stretch every other year, either right after you arrive or right before you leave, is the easiest way to stop guessing.

Frequently Asked Questions

Should I shut the irrigation off while I'm gone?

That's a landscaping call, not ours. What we'd ask either way is that you aim the heads off the pavers. Sprinkler overspray running on a timer for seven months is the most common source of the mineral and rust staining people find when they get back.

Is it better to clean the pavers before I leave or when I return?

Before you leave, if you're only doing one. Growth spreads from existing growth, so heading into the wet season with a clean surface means less of it in November. Most seasonal owners end up doing a light clean before they go and a full clean and reseal cycle in the fall.

Will sealing keep my driveway from turning green?

It helps a lot. Sealer closes up the surface so there's less for algae to grip, and it makes whatever does grow much easier to remove. It's not a permanent block. Nothing outdoors in Florida is. Sealed pavers just come back cleaner with less work.

Can you do the work while I'm out of state?

Yes. Exterior work doesn't need you standing there. We need access to the property and a working outside spigot, and we'll walk you through what we found afterward. If you want it done before you land, tell us your arrival date when you call.

I came back to sunken pavers. Did the rain do that?

Water moving base material is the usual cause, yes. Heavy summer runoff washing under a section is common here. Cleaning and sealing won't fix it. The pavers have to come up and the base has to be corrected. Rocking or dipped areas are worth looking at before they spread.
