Short answer: Most patios in Volusia County need a clean every 6 to 12 months. A shaded patio under a covered lanai or overhanging trees can need it sooner than that, since shade and moisture together are exactly what let mildew and algae take hold on concrete and pavers in the first place.
What sets the pace
A patio in full sun and open air tends to dry out fully between rains, which slows down both mildew and algae. A patio tucked under a roofline, a covered lanai, or a canopy of trees stays damp far longer, and that dampness is the main reason one patio can need cleaning twice as often as another patio on the same street.
Trees change the schedule more than most people expect
Homes near the beach or under trees tend to need washing more often across the board, and a patio is one of the first places on the property that shows it, since falling leaves and constant shade both feed the same growth that makes a patio look tired well before the calendar says it should.
What to look for between cleanings
A green tint settling into the grout lines, or a faint slickness underfoot near the shaded edges, are both early signs the patio has started growing mildew again, even before it is obvious to the eye looking across the whole surface at once.
Keeping it on autopilot
Puma Pass books the patio every 6 months at 15% off, and you can skip or cancel anytime without a penalty. For a shaded patio that tends to land on the shorter end of that 6 to 12 month range, staying on that schedule usually keeps it from ever getting to the point of looking really bad.
What a delayed clean actually costs you
A patio left well past its window does not just look worse, it also tends to take a little longer to bring back to a clean finish, since deeper buildup needs more passes with the surface cleaner to fully lift.
Staying inside the 6 to 12 month window, or sooner under shade, generally means each visit is a quicker, more routine job rather than a harder one.
In Volusia County
Volusia County property records show 56% of homes here were built before 1990. Decades of shaded corners and Florida humidity on that many older properties is why a 6 to 12 month cleaning window is what keeps a patio looking right year over year.
Questions people ask
Does a covered lanai need cleaning more than an open patio?

Often yes, since the cover keeps the surface shaded and damp longer than open concrete gets between rains, which speeds up mildew growth underneath it.
Can I stretch the schedule if my patio gets full sun?

A sunnier, drier patio can often go toward the longer end of the 6 to 12 month window since it dries out faster between rains than a shaded one does.
Is there a way to avoid remembering to book it?

Puma Pass handles that by booking the patio automatically every 6 months at 15% off, with the option to skip or cancel anytime.
Does furniture or a rug on the patio slow down mildew?

Anything sitting on the surface for long stretches traps extra moisture underneath it, which can actually speed up mildew growth in that spot rather than protect it. Moving furniture around occasionally helps the whole surface dry more evenly.
